Be alert! This virus is designed to "start" children, which can seriously cause shock!

  Recently, Niu Niu (a pseudonym), a 1-year-old child, developed symptoms of vomiting and diarrhea. On the third day, his symptoms did not improve, but he also had a seizure. His parents rushed him to the hospital. Combined with clinical manifestations and examination results, the doctor diagnosed that Niu Niu was suffering from "acute gastroenteritis with benign convulsion". The convulsion was caused by impaired digestive function, while vomiting and diarrhea were infected with rotavirus.

  After testing, the child’s stool was positive for rotavirus. According to the doctor, rotavirus is mainly transmitted by fecal mouth, and infants with imperfect gastrointestinal function and low immunity are susceptible groups.

  "Rotavirus is a common epidemic pathogen in children. It often causes gastrointestinal symptoms, such as vomiting and diarrhea. Severe diarrhea can lead to serious electrolyte imbalance and a symptom of dehydration. Rotavirus is also contagious." Jiang Jie, deputy director of pediatrics at Changsha Central Hospital, said.

  The doctor reminded that families with infants should pay attention to prevention when entering the high incidence period of rotavirus.

Be alert! This virus is designed to "start" children, which can seriously cause shock!

  What is rotavirus?

  Rotavirus (RV for short) is the main cause of severe diarrhea in infants and young children. The main route of transmission is fecal-oral route, and it can also be spread through close contact or respiratory tract. Autumn and winter are the peak seasons of epidemic. Rotavirus is divided into eight groups, which are A, B, C, D, E, F, G and H respectively. Among them, group A is the most common one, and 90% of cases are caused by it.

  Infants and young children are vulnerable to rotavirus because of their immature gastrointestinal tract and weak defense ability. Group A rotavirus is one of the most important causes of severe diarrhea in infants and young children all over the world, and it is also one of the main causes of death among children under 5 years old in developing countries. Almost all children under 5 years old have been infected at least once.

  What are the characteristics of rotavirus?

  1. Epidemic season: mainly in autumn and winter, but it can occur in all seasons.

  2.
How to spread: Rotavirus is mainly transmitted through faecal mouth. There are a lot of rotavirus in the excrement or vomit of children infected with rotavirus. If food, drink and use are contaminated with viral excrement or vomit, such as hands, clothes and utensils, rotavirus will be directly or indirectly transmitted to others.

  3.
Susceptible population: Rotavirus is a common cause of viral gastroenteritis in children. Therefore, the incidence population is mainly children, and the high incidence age is between 6 months and 3 years old. Infants and young children at this stage lack anti-bacteria and have poor anti-virus ability, so they need to be vigilant.

  4. Sources of infection: patients (infectious in acute phase and 4-8 days after illness) and asymptomatic virus carriers (infectious without illness).

  What is the performance of rotavirus?

  Sick children will vomit at first, and then have different degrees of diarrhea, mostly accompanied by fever. In severe cases, they will have the clinical characteristics of large stool, more water, more times and less urine.

  Infected children are generally not too serious. Proper rehydration can heal without medicine. However, when diarrhea (vomiting) is serious, it should not be ignored, and medical treatment should be sought in time.

  Children will go into shock and even die because of severe dehydration, especially babies younger than 1 year old. A small number of babies infected with rotavirus will also be complicated with myocarditis, convulsions and pneumonia, etc., which should also be paid attention to and treated promptly.

  Note: If the child’s symptoms do not improve within three days of treatment or any of the following symptoms appear, he should also seek medical attention immediately:

  ① The number and quantity of diarrhea increased;

  ② Frequent vomiting;

  3 obvious thirst;

  4 can’t eat normally;

  ⑤ fever;

  ⑥ Blood in stool.

  How to avoid rotavirus infection?

  Rotavirus enteritis is a self-limiting disease, which usually heals itself in about a week. The general treatment principle is to prevent and correct dehydration, use drugs rationally under the guidance of doctors and actively prevent complications.

  How to prevent this disease? Pay attention to these five points:

  1. At present, there is no specific anti-rotavirus drug. Therefore, vaccination against rotavirus is the most effective measure to prevent rotavirus acute gastroenteritis.

  2. Babies and their caregivers should develop good hygiene habits, especially pay attention to hand hygiene, and do not touch mouth, eyes, nose and food with dirty hands; Don’t let the baby eat his hands, and clean them in time.

  3. Pay attention to family hygiene, the room is often ventilated, and the baby’s utensils (bottles, bowls, spoons, etc.) need to be cleaned before use, and the clothes, quilts, toys, etc. should be changed frequently.

  4. Encourage and insist on breastfeeding.

  5. Items contaminated by rotavirus should be thoroughly disinfected by high temperature, disinfectant or sun exposure.

Some thoughts on using big data to alleviate the practical problems of homogeneity and comparability of price statistics

  ■ Wang Jiangming

  "Homogeneous comparability" is an important principle followed in the statistical investigation of PPI, CPI and HPI in China at present, and it is the basis for comparability between the price in the reporting period and the price in the base period. With the development of economy and society, the needs of the masses are more abundant and diverse, and the principle of "homogeneity and comparability" is also facing more challenges in practice. Under the background of the continuous updating of information technology and the continuous advancement of statistical modernization reform, how to make full use of big data, expand the sources of price statistics data, improve the system and methods of price statistics, keep pace with the times and improve the practical operability of the principle of homogeneity and comparability and the accuracy of price comparison is testing the wisdom of all parties.

  First, the homogeneity of price statistics is facing the "difficulty" of practice.

  At present, China’s more concerned price indexes mainly include industrial producer price index (PPI), consumer price index (CPI) and residential sales price index (HPI). All the above price indexes are "pure price indexes", that is, the price index only reflects the market price changes caused by the changes in market supply and demand and the purchasing power of money, and is a relative quantitative index reflecting the trend and degree of price level changes in different periods. This requires eliminating non-price factors such as quality, appearance, production and supply in the statistical process to achieve "homogeneity and comparability". According to the feedback from the front-line work of price statistical investigation, the practical operability of "homogeneous comparability" will become weaker and weaker if the traditional price statistical investigation method is simply adopted, and it will be difficult to match with the ever-changing social development. If it is not optimized, it will inevitably affect the credibility of statistical investigation.

  (A) the lack of some prices affects "homogeneity and comparability".

  1. The price of the previous period in HPI survey cannot be obtained. At present, the sales price surveys of newly-built houses in 70 large and medium-sized cities in China are all comprehensive surveys, and the basic data directly use the online signing and filing data of local real estate authorities, including the project name, project address, building number, total floor number, floor number, residential structure, total transaction price, construction area, signing time, administrative division, etc. The authenticity and reliability of the basic data are guaranteed. However, the previous period prices of newly-opened projects and intermittent sales projects in the online signing record data are naturally missing, so it is necessary to supplement the previous period prices when calculating the price index, which requires a higher method, and there are certain subjective factors and estimation errors when the big data information is not fully utilized.

  2. Some conditions in PPI survey have changed. According to the existing system, the price survey of industrial producers is carried out monthly, and the "representative enterprises" regularly submit the price of "representative products". The report submitted by the enterprise includes the unit price in the reporting period and the average unit price in the last month. The unit price in the product reporting period is the simple arithmetic average of the unit prices taken twice on the 5th and 20th of the reporting month. In the front-line work of PPI survey, all localities try their best to choose products with great influence on the national economy and people’s livelihood, stable production, development prospects and local characteristics, that is, "representative products", but there are many categories of PPI survey. Taking the ex-factory price survey of industrial producers as an example, industrial products of 41 industrial categories, 207 industrial categories and 666 industrial categories were investigated and divided into 1310 basic categories. In practice, it is difficult to ensure that the same product of the same enterprise has a completely homogeneous sales record in the reporting month and last month. Even if the same product of the same enterprise is oriented to different customers, the price is different. For example, when the customer’s credit is good, the cooperation time is long or the order quantity is large, the price is often lower. The above situation can be regarded as the lack of the price of a "representative product" at a certain price acquisition point, and the price needs to be filled after removing the non-price change factors. Under the current traditional way of not using big data, this work is mainly done manually by enterprise statisticians. However, due to the limitations of professional knowledge, work experience, market judgment and other conditions, enterprise statisticians have different understandings of "homogeneity and comparability", which may affect the accuracy of price surveys.

  (B) the special attributes of products affect "homogeneity and comparability".

  1. The heterogeneity of residential products is outstanding. In HPI survey, it is difficult to follow the principle of homogeneity and comparability in price statistics of both newly-built commercial houses and second-hand houses. As we all know, as a special commodity, it is difficult to achieve absolute consistency in specifications, models and sizes like other commodities. There are differences in geographical location, supporting facilities and residential environment between the two different houses. Comparatively speaking, the heterogeneity of second-hand houses is more prominent, even if they are located in the same residential area, there are great differences in building location, specific floors, unit orientation, building depreciation, interior decoration and other qualities.

  2. Some categories are frequently updated. Clothing products in CPI and electronic products in PPI survey all have the phenomenon of rapid update. At present, the CPI survey is mainly conducted by hand-held data collector, and the survey is conducted directly by means of fixed person, fixed point and timing. Clothing products pay more attention to fashion, and the clothing of the same brand has changeable characteristics in style design, fabric selection, color matching, etc. In addition, clothing products are seasonal and generally have a short life cycle, so it is often difficult to collect sustained and stable prices under the conditions of fixed person, fixed point and timing. PPI survey also stipulates that when selecting representative products, products with relatively stable production should be selected. "Once selected as representative products, it is necessary to continuously investigate for a period of time." When products are included in statistics, they are often in a relatively stable price stage, which easily leads to underestimation of the price index. This is also one of the important reasons why the ex-factory price index of clothing products in CPI and communication equipment, computers and other electronic equipment manufacturing industries in PPI has been "overcast" for many years, which has a certain gap with the actual feelings of the people.

  (3) The impact of big data indirectly affects "homogeneity and comparability".

  In the era of big data, a huge amount of information is generated, and people have more ways, wider channels and richer channels to obtain information, which also poses a great challenge to the traditional government statistical system. At present, there are many institutions or enterprises that publish various price indices in the society, with diverse data sources and different calculation methods. There is also a certain gap between the indices of each period and the data officially published by the National Bureau of Statistics. Most people don’t know or understand the principle of "homogeneity and comparability" in government price statistics. They simply judge by subjective feelings and question the government statistics. In this case, if we can’t do a good job of network public opinion monitoring and interpretation quickly, it will inevitably weaken the authority and credibility of government statistics. Take CPI as an example. A few years ago, some enterprises published the online shopping price index, and some researchers used it to evaluate the CPI released by the National Bureau of Statistics every month, believing that there was a calculation error in the CPI data. In fact, the company’s price index is only calculated by the transaction data of its e-commerce platform, which is far from the full sample requirements. Another example is the house price index. The National Bureau of Statistics officially released the sales price index of commercial housing in 70 large and medium-sized cities. At the same time, we can also see the relevant price indexes released by different institutions on the Internet platform. Except for the National Bureau of Statistics, the house price indexes of other institutions are mostly calculated based on the average prices of transaction samples in various cities, without distinguishing different apartment structures or fully considering "homogeneity and comparability", so there are bound to be differences with official statistics.

  Second, government statistics share the "machine" of big data development

  For government statistical work, big data is data, methods and their technical integration that are processed and mined at high speed with modern information technology and architecture, and have high application Value and decision support function. Generally speaking, it has the characteristics of "multi-V", that is, huge data Volume, Variety of data types, fast processing speed, great application value and authenticity. It is undeniable that big data provides unprecedented conditions and opportunities for the information reform of government statistical source data and macroeconomic measurement. Due to the wide range of sample collection and high statistical frequency, price statistics has become one of the most significant areas directly affected by big data. The exploration of using big data to improve price statistical surveys such as CPI, PPI and HPI is on the way, and the dilemma of "homogeneous comparability" in practice is expected to be continuously alleviated and even effectively solved.

  (1) The application of big data to price statistics is one of the important contents of promoting the reform of statistical modernization.

  In 2020, the Fifth Plenary Session of the 19th CPC Central Committee made a major deployment to promote the reform of statistical modernization. In 2021, the National Bureau of Statistics formulated the Reform Plan of Statistical Modernization in the Tenth Five-Year Plan period in order to build a modern statistical investigation system suited to the modernization of the national governance system and governance capacity, pointing out that "a new round of scientific and technological revolution has developed in depth, which has provided a strong impetus for improving statistical productivity, changing statistical production methods and reshaping statistical production relations", and at the same time, it has also seen that the digital transformation of statistical work is lagging behind, and put forward "improving and perfecting price statistics" and "promoting the application of departmental statistical data" In the same year, the "Work Plan for Big Data Application of National Bureau of Statistics (2021)" was issued, which clearly stated that it was necessary to "play the role of big data in expanding data sources, improving the efficiency of statistical investigation, improving the quality of statistical data, and achieving new breakthroughs in the statistical application of big data." It can be seen that the government level has fully understood the historical opportunities and important challenges brought by big data to government statistics.

  (2) The application of big data to price statistics has been cutting-edge research.

  Foreign scholars have studied the application of big data in the field of price statistics earlier. In 1993, Diewr proposed that scanning data could be used in the compilation of price index, thus reducing the substitution deviation and new product deviation in the compilation of price index. In recent years, some domestic experts, scholars and statisticians have also put forward pertinent opinions from various angles. He Qiang (2015) said that the future application of big data in China government statistics should be based on the wide application of big data, especially cloud computing, and establish a data quality evaluation mechanism of big data to create a more scientific and informative "second track" of government statistics data sources. Xie Zuozheng and Wang Kelin (2016) suggested using e-commerce data, scanning data and other data sources to realize the overall grasp of industrial product structure and ex-factory price. Dong Qian (2017) combined the characteristics of the characteristic price method and the repeated transaction method, compiled the second-hand housing price index through the repeated characteristic "R-H" transaction method, and selected different matching spaces to achieve maximum homogeneity and comparability under the existing data conditions. Yu Fangdong (2018) believes that the compilation of CPI based on online data is different from the traditional sampling statistical theory and method in terms of product matching, comparability and index compilation method, and new theories and methods need to be created.

  (3) The application of big data to price statistics has been explored in practice.

  Abroad, Australian Bureau of Statistics, American Bureau of Labor Statistics, Statistics New Zealand, etc. have formally used scanning data to compile their own CPI. In recent years, China’s statistical departments have taken the lead in the development and utilization of big data in government agencies, and steadily promoted the research and application of big data in government statistics in accordance with the core application ideas of "overall design, leading research, easy before difficult, and professional breakthrough". As early as 2014, the National Bureau of Statistics signed a big data strategic cooperation framework agreement with six companies including Tencent, and carried out substantive cooperation in the fields of public opinion monitoring and house price statistics. In recent years, the system and methods of price statistics have been constantly improved and updated. In terms of CPI survey, in December 2020, in order to meet the requirements of big data and informatization for price survey, the Urban Department of the National Bureau of Statistics formulated and issued the Measures for the Application and Management of Scanning Data, which set clear requirements for the national CPI survey professional norms to apply scanning data to price collection, and encouraged all provinces and cities to actively carry out pilot work in cities and counties with mature conditions. Taking Fujian Province as an example, the Fujian Investigation Corps of the National Bureau of Statistics has carried out pilot work in 17 investigation outlets in 8 cities and counties in the province, and the form of "coexistence of old and new" has been taken as an important supplement to the traditional pricing method.

  Third, using big data to improve the "road" of price statistics homogeneity and comparability

  As mentioned above, there have been many researches and practical explorations on the application of big data in price statistics at home and abroad, but there are not many achievements in the specific research on the homogeneity and comparability of price statistics. The author tries to combine some research achievements at home and abroad and the first-line practical experience of price statistics, and puts forward some path ideas for solving the practical problems of homogeneity and comparability of price statistics by using big data for reference.

  (1) Follow the principle.

  1. The principle of bold exploration and long-term gradual progress. "Homogeneous comparability" has always been a key and difficult issue in the practice of price statistics. It is obviously impossible to find the optimal solution by relying solely on traditional survey methods, and big data has opened up a new data source for price statistics with its advantages of high frequency, fine granularity and diversification. Under the wave of the new era, only by boldly exploring and promoting in-depth cooperation between statistical departments and social institutions and big data enterprises in accordance with the path of "complementary advantages, mutual benefit and win-win, data orientation and gradual progress" can big data become an important supplementary source of price statistics. At the same time, however, at this stage, China’s use of big data to alleviate the dilemma of "homogeneity and comparability" of price statistics in practice has difficulties in data acquisition and quality assurance, as well as bottlenecks in technology and methods, which can not completely replace the traditional survey methods for the time being, and can only be used as a useful supplement to the existing methods. Using big data to optimize the homogeneity and comparability of price statistics should be a long-term and gradual process, which requires repeated experiments and research. It is necessary to prevent "big data arrogance" and avoid damaging the science and rigor of government price statistics due to rashness.

  2. The principle of security, confidentiality and continuous stability. The Statistics Law of the People’s Republic of China clearly stipulates that the objects of statistical investigation must "provide true, accurate, complete and timely information needed for statistical investigation", and also requires "statistical institutions and statisticians to keep confidential the state secrets, business secrets and personal information they know in their statistical work." The use of big data is beneficial to alleviate the problem of "homogeneity and comparability" in price statistics. However, big data has a wide range of sources, and it often needs the help of private enterprises and institutions outside government departments to implement applications. Enterprises pay attention to commercial interests, which is different from the purpose of government departments to serve the public. Therefore, in the process of data cooperation, how to prevent potential leakage risks and security risks becomes the key, and a complete legal system needs to be established to regulate them. In addition, the characteristics of CPI, PPI, HPI and other price statistics require the samples to be as stable as possible for a certain period of time. If Internet companies and data asset companies engaged in data cooperation fail to survive for a long time, it will inevitably affect the continuity of price statistics. Therefore, it is an indispensable and important principle to ensure the continuous stability of data acquisition channels.

  (2) Expand data collection methods.

  1. Make full use of electronic scanning data. Electronic scanning data is to scan the EAN code of goods in sales outlets through scanning equipment to obtain product feature information such as product name, product number and product model. When trading, the electronic processing system of retailers can also record relevant retail outlets and types, prices, trading quantity, trading time and other information.

  The advantages of this acquisition method are as follows: first, the discrete price data of "fixed person, fixed point and timing" are replaced by high-frequency continuous scanning data to eliminate the deviation of discrete data; The second is to replace manual data with information data to avoid the measurement error of manual price collection and the burden of answering questions at price collection outlets; Third, product update information is more accurate, and it is more timely to include statistics. More comprehensive scanning data can provide more support for CPI survey to achieve "homogeneous comparability" accurately.

  The shortcomings of this collection method are as follows: first, the application field is relatively limited, mainly used in CPI survey, and can not be used more in PPI, HPI and other price surveys; Second, the requirements for outlets are high, and the survey outlets need to have a complete database system. Large shopping malls, supermarkets, hospitals, etc. can facilitate the collection of scanning data, but the grounded farmers’ markets and small shops are difficult to obtain due to equipment restrictions; Third, it is difficult to maintain data. Compared with other countries that have adopted electronic scanning data in the world, China has a vast territory, strong regional color, obvious differences in regional development and price level, and many chain enterprises in the consumer market. Statistics departments need more enterprises to effectively cooperate in scanning data collection, which greatly increases the difficulty of data collection and data security.

  At present, this method has been piloted in some conditional areas in China, but only in the form of "coexistence of old and new" is used as a reference for compiling price index. When the conditions are ripe in the later stage, we can consider gradually weighting the electronic scanning data and the traditional "three-fixed-straight" price acquisition data to calculate CPI.

  2. Appropriate use of the network to capture data. Network crawling data refers to a collection of data that is partially targeted, professional and accurate by using Internet search engine technology and classified according to certain rules and screening criteria, also known as network crawling data.

  The advantages of this collection method are as follows: first, the data source is rich, which can greatly increase the sample size of the basket of goods and services. Combined with the specific index compilation method, it can effectively solve the problem that the price of the reported month or last month is missing and cannot be "homogeneous and comparable" in price statistics such as HPI and PPI; Second, the acquisition frequency is high, and the compilation frequency of price index can be increased from monthly to semi-monthly, weekly or even daily, so as to improve the timeliness of price data release and better serve the public and decision-making; The third is to reduce the labor cost of the survey, use Internet technology to capture the price data, cross the geographical and time constraints, and greatly reduce the price collection burden of statisticians, survey enterprises and auxiliary investigators in grass-roots units.

  The shortcomings of this collection method are as follows: first, it has great technical influence. For example, due to website changes and interception technical factors, the data captured by the network may be interrupted, repeated and incomplete, so it is necessary to continuously improve the capture technology to improve its stability; Second, the samples are not stable enough, and the products captured by the network are updated faster than those in the traditional collection mode. If the current index calculation method is still used, it is difficult to match effectively; Third, it is difficult to identify the transaction price. No matter whether it is online shopping platform or house price trading platform, most of the online data are sellers’ quotations or listing prices, and there is still a gap with the actual transaction price. If it cannot be effectively identified, it may affect the true accuracy of the data.

  At present, Norway, Britain, the Netherlands and other countries have partially used the network to capture data in the process of CPI compilation and made breakthrough progress. In China, the application of online capture data in price statistics is still in the exploratory stage, and it is suggested that it can be piloted in some areas with mature information technology, such as Jiangsu, Zhejiang and other developed areas of online shopping, giving online capture data a certain weight to compile CPI;; You can also try to compile HPI by using the housing brokerage platform to capture data and POI data derived from geographic information system, combined with repeated transaction method and characteristic price method in developed areas such as Shanghai and Shenzhen.

  (3) Improve the index compilation method.

  1. Try to compare the prices of fixed groups. In the new era, with the expansion of data collection methods, we should appropriately break through the constraints of traditional statistical theories and methods in the face of the larger and faster total data in price statistics. Drawing lessons from Belgium, Britain and other countries, this paper compares the prices of relatively homogeneous and comparable products of fixed groups according to the data captured by the network and electronic scanning data, and observes and reflects the price changes of consumers buying homogeneous and similar products. During the comparison period, the product groups are fixed, but the specific products are variable. Under this method, we will calculate the price ratio of the same product group in different periods under the basic classification, rather than the price ratio of specific products. The premise of adopting this method is to cluster a huge number of products with price, to maximize the high homogeneity and similarity of products within the group, to ensure that there is no significant difference between products within the group and to reduce the deviation of price index. At the same time, because of breaking through the traditional framework and changing from "one-to-one" comparison to "group-to-group" comparison, it is necessary to study and explore the index method more suitable for new data sources.

  2. Promote the practical application of the characteristic price method. Eigenvalue method, also known as Hedonic model method, is a method to homogenize samples by using Eigenvalue model. At present, France, Germany, the Netherlands and other European countries generally use the characteristic price method to calculate the house price index. This method is also applicable to the calculation of price indexes with many categories such as CPI and PPI. The characteristic price method holds that the price is determined by the utility brought to people, and each utility corresponds to a certain characteristic price value. After regression analysis with a large number of actual transaction data, the influence of characteristic change is eliminated item by item from the total price change, that is, the pure price change caused by the relationship between supply and demand and the purchasing power of money is obtained, that is, the "homogeneous and comparable" price change. Hedonic functions are mainly in linear form, semi-logarithmic form, exponential form and double logarithmic form, which can be selected according to specific needs. At present, there are many mature theoretical studies on this method at home and abroad, but the premise of using this method is to have a lot of product price and characteristic information, and the calculation tends to be complicated, which requires high background data processing ability and operator quality, and the specific practice in China is still shallow. Electronic scanning data and network crawling data make it possible to obtain large-scale commodity information, which will inevitably provide more favorable conditions for the implementation of the characteristic price method, making it an important method to optimize the homogeneity and comparability of price statistics at present. It is suggested to try it out in some areas and gradually promote it.

Power improvement, new towing qualification, brand-new Ford Explorer price of 309,800 yuan.

On September 13th, the brand-new Ford was officially launched, with a price of RMB 309.8-399.8 million. Some models of the new car were upgraded in towing qualification, the engine performance was slightly improved, and the car was also equipped with 8155 chips.

The envy of the old car owners of the new car should be that the Kunlun Peak Edition model has added 2.1 tons of towing qualification, and at the same time, the blind area monitoring area of the new car has also been upgraded, expanding the monitoring range, making it easier to observe the trailer in real time, and the driving mode has also added a special towing mode, which greatly improves the driving safety under towing conditions.

The layout of the car is the same as that of the old model, and six-seat and seven-seat layouts are provided. The new model of Kunlun Peak Edition is made of suede in many places, which looks more luxurious and exquisite. In addition, the new car is also equipped with 8155 chips, 5G car network and Baidu map, which makes the car smoother and smarter. At the same time, it is equipped with the BlueCruise driver assistance system, which supports the functions of changing lanes with the turn signal lever and intelligent comity in the lane, making driving easier.

In addition, the new Ford Explorer canceled the knee airbag, mobile phone key PAAK, APA one-button parking assistance, voice control second row seats and other configurations.

summary

On the whole, the new explorers are mainly optimized for some pain points of the old models, which is more in line with the positioning of light off-road SUVs. At the same time, the new towing qualification also brings more playability. However, compared with the models of the same class, it has more advantages, not only has stronger power, but also has plug-in models to choose from.

I hope that the new car can also launch a hybrid version in the future, and then reduce the terminal discount more, so as to win the favor of more consumers.

I wonder if you are excited about this car introduced today? If you think so, today’s car is still worth recommending.

New trends such as quality, youthfulness, and township leadership are obvious in the big data of Spring Festival consumption upgrading.

  Topic:During the Golden Week of the Spring Festival this year, the sales of retail and catering enterprises nationwide exceeded one trillion yuan for the first time. E-commerce big data shows that the Spring Festival consumer market is in the process from quantitative change to qualitative change, and consumers’ choices are more diversified and qualitative. The growth rate of consumption in 4-6 tier cities is leading, and the core consumers are younger.

  The Spring Festival is the most important traditional festival in China, and shopping is naturally the highlight during the Spring Festival. According to the data released by the Ministry of Commerce, during the Golden Week of the Spring Festival in 2019 (February 4 to 10), the national retail and catering enterprises achieved sales of about 1,005 billion yuan, an increase of 8.5% over last year’s Golden Week of the Spring Festival. At the same time of the steady and rapid growth of consumption during the Spring Festival, new highlights are also highlighted: commodity consumption pays more attention to quality; Food and beverage consumption is more year-round; Experience consumption such as traveling and watching movies is more popular. Emerging consumption highlights such as online consumption, customized consumption, experience consumption and smart consumption are numerous.

  With the development of e-commerce platform and the increasing variety of goods, consumers are more and more accustomed to online shopping for new year’s goods and gifts during the Spring Festival. According to big data from JD.COM, the amount of orders placed during the Spring Festival holiday (from New Year’s Eve to the sixth day) increased by over 60% compared with the same period of last year, leading the retail market. The consumption during the Spring Festival reflects the consumption trend of China’s consumer market, such as the diversification and quality of consumers’ choices, the leading growth rate of consumption in cities in line 4-6, and the younger core consumers.

  The wave of quality consumption leads the consumption upgrade

  The report of the 19th National Congress of the Communist Party of China pointed out that Socialism with Chinese characteristics has entered a new era, and the main contradiction in our society has been transformed into the contradiction between the people’s growing need for a better life and the unbalanced development. In recent years, consumers’ pursuit of high-quality and beautiful life has been continuously improved. The e-commerce platform represented by JD.COM provides a wealth of goods and convenient services that don’t close, ensuring that consumers can enjoy convenient and fast shopping experience during the holiday season, and making Spring Festival consumption more fresh and quality.

  During the Spring Festival, the top five categories of JD.COM platform sales are: mobile phone communication, computer office, household appliances, clothing, shoes and boots, and home furniture and home improvement. The top five sales categories are: local life/travel, maternal and child toys, food and beverage, beauty care, clothing and shoes.

  JD.COM platform sales data shows the new bright spot of Spring Festival consumption: quality consumption is very obvious. According to big data from JD.COM, during the Spring Festival, the categories with the highest customer unit price were watches, mobile phones, jewelry, computer office and clothing shoes and boots. Compared with the same period of last year, the categories with the most obvious increase in customer unit price were kitchen utensils, local life/travel, gift bags, home furniture and home improvement, and clothing shoes and boots. It is worth noting that among these categories, consumers prefer to buy higher-end brands among similar products, and the consumption upgrading trend is the most obvious.

  Compared with the past, the accompanying gifts for visiting relatives and friends during the Spring Festival this year are also more diversified. JD.COM big data shows that teaching AIDS, health care products for the elderly and gold ornaments have become popular gifts for Chinese New Year. Compared with the same period of last year, the sales volume of teaching AIDS increased by 710% year-on-year, the order amount of gold jewelry increased by 126% year-on-year, and the order amount of health care products such as aged milk powder, calcium tablets and vitamins increased by 128% year-on-year. The e-commerce retail platform, which is constantly enriched in commodity categories, provides consumers with a broader range of choices and becomes a good choice to meet consumers’ diversified and personalized shopping needs. It is not difficult to see from the consumption structure that the consumption proportion of non-physical goods, such as travel, entertainment and health, continues to increase compared with previous years, which also represents that China consumers pay more and more attention to cultural products and quality services.

  The e-commerce platform also facilitates consumption during the holiday season. New Year’s Eve and dinner are indispensable in the Spring Festival. Even if the choice of offline supermarkets and vegetable markets is limited, consumers can buy the required ingredients or even semi-finished meals at any time on the e-commerce platform. The convenient retail platform allows consumers to eat well and buy easily during the Spring Festival. Compared with the same period of last year, the categories with the fastest year-on-year growth in fresh sales during the Spring Festival are: poultry, eggs, frozen food, seafood and aquatic products. In the consumption of fresh food, frozen food is the sales champion, among which Yuanxiao, hot pot pills and dumplings are all popular goods.

  The changing trend of consumer demand is a clear consumption upgrade, which means that in addition to providing high-quality goods, enterprises need to continuously provide very personalized services. Ren Xingzhou, a researcher at the Institute of Market Economy of the State Council Development Research Center, believes that diversification of commodities and taking consumers as the center is an important starting point for promoting the steady growth of consumption through high-quality services.

  Strong consumption vitality in generate, a low-tier city.

  The continuous improvement of consumption quality during the Spring Festival is a spark of passion after the traditional taste of the year meets the digital economy. Advanced consumption during the Spring Festival is not only reflected in the diversification and individualization of categories, but also in the sinking of consumption upgrading, and the strong consumption vitality of low-tier cities and more consumers in generate.

  Ten departments, including the National Development and Reform Commission, recently jointly issued the "Implementation Plan for Further Optimizing Supply, Promoting Steady Growth of Consumption and Promoting the Formation of a Strong Domestic Market (2019)", and put forward 24 specific measures in six aspects, which pointed out that it is necessary to stimulate urban and rural consumption and meet multi-level and personalized consumer demand.

  The high-quality retail platform represented by JD.COM Platform brings a variety of goods to consumers through "no closing time during the Spring Festival", and the intimate service of door-to-door delivery makes shopping convenient and easy. Take New Year’s Eve and all kinds of dinners as an example. Consumers used to visit vegetable markets and supermarkets, but now they can buy the required ingredients directly on the e-commerce platform at any time. A convenient retail platform like JD.COM allows consumers to "eat all over the world" during the Spring Festival and make fresh and delicious food within reach.

  According to big data from JD.COM, during the Spring Festival, consumption from low-tier cities showed strong growth, among which consumption growth in fourth-and sixth-tier cities was the highest. Behind the ease and convenience of shopping, there is an increasingly perfect logistics infrastructure layout. Now, with the gradual sinking of consumption channels, the gap between urban and rural areas has gradually narrowed, and the "small town youth" in low-tier cities have also released strong consumption vitality. On the one hand, young people who worked hard in the city returned home for the New Year, which effectively promoted the consumption upgrade in their hometown; On the other hand, the sinking of e-commerce channels has enabled more and more rural users to enjoy the convenient services of e-commerce anytime and anywhere during the holidays.

  Returning population promotes the popularization of advanced consumption patterns.

  Every year, the Spring Festival is the peak for travelers from all over the country to return home. The data shows that the number of floating population in China is 247 million, which is equivalent to one in every six people. These floating population will bring the consumption habits they developed in big cities back to their hometown, which is also driving the popularization of advanced consumption patterns and habits.

  The floating population in different cities also have different consumption habits for purchasing new year’s goods. According to JD.COM Big Data, the floating population in the Yangtze River Delta region is the most willing to spend money on buying new year’s goods. On average, they have to buy more than 1,000 yuan for their hometown.

  In recent years, the new year’s goods purchased by returning youth have also effectively verified the growth of consumers in China. For example, large-scale electrical appliances and large-scale furniture were the main products in 2016 and 2017, but their rankings dropped sharply in 2018. In 2018, watches and beauty and skin care products that are smaller in size and relatively inexpensive have become a new generation of new year’s goods. It is worth mentioning that local travel and car maintenance ranked second and third respectively in 2018, which means that young people in the new era are more inclined to buy services for their parents than to buy more practical furniture and appliances.

  The analysis of JD.COM Big Data shows that when a commodity is bought back to its hometown as a new year’s goods, it will have a direct expansion effect. In the following six months, the sales volume of typical "returning home for new year’s goods" will increase significantly, which means that a new consumption habit has flowed from the purchase of floating population to the hometown and has become a new consumption trend in new regions. This means that the floating population is changing the overall consumption structure through their consumption behavior.

  From hoarding radish, cabbage, rice flour, grain and oil, clothes, shoes and socks in the past, to jumping out of the shackles of "food and clothing" and enjoying all kinds of special goods anytime and anywhere, this is behind the unremitting pursuit and continuous creation of the broad masses of people for a better life. With the people’s pockets getting bigger and bigger, their consumption tastes are getting higher and higher, and their desire for consumption is getting stronger and stronger. The rapid improvement of national consumption capacity is particularly obvious during the Spring Festival, and the high-quality e-commerce platform brings high-quality goods and considerate services to consumers with rich goods and convenient services, which is a clear manifestation of the improvement of China’s economic level and the continuous upgrading of consumption.

Late at night Musk, big announcement!

Tonight, Musk has become the focus of global attention.

At around 21: 25 on March 14th, Beijing time, Musk’s SpaceX heavy-duty launch vehicle was ignited and launched. At present, the results of the third test flight have far exceeded the previous two.

SpaceX announced that the propellant transfer demonstration (T+24 minutes) and the payload door closing process (T+28 minutes) of the starship spacecraft were successfully completed. Musk, the founder of SpaceX, announced on the social platform that the "Starship" has reached the surrounding speed! Congratulations to the SpaceX team! !

This is the third test flight of Starship, and the first two tests exploded. On the first test flight last April, the rocket exploded a few minutes after liftoff; On the second test flight in November, Starship separated the first booster from the upper spacecraft. In Musk’s vision, the "starship" is a vehicle to send humans to Mars, which is also the core goal of his creation of SpaceX.

Thanks to the rapid development momentum, SpaceX’s valuation is rising wildly. According to a report by Bloomberg in December last year, SpaceX’s latest valuation reached US$ 180 billion (about RMB 1,294 billion), second only to ByteDance among unicorn enterprises in the world.

Starship launched into space.

On the evening of March 14th, Beijing time, SpaceX, founded by Musk, launched the third test flight of the Starship heavy launch vehicle.

According to the latest news, the rocket with the largest volume and the strongest thrust in the history of the earth, with the vision of establishing a permanent base on the moon and landing on Mars, has been ignited and launched at around 21: 25 Beijing time.

After launching T+3 minutes, the first and second stages of the Starship heavy launch vehicle were successfully separated.

Eight minutes after the launch of T+,the six raptor engines of Starship successfully turned off, and the spacecraft entered the taxiing phase. It is expected that the engines will be restarted at T+40 minutes. At present, the results of the third test flight have far exceeded the previous two.

SpaceX announced that the propellant transfer demonstration (T+24 minutes) and the payload door closing process (T+28 minutes) of Starship spacecraft were successfully completed. According to the process, the next step is to restart the engine (T+40 minutes) and re-enter the atmosphere (T+49 minutes).

SpaceX said that the T+40-minute engine re-ignition process may have been skipped. In any case, the starship will now embark on the road to the Indian Ocean.

T+1 hour and 3 minutes later, SpaceX said that it has lost the signal with the starship spacecraft and confirmed that it has lost contact with the spacecraft. Today’s test flight can no longer carry out the last step of landing in the Indian Ocean.

After the rocket was launched, later on the 14th, SpaceX founder Musk announced on the social platform that the "Starship" had reached the circling speed! Congratulations to the SpaceX team! !

According to SpaceX official website, on the basis of the second test flight, the third test flight will try more targets, including opening/closing the payload door of the starship aircraft and re-igniting the Raptor engine in space for the first time.

According to the overall process, after taking off, the starship assembly needs to separate the "overweight" propeller from the starship spacecraft, and then the propeller will try to land (on the water), and the spacecraft will continue to carry out a series of tests, and finally fall into the Indian Ocean under controlled conditions.

According to the official timetable, assuming all goes well, the whole process will take about 64 minutes.

On the afternoon of March 13th, local time, the Federal Aviation Administration (FAA) gave the final "green light" for the test flight. The agency said in a statement that it has confirmed that the mission meets all safety, environmental and policy requirements.

In the live online audio broadcast at the end of February this year, elon musk, the founder of SpaceX, once said that the third test flight of Starship can reach the Earth orbit with a probability of 70%-80%. Today’s rockets are much better than during the first and second test flights.

Musk’s "ambition"

This is the third test flight of Starship, and the first two tests exploded.

On April 20th, 2023, the integrated system of the "Starship" rocket and spacecraft made its first test flight. Some of the 33 main engines of the "overweight" booster failed to turn off, which caused the "Starship" to roll in the air only three minutes after launch and triggered the self-destruction program. In addition, the rocket’s super thrust also caused heavy damage to the launch site.

On November 18th of the same year, SpaceX launched the Starship rocket for the second time. After the rocket was launched for less than 3 minutes, the first and second stages were successfully separated. However, the mission control center lost contact with the Starship spacecraft and was forced to start the self-destruction system. CNN reported that the second test flight of Starship went further than when it was tried in April 2023.

According to SpaceX’s explanation, every step of these launches is to achieve future moon landing and longer-term goals.

According to official website of SpaceX, the new generation of heavy-duty launch vehicle "Starship" is by far the largest and most powerful launch vehicle in the world, with a total height of about 120m and a diameter of about 9m. The rocket consists of two parts, the bottom is a "super heavy" booster, about 69 meters high, equipped with multiple "Raptor" engines; At the top is a spaceship, which is about 50 meters high and can be reused.

In Musk’s vision, the "starship" is a vehicle to send humans to Mars, which is also the core goal of his creation of SpaceX.

Up to now, NASA has invested nearly $4 billion in this project. NASA chose "Starship" to carry out the Artemis project in the future and carry astronauts to the moon. According to the current arrangement, Artemis’ manned moon landing plan may be implemented in September 2026.

1.3 trillion super unicorn

In recent years, outside the earth’s atmosphere, Musk’s SpaceX company has developed very rapidly.

According to statistics, in 2023, the world launched a total of 223 launch vehicles and 98 SpaceX launches, accounting for 45% of the global total, slightly less than the sum of other countries; A total of 2,945 satellites were launched in the world, and 2,514 satellites were launched by SpaceX, accounting for 87% of the global total and 6.7 times that of other countries.

In 2023, the United States launched 116 rockets, of which SpaceX accounted for 98 times. The former quasi-national team-ULA (United Launch Alliance, founded by Boeing and Lockheed Martin) only launched three times.

According to Musk’s plan, in 2024, when only falcons (including heavy falcons) are available, SpaceX will launch 144 times, accounting for 90% of the global total, 10 times that of other countries.

Once the starship matures, SpaceX’s orbital quality will account for 99% of the world’s total, which is 100 times that of other countries.

In terms of revenue, estimates show that SpaceX’s revenue has doubled continuously in the past three years, from $2.3 billion in 2021 to $8.7 billion. In 2023, it even achieved quarterly profit for the first time, which became an important milestone of this business model.

According to the forecast, in 2024, SpaceX’s annual revenue will reach about 13.3 billion US dollars (about 95.6 billion yuan). Among them, the rocket launch revenue will increase by more than 55% year-on-year, and the revenue will reach 5.47 billion US dollars, while the growth rate of the star chain will exceed 63%, and the revenue is expected to exceed 6.9 billion US dollars.

Thanks to the rapid development momentum, SpaceX’s valuation has climbed again in the cold winter of technology. According to a report by Bloomberg last December, SpaceX’s latest valuation reached US$ 180 billion (about RMB 1,294 billion), second only to ByteDance among unicorns in the world.

At present, SpaceX is building a closed-loop ecology composed of new space scenes such as rocket manufacturing and launch, satellite Internet, space travel and deep space exploration.

Faced with this huge commercial blue ocean, institutions such as Blue Origin founded by Amazon founder Jeff Bezos, ULA jointly supported by Boeing and Lockheed Martin, Arianespace, a joint venture of the European Space Agency, and the Russian Space Agency are all competing with SpaceX.
