③ After the epidemic, the surge in the three major industries must be long-term high-growth industries

Epidemic Afterwards, the three major industries surged. I believe that the entire Chinese people have experienced this epidemic deeply. According to Academician Zhong Nanshan, we must be prepared for a protracted war. If we sort out people's needs during the epidemic, it will not be difficult to summarize which industries will be popular after the epidemic, because where there is demand, there will be supply. In the future, entrepreneurs and ordinary people will seize business opportunities or engage in jobs in these profitable industries, which must be industries with long-term high growth.

The first place is the medical and health industry. Masks, protective clothing, ventilators, testing and treatment equipment and supplies, consumables and medicines, alcohol, disinfectants, and even small cotton swabs, etc., all consume huge amounts and are in huge demand.

Drug research and development, including the development of specific drugs and vaccines. An epidemic that is rare in human history has changed people's understanding and concepts. They are helpless in the face of viruses and bacteria, and how urgent it is to look forward to specific drugs and vaccines.

Currently, the construction of ICU wards is far from insufficient not only in China, but also all over the world. The cost is high, but the market demand is huge. This has caused medicalAcademic circles and policymakers attach great importance to it, and its development potential is huge!

Environmental disinfection industry. The development of new, efficient, non-toxic and practical environmental disinfectants or facilities and equipment is a major trend. Once an epidemic occurs, disinfection and sterilization of hospitals and homes is very important, especially among urban residents who are more aware and are willing to spend a lot of money to purchase and use it.

The second place is peripheral industrial products for epidemic prevention. After experiencing this painful lesson, countries around the world will inevitably strengthen the production, storage and construction of their peripheral products. It cost RMB 300 million to build a hospital in Huoshenshan and Leishenshan in Wuhan, and countless makeshift hospitals have also been built. Think about it carefully, what kind of things will be needed? Everything you must have at home is there, and things you don’t have at home are also there. In the future, all provinces, cities and counties will vigorously build it to prepare for emergencies.

The third place is the leap forward development of the Internet. Internet medical consultation, pharmaceutical e-commerce, online shopping, games, live broadcasts, Internet celebrities and other industries will make adaptive development and major development in response to huge demand.

It must be mentioned that the online education platform has performed very poorly in facing hundreds of millions of students across China during this epidemic. It can be said that it is riddled with holes and overwhelmed, and there are still many hardware, software and network needs. Something that is well developed.

Fourthly, the tutoring industry will definitely have a huge market. During the epidemic, all social training institutions were closed, and many teachers from low- and medium-risk areas came to teach, meeting the needs of especially junior high school students.

Of course, there are many more popular industries, such as delivery, takeout, housekeeping, etc., so I won’t list them all.

First of all, after the epidemic, people have realized the importance of health, and health-related industries will definitely rise, such as fitness gyms and health and nutrition matching industries. Medicine and health include physical health and mental health.

Secondly, electronic industries, such as e-commerce and unmanned retail, will develop more rapidly.

Third, in online education, more and more on-site teaching will be replaced by online teaching. Online office class.

In 2020, the epidemic struck suddenly, and while foreign countries were still denigrating various domestic measures and ridiculing our government’s measures, we were getting better step by step, and they are now Already about to collapse. We have no intention of paying attention to international changes. At present, our focus is on resuming production and grasping the rhythm of making money.

Let me first talk about the financial consumer industry in which I am engaged. It can be said that this epidemic has not only brought the domestic economy to a halt for two months, but has also profoundly affected many real economies, including construction, schools, restaurants, hotels, etc., which our financial brokers have been exposed to the most recently. For one type of people, they may be in the cold winter, but we have seized some of the country's subsidy policies, used the government's interest rate discounts, and hastened to lend money abroad. It can be said that more people need money, and banks are also lending a lot. As an intermediary service in the financial industry, it can be said that we can make a good living for a year.

It can be said that it is almost May now and offline physical training institutions are still not open. Now various online training institutions and software development companies have suddenly become popular, and the number of users has skyrocketed. Through this period of forced use, we cultivated a customer base that grew exponentially. In the later period, through proper utilization of various policies, it will definitely be popular for several years.

The catering industry may need to be reshuffled. My home is in a second-tier city, and there are not many large catering brand companies that are competitive. These group companies will not die easily, but they will not die easily. It’s hard to say, for example, Haidilao. But more of those who died were individual operators. Once the capital chain is cut off, everything is over. On the other hand, this is the time to buy the bottom, and those investors who have funds in their hands may become popular. Some time ago, I saw a person on the Internet who accepted more than a dozen Internet cafes, all at bargain prices. I really envy him for his good luck.

Thank you for the invitation, just a humble opinion, thank you.

A sudden major health and public safety epidemic has changed the development of the global economy. The industries that are obviously beneficial include medicine and biology, video conferencing and online office systems. , Internet of Things, 5G will be vigorously developed, etc.

1. Medical and Health Industry

In this epidemic, the most direct demand is in the medical and health field. In addition to professional medical supplies for front-line medical staff, the most important one is at the public level. health needs will explode.

The epidemic is also a popular health education for the people across the country. In particular, during the epidemic, people found that people with good health and good resistance can often be cured; while those with other concurrent diseases are more likely to be at risk.

From the perspective of supply and demand, on the one hand, as the aging of society further intensifies, the per capita disposable income has steadily increased, and the demand for health has been fully released; on the other hand, medical technology, biotechnology, and intelligence The development of other technologies has promoted a substantial increase in supply-side products and services in the health industry, enabling more health needs to be met.

Affected by factors such as population growth, rising residents' income, and aging, domestic medical and health demand is growing day by day. The medical and health market has undergone earth-shaking changes, and investment and industrial integration are also accelerating.

Therefore, the medical and health industries such as biomedicine, medical services, and medical devices will have considerable development.

2. Video conferencing and online office systems

Similar to telemedicine, video conferencing and online office are not new. In the past, video conferencing was mainly used in very large enterprises such as multinational corporations. Small and medium-sized enterprises rarely use it. The epidemic has caused a large number of companies to postpone their operations or move them online. For small and medium-sized enterprises that cannot start operations normally, they can only migrate part of their work through video conferencing and online office work. With the promotion of this epidemic, video conferencing and online office meetings are ushering in a comparisonbig development.

3. Internet of Things

During this epidemic, all major hospitals are facing the same problem, with masks, protective goggles and other protective supplies in short supply. In addition to the inability to keep up with production capacity due to the Chinese New Year, the reason for the urgent shortage of items is also due to the inaction of a certain association, which resulted in emergency supplies donated across the country lying in warehouses and unable to be delivered to the doctors in need. If the Internet of Things is developed enough, the whereabouts of items can be tracked in real time through the Internet of Things system, making the flow of the logistics system more transparent.

4. 5G will develop vigorously

Whether it is telemedicine, online office, or the Internet of Things mentioned above, these systems have higher requirements for communication systems. The development is also related to the failure of the 4G network to meet the requirements. This epidemic is like a catalyst and will bring opportunities for further development of 5G.

⑤ Direct to Digital Expo丨Blockchain Standardization and Application Innovation Summit released three innovative results

Zhang Ping, chief engineer of the Cyberspace Administration of Hebei Provincial Committee, introduced that blockchain is the One of the hot spots focused on at the expo, the "Hebei Province Blockchain Special Action Plan (2020-2022)" released by Hebei Province last year clarified Hebei Province's blockchain technology and industrial application development goals - by the end of 2022, Hebei Province There are 20 leading companies and leading companies in blockchain-related fields, cultivating a number of blockchain application products, striving to create 1-3 nationally renowned blockchain brands, and forming 3 blockchain industry clusters with regional influence. Park, the competitiveness of the blockchain industry ranks among the top in the country. To this end, Hebei Province is committed to introducing well-known domestic and foreign enterprises, gathering the most advanced technology, the most cutting-edge innovative concepts, and the most high-end human resources to cultivate innovative forces for the development of Hebei's blockchain industry.

"Hebei Provincial Characteristic Agricultural Products Blockchain Traceability Platform" was jointly developed by the Institute of Applied Mathematics, Hebei Academy of Sciences and Huaye Hebei Co., Ltd. Wang Zhiqiang, deputy director of the Institute of Applied Mathematics of the Hebei Academy of Sciences, introduced that the platform fully integrates blockchain with big data, Internet of Things, artificial intelligence and other technologies to realize the full chain traceability of production, logistics and sales information of specialty agricultural products, making production Operators, the general public and regulatory authorities can participate together to build brands, enhance product value and promoteHigh-quality development of agricultural economy.

It is reported that the “Hebei Province Specialty Agricultural Products Blockchain Traceability Platform” has three most prominent features:

First, one vote, one code, and object code locking. Intelligent identification and matching of business entity information and sales documents effectively solves problems such as multiple data sources, poor quality, and inconsistency between upstream and downstream.

Then there is the whole-chain evidence storage and accurate traceability. With the traceability code as the carrier and responsibility and flow management as the core requirements, agricultural product circulation data, electronic vouchers and other information are uploaded to the chain to achieve functions such as data non-tamperability and transaction traceability, and improve data throughput through the standardization of data storage and exchange. Key performance indicators such as volume and system response speed.

The third one is multi-source fusion and targeted regulation. On the basis of the blockchain system, for the characteristic agricultural product industry chain, a fusion model of production, circulation and inspection big data has been established to achieve targeted supervision and intelligent decision-making based on big data analysis, and comprehensively enhance the brand of on-chain products. Credibility.

"After three months of trial, the platform has been connected to 212 agricultural product trading markets, 9,807 online merchants, and 3,484 on-chain varieties, demonstrating strong application demand and development potential." Wang Zhiqiang introduced that the Hebei Academy of Sciences is also exploring another high-quality route, cooperating with the Julu County Government to promote the "One Flower Supports Hundreds of Industries" project, using "blockchain empowering agriculture" as the entry point to create an agricultural digital estate, and then drive the development of agricultural digital estates. The integrated development of primary, secondary and tertiary industries in the county will eventually achieve the goal of "one flower blooming and all industries prospering".

This Blockchain Standardization and Application Innovation Summit is hosted by the China International Digital Economy Expo Organizing Committee and hosted by the China Electronics Technology Standardization Institute, the Software Institute of the Chinese Academy of Sciences, and the Hebei Academy of Sciences.
