　　China Economic Net, Beijing, September 21-On the 17th, the central bank launched a one-year MLF (medium-term lending facility) operation of 265 billion yuan in the open market. As no liquidity instruments of the central bank expired, all the MLF funds were put into the market. After the central bank announced the MLF operation, a wave of media made an eye-catching interpretation: "Yang Ma released 265 billion yuan".

　　Is this really the case?

　　The article "Trader Chun Shenjun" pointed out that the central bank is called the bank of the bank. When the bank is short of money, it will borrow from the central bank for emergency. Open market operation is the means by which the central bank lends money to banks. Open market operations are divided into positive repurchase and reverse repurchase. Positive repurchase means that the central bank borrows money from banks to recover liquidity, while reverse repurchase means that the central bank lends money to banks to release liquidity. Every day, the reverse repurchase will expire, and the amount of operation MINUS the amount of maturity is the net investment. There is an index to measure the liquidity of funds: sentiment index of funds. When the index is greater than 50, it means that the funds are tight and the central bank needs to put in liquidity.

　　According to the article, recently, due to the influence of centralized tax payment, the amount of funds in sentiment index has reached more than 60%, so the central bank put in funds to ease the market. "So, this is not what we understand ‘ Release water ’ Regardless of his hundreds of billions, it doesn’t matter how big the number is, because the money will be automatically recovered in a few days. "

　　The article bluntly said that a WeChat official account can pay no attention to it if it only talks about "releasing water" with open market data.

　　For the open market operation of the central bank, the "Lu political commissar’s worldview" made an image metaphor in the article: to a certain extent, the central bank is like managing a pool that pumps water while filling water, and the name of the pool is the interbank market. When the water level in the interbank market is too high, the administrator central bank needs to turn on the pump to pump water; When the water level is too low, the central bank needs to turn on the tap to inject water.

　　From September 1 to 11 this year, the central bank did not invest in the open market, but from December 12 to 18, the central bank began to increase investment, and the cumulative net investment scale reached 695 billion yuan. Why is there such a big change in the scale of delivery?

　　The article explains that when the liquidity is relatively stable at the beginning of the month, the necessity of central bank investment will decline; When paying taxes in the middle of the month to return liquidity, the central bank needs to increase the amount of "water replenishment" in the open market. When the issuance of local bonds increases, the central bank needs to "replenish water" moderately to hedge the impact of local bond issuance and payment; When the funds raised by local bonds are converted into fiscal expenditure, the central bank will reduce the investment accordingly to prevent the "water level" in the interbank market from being too high.

　　So, how to judge whether the central bank is "releasing water"?

　　According to the article "EBS Collection Research", it is not only the open market operation that determines the water level of this pool in the inter-bank market, but there are several pipes for both water inflow and water outflow. For example, the occupation of funds by local debt issuance, the change of foreign exchange holdings, the collection and payment of fiscal deposits, and so on. Whether the central bank is "releasing water" depends not on how many MLFs it has made, but on a key indicator: DR007.

　　DR007 refers to the repurchase rate between banks and banks before. "Interest rate is the price of capital, just like the price of cabbage in the vegetable market. If there is a bumper harvest of cabbage, the price will definitely be low, which is the relationship between supply and demand. The price of funds is the same. If the People’s Bank of China releases water, then DR007 will definitely drop sharply. "

　　According to statistics, in fact, after the latest MLF operation of the central bank, DR007 did not decline. On September 14th, DR007 was 2.62%, and it was still 2.62% on the 17th. On the 18th, DR007 rose instead of falling, reaching 2.71%.

　　The picture comes from the public number of EBS fixed income research.

　　The article "Lu political commissar’s world outlook" also pointed out that while filling water and pumping water in the pool, how do you know whether the water level in the pool is appropriate? The interest rate of inter-bank funds is a very intuitive water level scale. In mid-September, although the central bank increased its efforts in the open market, DR007 remained relatively stable, with no obvious downward trend. Overall, since September, DR007 has fluctuated slightly around the center of 2.62%, reflecting that although the central bank’s investment has changed greatly, the "water level" of interbank liquidity is basically stable.

The State Council joint prevention and control mechanism held a press conference on May 31st to introduce the situation of epidemic prevention and control and vaccination. Since May, a total of 50 new confirmed cases have been reported in China, and new confirmed cases or asymptomatic infected people have been reported for 18 consecutive days, involving many provinces.The epidemic situation is characterized by rapid spread and strong spread of strains. The the State Council Joint Prevention and Control Mechanism has sent a working group to Guangdong to guide the handling of the epidemic..What other latest news is worth paying attention to? Let’s look at it together-

How is the national vaccination going?

As of May 30, the country has reported vaccination with Covid-19 vaccine.639.172 million doses. Vaccination has been accelerated on a large scale, with an average of 12.47 million doses per day since May, 2.58 times that of April, with the highest dose per day exceeding 20 million.We should continue to accelerate vaccination and build the Great Wall of Immunization..

How to arrange the recent vaccination work?

From June 10 to 30, the second dose of vaccination was mainly carried out for these target groups who had already received the first dose.However, for those with special needs, such as going abroad and other epidemic prevention and control, continue to inoculate the first dose of vaccine.After July, the first and second doses of vaccination will continue to be fully promoted., do a good job of COVID-19 vaccine inoculation in an orderly manner.

Is COVID-19 vaccine going to be charged?

At present, our vaccination work is based on the needs of epidemic prevention and control in COVID-19, combined with the actual vaccine supply and the vaccination work arrangement at this stage. We advance by steps, highlight key points, and give informed consent.The principle of voluntary and free vaccinationTo vaccinate all kinds of people step by step.Everyone must not believe in rumors, let alone spread them..

Local sporadic cases have appeared in some places one after another. Will the normalization prevention and control measures be adjusted?

Recently, the local epidemics, especially in Guangzhou and Shenzhen, were all caused by the import of foreign viruses.Shenzhen was caused by the mutant virus first discovered in Britain, and the epidemic in Guangzhou was caused by the mutant virus first discovered in India. The spread ability of these two viruses was enhanced than before..

According to this new situation, all the tools in the toolkit for preventing and controlling the spread of epidemic should be called out, and it should be adopted and implemented accurately and forcefully.It may be strengthened and adjusted accordingly in terms of implementation strength, scope and duration..

Any suggestions for the Dragon Boat Festival holiday?

The advice given by holiday activities related to the past has not changed much. It is still that individuals should take precautions. Personal preventive measures include wearing masks in public places, paying attention to personal hand hygiene and respiratory etiquette.

In addition,People in medium-risk and high-risk areas should try to avoid unnecessary travel and reduce the cross-regional spread of the epidemic..

If you have fever or respiratory symptoms during the trip, you should quit the trip in time, avoid contact with other people and seek medical advice in time.Especially to the standardized medical institutions with fever clinics..

Is the domestic COVID-19 vaccine effective for the mutant strain?

We carried out a cross neutralization experiment in China by using the serum obtained from overseas Phase III clinic, including strains found in South Africa and Britain, including epidemic strains found in different regions of China. Up to now, these sera can still react well with these viruses.It should be said that the vaccine still has good protection..

The variation of the virus is eternal, it happens naturally, and at present,As long as the mutation of the virus can be controlled, the vaccine should still be able to protect the current situation for a long time..

Under some special circumstances, enterprises in China are also ready to develop new vaccines in response to sudden major mutations.Vaccines against mutant strains can be developed quickly..

What are the contraindications of Covid-19 vaccine?

Technical Guide to Vaccination in COVID-19 (First Edition)Five situations of vaccination taboo are specified, including:

1. When Covid-19 vaccine or similar vaccine was inoculated before.Have had allergies, this isAn absolute taboo.

2. Previous vaccinationHaving had a severe allergic reaction.

Step 3 suffer fromUncontrolled serious nervous system diseasesYes.

4. beingFeverOr suffer fromAcute diseaseorPatients with acute attack of chronic diseases.

5. Uncontrolled patients with severe chronic diseasesThese are relative taboos.

(The third, fourth and fifth categories are relative taboos. In the course of clinical research, it is not found that vaccination of these groups of people can lead to serious adverse reactions, but it is listed as a taboo for vaccination in order to prevent and guard against it. )

Some taboos, such as fever, acute disease and acute phase of chronic disease, are temporary. When these circumstances leading to taboos no longer exist,You can be vaccinated after recovery and stable disease control..

·Breast-feeding and menstrual women are not taboo for vaccination. Patients with depression, anemia, heart stent, etcIf the drug is well controlled, the condition is stable or you can live a normal life, you can also be vaccinated.

Whether you are taking antiviral drugs and can be vaccinated with Covid-19 vaccine depends on the condition at that time.If you can’t judge yourself, you can consult a clinician to judge whether you can be vaccinated..

What’s the difference between one shot, two shots and three shots?

What we are currently usingInactivated vaccine, adenovirus vector vaccine and recombinant protein vaccine.. These three types have their own characteristics in vaccine composition, production technology, immune principle and immune procedure.

·inactivated vaccineIn the preparation process, the virus is inactivated after a large number of cultures, purified after verification, and then turned into a vaccine. The main feature of this vaccine is that the technology is very mature, it has been used for hundreds of years, and the quality is very stable.Side effects are relatively few., 2 to 8 degrees storage, easy to transport and use.This vaccine is usually given with two injections.The first needle stimulates the immune system to produce memory cells, and the second needle induces a stronger antiviral immune memory response.

·Adenovirus vector vaccineThe S protein of the virus is introduced into adenovirus type 5 vector, and this antigen is introduced into cells by virtue of the ability of adenovirus to enter cells efficiently, and its expression stimulates the immune system. Because of its high efficiency and relative lack of resources,One shot is the whole process of immunity., you can improve the vaccination rate of the whole process of immunization.

·Recombinant protein vaccineIt is to use genetic engineering technology to set up engineering cells to express virus S protein, so that it can be expressed efficiently, and then it will become a vaccine after extraction.In most cases, this vaccine is given three injections, and the best immune response will be obtained after three injections..

These three kinds of vaccines are safe, effective and quality-controllable.The public can safely choose any vaccine for vaccination.

The public must complete the whole process of vaccination and cannot give up halfway.Otherwise, the best protection effect set by the vaccine will not be achieved, that is, preventing virus infection, preventing illness and preventing severe illness.

We can’t relax other public health prevention and control measures when we don’t reach the group immunity barrier among the people.. We haven’t reached the group immunization standard set by the state. After reaching the standard, the country will have corresponding new prevention and control guidelines.

In June this year, central enterprises achieved operating income of 2.9 trillion yuan and net profit of 166.48 billion yuan, up by 0.6% and 5% respectively.

In the face of the complicated environment, it is not easy for central enterprises to achieve positive growth in revenue and profit simultaneously. On the one hand, the excellent epidemic prevention and anti-epidemic achievements in China have created favorable conditions for the recovery of the national economy; On the other hand, the central enterprises have comprehensively deepened the work of improving quality and increasing efficiency, and made great efforts to expand the market, grasp production, control costs and stabilize investment.

At the press conference of the State Council Office held on July 16th, Peng Huagang, Secretary-General and spokesman of the State Council State-owned Assets Supervision and Administration Commission, introduced the specific situation of the economic operation of central enterprises in the first half of the year, and said that the economic operation of central enterprises had improved significantly, and the positive changes had increased significantly. In June, the income and profits of the same month achieved positive growth simultaneously.

In the first half of the year, the decline in revenue and profit was narrower than that in the first quarter, and both revenue and profit achieved positive growth in June.

In the first half of this year, most central enterprises were affected by the COVID-19 epidemic and encountered difficulties in stages. With the further consolidation of the epidemic prevention and control in China and the accelerated recovery of social production and living order, the production and operation of central enterprises have accelerated since May.

Peng Huagang introduced that in the first half of the year, the central enterprises realized a total operating income of 13.4 trillion yuan, down 7.8% year-on-year, and the decline was narrowed by 4 percentage points compared with the first quarter. The income decline has narrowed for three consecutive months; The accumulated net profit was 438.55 billion yuan, down 37.7% year-on-year, and the decline was 21.1 percentage points lower than that in the first quarter and 12.6 percentage points lower than that in January-May.

In June, central enterprises achieved positive growth in both operating income and net profit. Among them, the operating income was 2.9 trillion yuan, a year-on-year increase of 0.6%, and most enterprises have recovered or exceeded the same period level; The net profit was 166.48 billion yuan, an increase of 64.63 billion yuan compared with May and a year-on-year increase of 5%. It was also the first time this year that the monthly net profit increased positively.

Depending on the industry, the production and operation of key industries have been accelerated and gradually improved.

In the first half of the year, the steel output, crude oil output, power generation and electricity sales of central enterprises have recovered to more than 98% of the same period last year; The orders for new ships increased by 21.2% year-on-year, the installed power capacity increased by 5.1% year-on-year, the sales volume of commercial coal increased by 1.8% year-on-year, and the alumina output and new orders for power generation equipment maintained positive growth.

In the second quarter, the sales volume of refined oil products increased by nearly 40% compared with the first quarter, and it also increased compared with last year. In February, the electricity sales of the two power grid companies plummeted by 10.9% year-on-year, and gradually recovered and improved. In April, the decline narrowed to -1.3%, in May, it turned into a positive growth of 4.6%, and in June, it increased by 6.5% year-on-year.

"The marginal improvement in the physical quantity indicators of basic industries such as oil, electricity and coal reflects the continuous improvement of the national economy and also boosts confidence in the economic operation in the second half of the year." Peng Huagang said that there are also military industries, communications industries and construction industries that contribute a lot to profits.

Looking at enterprises, the operation tends to be stable, and the monthly income and profits of most enterprises have recovered or exceeded the same period.

There were 57 central enterprises whose income increased year-on-year in June, and 33 enterprises whose income increased by more than 10% in that month. The net profit of 58 central enterprises in June increased year-on-year, and that of 46 enterprises increased by more than 10%.

Peng Huagang believes that in the face of this year’s complicated environment, it is not easy for central enterprises to reach a new high in June. On the one hand, the excellent epidemic prevention and anti-epidemic achievements in China have created favorable conditions for the recovery of the national economy; On the other hand, the central enterprises have comprehensively deepened the work of improving quality and increasing efficiency, and made great efforts to expand the market, grasp production, control costs and stabilize investment.

In the first half of the year, the investment in fixed assets was 1 trillion yuan, reducing the operating cost of the whole society by more than 120 billion yuan.

In addition to the positive growth of income and profits, the investment of central enterprises has also taken the lead in achieving positive growth.

In the first half of the year, the central enterprises invested 1 trillion yuan in fixed assets, up 7.2% year-on-year, and the growth rate was 5.9 percentage points faster than that in January-May and 11.7 percentage points faster than that in the first quarter.

Since the full resumption of work in March, the monthly growth rate of fixed assets investment of central enterprises has been 4.1%, 11.8%, 13% and 21.2% respectively, showing an accelerating trend month by month. In the second quarter, the accumulated fixed assets investment was 673.07 billion yuan, up 14.8% year-on-year. By industry, the growth rate of fixed assets investment in power generation, automobile, communication, metallurgy and other industries exceeded 15% in the first half of the year.

In order to help revive Hubei after the epidemic, on June 3, relevant central enterprises and Hubei Province signed a total of 72 cooperation projects with a total investment of 327.7 billion yuan.

With steady investment, central enterprises will continue to exert their efforts. Peng Huagang introduced that in the second half of the year, we will continue to guide and support enterprises to focus on improving industrial basic capabilities, breaking through the weak links of key core technologies in the industrial chain, maintaining industrial chain security and other areas to increase investment, and seize investment opportunities in new infrastructure such as 5G, industrial internet and data centers, actively and orderly promote project construction, do a good job in reserves of high-quality investment projects, actively absorb social capital, and broaden financing channels.

Focusing on the "six guarantees" and the implementation of the "six guarantees" task, the central enterprises have also made every effort to help small and medium-sized enterprises fight the epidemic, reduce costs and tide over difficulties, and resolutely implemented the national policies of reducing electricity prices, gas prices, tariffs, tolls and rents. In the first half of the year, the cumulative operating costs of the whole society have been reduced by more than 120 billion yuan.

Peng Huagang analyzed the composition of this 120 billion yuan: "The two power grid enterprises reduced the user cost by 54 billion yuan, the three communication enterprises made profits by 42 billion yuan, and the three petroleum and petrochemical enterprises reduced the energy cost of downstream enterprises by 18 billion yuan. In addition, the accumulated rent reduction for small and micro enterprises also exceeded 4 billion yuan."

In the second half of the year, central enterprises will continue to support the development of small and medium-sized enterprises in three aspects: increasing the supply of basic oil, electricity and coal transportation; Continue to implement the policy of reducing fees and making profits; Strengthen cooperation with various enterprises, especially small and medium-sized enterprises in the industrial chain and supply chain, and use investment to promote the development of the entire industrial chain and supply chain. "Now we are actively carrying out the work of clearing the debts owed by central enterprises, especially those that have no differences with small and medium-sized enterprises, which should be returned as soon as possible." Peng Huagang said.

We will fully implement the "Three-year Action for the Reform of State-owned Enterprises" and strive to achieve the annual goal in five aspects in the second half of the year.

While speeding up the resumption of production and operation, the reform cannot stop. Recently, the 14th meeting of the Central Committee for Comprehensively Deepening Reform deliberated and adopted the "Three-year Action Plan for State-owned Enterprise Reform", and the prospect of state-owned enterprise reform in the next three years gradually became clear.

Peng Huagang introduced that the "Program" has four "highlights": First, it highlights the implementation and action, and puts forward clear task measures for the timetable and road map of state-owned enterprise reform in various key tasks, so that it can be quantified and assessed; The second is to focus on key points, fill shortcomings, strong and weak items, adhere to problem orientation, and propose targeted measures instead of covering everything; The third is to highlight system integration, coordination and high efficiency. Some reform tasks are difficult to be effective by one measure alone, so it is necessary to comprehensively use multiple measures and take a multi-pronged approach; Fourth, it is difficult to fight the annihilation war. The reform in some important areas has defined the objectives and time limit requirements, and concentrated on tackling the difficulties in the three-year operation.

In the first half of the year, the overall operating performance of central enterprises was better than expected. Can we achieve the annual target if we work harder in the second half of the year? Peng Huagang said that although the production and operation in the first half of the year laid a good foundation for completing the objectives and tasks of the whole year, all the work of the reform and development of central enterprises in the second half of the year was faced with difficulties and pressures, and these five aspects should be strengthened to achieve the goals: solidly promote the steady growth of the management and development of central enterprises; Fully implement the three-year action of state-owned enterprise reform; Fully promote the scientific and technological innovation of central enterprises; Actively promote the layout optimization and structural adjustment of state-owned capital; Do a good job in preventing and resolving major risks.

"Strive for the sustained and rapid growth of the benefits of the vast majority of central enterprises, and strive for the positive growth of the overall benefits of central enterprises." Peng Huagang said.

CCTV News:Flexible solar cells have a wide range of applications in mobile communication, vehicle-mounted mobile energy, aerospace and other fields. Recently, the research team of Shanghai Institute of Microsystems, Chinese Academy of Sciences has developed a highly flexible monocrystalline silicon solar cell that can be bent like a piece of paper and is not easy to break. The achievement was published in the international academic journal Nature on May 24th, Beijing time.

In Shanghai Institute of Microsystems, Chinese Academy of Sciences, researchers showed reporters their high-flexibility monocrystalline silicon solar cell. The solar cell in the hands of researchers is like a piece of paper we usually see, which can be bent at a large angle.

Liu Zhengxin, a researcher at Shanghai Institute of Microsystems, Chinese Academy of Sciences:The photovoltaics (solar cells) we use now are all made of monocrystalline silicon. When we apply stress to it, it is easy to break, especially when we want to make it cheaper and thinner.

Researchers told reporters that it was almost impossible to bend a silicon wafer at a large angle without damage in the past. The main reason is that the mechanical characteristics of the silicon wafer limit its flexibility.

Liu Wenzhu, Associate Research Fellow of Shanghai Institute of Microsystems, Chinese Academy of Sciences:Through analysis, our research group found that under the action of bending stress, the silicon wafer always breaks from the sharp tiny groove area around the silicon wafer. Based on such a discovery, our research group developed a method of smoothing the edge of silicon wafer.

The edge smoothing method mentioned by researchers is to treat the sharp V-shaped grooves on the edge surface and side of the silicon wafer into smooth U-shaped grooves, thus changing the microstructure and mechanical properties of the edge of the silicon wafer, while enhancing the flexibility of the silicon wafer, without affecting the light absorption ability of the silicon wafer. At present, the research team has been able to reduce the thickness of silicon wafer to 50-mdash; 60 microns. Compared with traditional solar cells, the photoelectric conversion efficiency of flexible monocrystalline silicon solar cells produced based on this technology remains basically unchanged.

Di Zengfeng, Deputy Director of Shanghai Institute of Microsystems, Chinese Academy of Sciences:Flexible solar cells will greatly expand the application scenarios of solar energy (photovoltaic), and will better serve the national major projects and the national carbon-neutral strategy of peak carbon dioxide emissions.
