How to Treat the Development of Cloud Economy under the Epidemic

How to Treat the Development of Cloud Economy under the Epidemic

Under the epidemic, the new economy represented by the digital economy quickly fills up its seats to provide protection for everyone’s needs in life. “Cloud Office”, “Cloud Fitness”, “Cloud Concert”, “Cloud Recording”, “Cloud Release”…a business format about “cloud” became standard, which even detonated the term “cloud economy”. Although some people do not understand this concept very well, they have actually participated in it.

There is currently no uniform definition of “cloud economy” in academic circles. Some scholars define “cloud economy” as the economy of cloud computing and cloud services. Joe Weinman, the author of “Cloud Economics-Enterprise Cloud Computing Strategy and Layout”, explained that “cloud economics” is not an esoteric economic theory. The mathematical model is a vivid summary of the technological revolution, the core concept of “flexible cloud computing can effectively enhance the business value of enterprises”. The “cloud economy” we are talking about today mainly defines the business trend of enterprises and society under the massive application of cloud computing.

Since the country put forward the “Internet +” action plan in 2015, “Internet +” has been widely integrated into all walks of life, and the continuous innovation and integration of online scenes and offline scenes has promoted retail, finance, culture and entertainment, medical care, government affairs and other fields The rapid development and the “Internet +” that incorporates artificial intelligence technology is a technology cluster application. From pure software intelligence in the past to hard and soft intelligence today, it has changed people’s daily life and the overall industrial structure. Promoting the consumption upgrade of the market has also played a positive role and has become one of the signs leading the innovation and development of enterprises and society. In this special period of epidemic prevention and control, people rely on online work and life. It is generally believed that this is another rapid development trend in the Internet industry after SARS, which may provide more opportunities for entrepreneurship and employment, or even form new ones. The economic outlet of China-“Cloud Economy”.

Whether it is facial recognition and body temperature measurement equipment, or online check-in and attendance systems, all walks of life are launching various “cloud”-related products. When the market is advancing by leaps and bounds, we should maintain a rational mindset and be cautious and objective about the “cloud economy”. The popularity of the “cloud economy” during this period is mainly affected by the isolation of people at home during special periods, but the most fundamental driving factor is the rapid development of my country’s Internet and logistics industries in recent years. After the epidemic is over, it is a question mark whether the “cloud economy” can continue to be prosperous after being separated from the consumption environment of everyone’s home. In a short period of time, its impact on economic development and entrepreneurship and employment is still limited.

However, it should be noted that during this epidemic, consumers at home took the initiative to apply various “cloud economy” products, which I believe has provided a lot of support for the development of the “cloud economy” industry. The epidemic brings short-term pressure, but also brings opportunities for changes in the industry structure. Take “Cloud Classroom” as an example. The “Suspension of Classes without Suspension” this time is a test of online education. Some pain points such as poor self-control of students in online education have been exposed, and it is believed that the promotion of solving these pain points will become ” The next focus of “wisdom education”. In addition, the formulation and improvement of the “cloud economy” development policy will bring benefits to the better promotion of the development of the “cloud economy” in the future.

After this epidemic, we must not only see the reasons behind the “cloud economy”, but also find new “outlets” from the aspects of economic and social development and lifestyle changes. The government, enterprises and other diversified entities should increase integration and innovation mechanisms to truly endow this new economic form with more vitality and impetus.

China village embodies victory over poverty

Xi Jinping (R), general secretary of the Communist Party of China (CPC) Central Committee and chairman of the CPC Central Military Commission, visits the family of Tang Rongbin, an impoverished villager in the Luotuowan Village of Longquanguan Township, Fuping County, North China’s Hebei province. Xi made a tour to impoverished villages in Fuping County from Dec 29 to 30, 2012.[Photo/Xinhua]

Xi’s visit in 2012 pointed way for nation’s efforts in improving people’s livelihoods

The village where Gu Rongjin has lived for his entire life was on the verge of disappearing 10 to 20 years ago, with few means to support local livelihoods, its young people migrating elsewhere, the farmland unattended and the village school closed.

Luotuowan, a village in Fuping county of Hebei province, located at the foot of high mountains and only about three hours’ drive from Beijing, used to typify China’s rural poverty. Its residents lived on a meager per capita income of 950 yuan ($147) in 2012, and over 79 percent of its residents lived below the official poverty line.

On Dec 30, 2012, the village welcomed an important guest. Xi Jinping was on a tour to assess the real situation of China’s poor areas less than two months after he was elected general secretary of the Communist Party of China Central Committee.

Gu, 73, was then the Party secretary of the village and still has a vivid memory of Xi’s tour. “It was about 9 am, and many of us still hadn’t had breakfast. I remembered him lifting the pot lid to see what was being cooked. He wanted to see the real situation,” Gu recalled in a phone interview.

Sitting down with villagers in their rundown homes, Xi made a powerful appeal about the need to fight poverty.

“As long as we have confidence, even loess can be turned into gold,” Xi said during his visit to the county, in remarks that were published last week by Qiushi, the flagship magazine of the CPC Central Committee.

More than eight years on, as China is set to convene a grand meeting on Thursday in Beijing to summarize its poverty alleviation outcomes and honor outstanding units and individuals who have made key contributions to work on this front, analysts said Xi’s remarks in Fuping pointed the way for China’s poverty reduction effort starting from 2012, mapping out targets and priorities and laying the foundation for the targeted alleviation strategy.

China has secured a victory in its fight to eliminate absolute poverty in rural areas after having lifted nearly 100 million people out of extreme deprivation and ensuring that poverty was eliminated in all 832 national-level poverty-stricken counties by 2020.

“Xi’s remarks on his visit to Fuping emphasized a people-centered philosophy, a key development concept that was fully demonstrated during China’s anti-poverty campaign,” said Huang Jikun, director of the China Center for Agricultural Policy at Peking University.

His remarks also set the tone for the country’s efforts to develop a model for poverty alleviation, including steps to attract participation from private capital and focusing on the capacity building of impoverished groups and areas, he said.

The trip, which marked the beginning of China’s intensified poverty reduction efforts, was followed by a host of inspection tours made by Xi and meetings he chaired focusing on poverty alleviation in recent years.

Xi first set out the targeted poverty reduction strategy during his visit in November 2013 to Shibadong, an impoverished village in Hunan province.

At a national work conference on poverty alleviation in November 2015, Xi expounded on the goals, tasks and major measures in the fight against poverty and called for the use of targeted steps in the process.

He listed the fight against poverty as one of China’s three critical battles in a report to the 19th National Congress of the CPC in October 2017, saying that “poverty alleviation should reach those who truly need it and deliver genuine outcomes”.

China has secured a major victory that is worthy of esteem from the whole world and the country has reshaped the look of its poor areas, improved the conditions of production and life and improved the quality of life of the public during the process, Xi said at a key Party meeting in December.

China is the Only Country Whose Major Economy Achieve Positive Growth in Its Economic Development Report in 2020

China is the Only Country Whose Major Economy Achieve Positive Growth in Its Economic Development Report in 2020

According to the Voice of China’s “News Evening Peak” report, the National Bureau of Statistics announced on the 18th that the gross domestic product (GDP) in 2020 will exceed the 100 trillion yuan mark for the first time, with a growth of 2.3% against the trend. Become the only major economy in the world to achieve positive growth. With the new crown pneumonia epidemic raging around the world, the world economy is in a severe recession, and the external environment is more complicated and severe, how exactly is such a beautiful report card written?

2020 is an extraordinary year in the history of New China. In the face of severe and complex domestic and foreign environments, especially the severe impact of the new crown pneumonia epidemic, my country has submitted an excellent report card. The value was 101,5986 billion yuan, an increase of 2.3% over the previous year. The per capita GDP exceeded US$10,000, the economic structure continued to be optimized, and major engineering projects were basically completed. Ning Jizhe, deputy director of the National Development and Reform Commission and director of the National Bureau of Statistics, said: “The epidemic prevention and control work has achieved major strategic results. The main goals and tasks of economic and social development have been completed, and the completion is better than expected. The 13th Five-Year Plan was successfully completed. Officials, the victory of building a well-off society in an all-round way is in sight.”

A decisive victory was achieved in the decisive battle against poverty. Under the current standards, all rural poor people have been lifted out of poverty, 832 poor counties have all been removed, absolute poverty has been eliminated historically, and 55.75 million rural poor people have been lifted out of poverty. In 2020, the seven provinces (regions) of Guangxi, Sichuan, Guizhou, Yunnan, Gansu, Ningxia, and Xinjiang, where there are more poor people, the nominal growth rate of per capita disposable income of rural residents is 0.2-1.7 percentage points higher than the national growth rate of rural residents. The macro-control has achieved remarkable results.

Ning Jizhe said: “The quarterly economic growth indicators have returned to normal levels. In the fourth quarter, GDP grew by 6.5% year-on-year, 0.7 percentage points higher than the same period of the previous year. In 2020, 11.86 million new jobs were created in cities and towns across the country, exceeding the full year. Goals and tasks. In 2020, the consumer price index CPI will increase by 2.5% over the previous year, which is lower than the expected target of about 3.5%. In 2020, the national per capita disposable income will increase by 2.1%, which is basically in line with economic growth.”

The implementation of “six stability” and “six guarantees” has achieved remarkable results, and reform and opening up have created miracles of development. The benefits of multiple ownership enterprises have been improved. Ning Jizhe introduced: “In 2020, the added value of high-tech manufacturing will increase by 7.1% over the previous year, 4.3 percentage points faster than the added value of all regulated industries. The growth of foreign trade and foreign investment is better than expected, and global trade and cross-border investment will shrink sharply. Under the circumstances, my country’s total imports and exports of goods in 2020 hit a record high, an increase of 1.9% over the previous year. From January to November, the actual use of foreign capital increased by 6.3% year-on-year.”

China is the Only Country Whose Major Economy Achieve Positive Growth in Its Economic Development Report in 2020

In 2020, the total economic volume will exceed the one-hundred-billion-yuan mark. Ning Jizhe emphasized that this means that my country’s economic strength, scientific and technological strength, and comprehensive national strength have jumped to a new stage. It is of great landmark significance for building a well-off society in all respects and starting a new journey of building a socialist modern country in an all-round way. He pointed out: “Within 20 years, the total economic scale will be expanded to 10 times, and the achievements have attracted worldwide attention. In 2020, my country’s GDP will reach about 14.7 trillion US dollars, ranking second in the world, and accounting for 17% of the world economy. Around. In 2020, the per capita GDP will exceed 10,000 U.S. dollars for two consecutive years, stabilizing the ranks of upper-middle-income countries, and the development gap with high-income countries will continue to narrow.”

“You can go up to nine days to capture the moon, and you can go down to the five oceans to catch turtles” has become a reality. Technological innovation is becoming more and more active, injecting new vitality into high-quality economic development. my country’s industrial and agricultural production capacity has increased significantly. The total grain output hit a record high and continues to rank first in the world.

“The output of more than 220 kinds of industrial products ranks first in the world, and the added value of manufacturing is expected to rank first in the world for 11 consecutive years. The infrastructure continues to improve, and the total operating mileage of high-speed railways has reached 38,000 kilometers and the mileage of expressways has exceeded 155,000 kilometers. The number of 5G terminal connections has exceeded 200 million, ranking first in the world.” Ning Jizhe said.

More importantly, this has laid a solid foundation for my country to build a new development pattern. Ning Jizhe said that the key to accelerating the formation of a new development pattern in which domestic and international cycles are the mainstay and the mutual promotion of domestic and international cycles lies in tapping the potential of domestic demand, especially consumer demand. He introduced: “my country’s population ranks first in the world, and the middle-income group is also the largest in the world. In 2020, the total retail sales of consumer goods will be close to 40 trillion yuan, the final consumption expenditure will exceed 55 trillion yuan, and the total capital formation will also be close to 45 trillion yuan. This will help my country’s superior market size to be further brought into play.”

In the past year, the total retail sales of consumer goods continued to show negative growth throughout the year, down 3.9% from the previous year. However, the third and fourth quarters have turned positive, especially in the fourth quarter that the total retail sales of consumer goods increased by 4.6%. This rate has begun to approach the normal level of previous years. Ning Jizhe said that my country’s consumption is still the ballast stone for the stable operation of the economy! “From 2011 to 2019, my country’s consumption rate averaged 53.4%. In 2020, despite the impact of the new crown pneumonia epidemic, the final consumption expenditure accounted for the proportion of GDP. It still reaches 54.3%, which is 11.2 percentage points higher than the total capital formation, and is the highest level in recent years. Consumption is still the ballast stone for the stable operation of the economy.”

Ning Jizhe said that due to the epidemic, the growth rate of total social consumer retail sales fluctuated slightly in December, but from the overall trend, my country’s consumption was able to play a fundamental factor in economic development while increasing production and supply. Looking forward to 2021, there are many favorable factors that support the stable recovery of the economy. my country’s economy has a foundation and conditions to continue its steady recovery. Although the current pressure on the prevention and control of the epidemic to “import from external defenses and rebound from internal defenses” is still great, the fundamentals of my country’s long-term economic improvement have not changed.

“The obvious institutional advantage is the fundamental guarantee for economic stability and long-term social stability. Although the epidemic has spread in some places recently, the overall impact on the economy is controllable. We have the conditions and ability to control the spread of the epidemic and operate the economy. Stay within a reasonable range to achieve sustained and healthy development of the Chinese economy.” Ning Jizhe said.

Degree of defect

Basic method for judging the degree of surface defects: under a standard inspection light source, the distance from the observation object is 400mm, and it should be at an angle of 45 degrees with the observation surface. Defects that are not visible at a glance are slight defects, visible at a glance, but not very obvious, are general defects. Visible and obvious defects are serious defects, and defects that are visible at a glance and seriously affect the appearance are fatal defects.

Defect sampling

Appearance is based on 1dm2. The 11.3cm circle selects the most defects.

Inspection methods and inspection standards

The A side should be smooth and flat with no obvious defects. No serious defects are allowed. No hand-painting is allowed to repair defects. Minor defects are allowed. No rough feeling or deformation can be felt by hand. The insignificant general defects have a diameter greater than 1mm is not allowed, less than 1mm is not allowed to exceed 10 points, and the concentration is not more than 3 / cm2. For non-orthographic planes, the standard can be appropriately relaxed. In the detection area, the diameter is less than 1mm. It is not allowed to exceed 15 points, and the concentration is not more than 3 / cm2.

The B surface should be smooth and smooth without obvious defects. No serious defects are allowed. Minor defects are allowed, and there is no rough feeling or severe deformation when touched by hand. Non-obvious general defects are not allowed in the detection area with a diameter greater than 1.2mm and less than 1.2. mm is not allowed to exceed 20 points, and the concentration is not to exceed 3 / cm2. For non-orthographic planes, the standard can be appropriately relaxed. In the detection area, the diameter is less than 1.2mm. It is not allowed to exceed 30 points, and the concentration is not more than 3 / cm2.

The C-plane allows the presence of general defects and serious defects that do not affect the appearance quality. The splicing gap is less than 1mm, which is acceptable. If it is more than 1mm but less than 1.5mm, it can be conceded according to the actual situation, and more than 1.5mm is unacceptable.

KN95 mask, N95 mask, surgical mask, surgical mask FFP2 etc. What is the difference

On market, there are so many kinds of masks, how do we distinguish them and how to choose?

There are two main categories: one is medical masks, one is civilian masks. Medical surgical mask, medical protective mask, N95, FFP2 can be used for protection in medical institutions, KN95 can not be used in medical institutions,? the general public can choose by themselves.What are the differences?

1. Medical: disposable surgical mask (medical nursing mask)

Disposable surgical masks, medical care, general standards: YY0969, usually cannot guarantee the filterability of pathogenic microorganisms, dust. It is? commonly used in conventional nursing care in the hospital, main effect is barrier between medical staff and patients daily cross contamination, no particular high demand. If used by the general public, that is to stop bad breath, the actual effect of protection is not very ideal.

KN95 mask, N95 mask, surgical mask, surgical mask FFP2, etc. What is the difference

2. Medical: medical surgical mask: yy0469-2011

Medical surgical mask must refer to the medical standard yy0469-2011 for production. If the enterprise sets its own enterprise standard to meet or even higher than the requirements of YY0469, it can also be printed on the mask packaging (therefore, it is not necessary to have YY0469 to be qualified, specific or to see the name of the mask and enterprise standard to identify); Surgical masks are mainly used for invasive operations such as surgery and catheterization in hospitals.

YY0469 has bacteria filtration performance requirements to the surgical masks, general filtration efficiency of non oily grains should reach more than 30%, filtering efficiency to achieve more than 95% of bacteria (note, here is not the meaning of N95, don’t be confused with medical respirator), in addition, medical surgical masks have requirement for synthetic blood penetrating (can be as simple as anti permeability) in production. The masks are generally divided into three layers: the internal water absorbing layer, middle filter layer, waterproof layer outside, each layer has a special role.

3. Medical: medical protective mask

Medical protective mask, next is disposable medical nursing mask, also known as medical protective mask, in line with gb19083-2003 standard, the important technical indicators include non-oily particle filtration efficiency and airflow resistance. For diameter (0.24 ± 0.06), the filtration efficiency of sodium oxide aerosol of m is not less than 95%, that is, N95 and above. Inspiratory resistance should not exceed 343.2 pa.

4. Civil use: KN mask: gb2626-2006/2019

KN95 mask, N95 mask, surgical mask, surgical mask FFP2, etc. What is the difference

Kn represents non oil particles, and KP represents oil and non oil particles. Kn is a respirator for the prevention of non oil particles (dust, smoke, microorganism: virus, pathogen) specified in Chinese standard gb2626-2006. In the national standard, the protection level is divided into Kn90, kn95 and kn100, kp90, kp95 and kp100. Kn refers to the prevention of non oil particles, and KP refers to the prevention of oil particles + non oil particles. The latter value represents the protection rate for ultrafine particles. Kn100 respirator and kp100 respirator are more than 99.97% for the protection efficiency of ultrafine particles. Therefore, kp100 mask and kn100 mask with higher protection level in the national standard can provide better protection effect than N95 mask.

See here, don’t know if you have found a problem, just the front, have to tell everyone about medical surgical masks (YY0469-2011) for non-oily filterability of particulate matter for 30% or more, the less than 95% or higher requirement in KN95 mask a lot, so a lot of people naturally think that KN type mask, especially the type KN95 masks, definitely better than the effect of medical surgical masks! Is that absolute?

Surgical masks have impermeable requirements, generally divided into three layers, the outermost layer for the waterproof layer, the most important reason to use masks in the medical environment is to isolate bacteria, and bacteria once attached to the surface of the mask, it is very easy to follow the moist mask directly into the mask, so, impermeable is very important!

And throughout the whole GB2626, there is no standard requirements for KN mask waterproof, not only KN mask, KP mask is not, that is to say, meet all the standards of GB2626 qualified masks, there is no anti-penetration requirements. At this point, KN masks are not as good as surgical masks!

FAQ 1: Is a breathing valve good or bad?

KN95 mask, N95 mask, surgical mask, surgical mask FFP2, etc. What is the difference

Because of wearing a mask of doctors and patients, all can’t promise you must be healthy, don’t (incubation period with infectious) with the virus, and masks airflow with exhalation valve is a one-way only protection, is not good to cut off the route of transmission, from the outbreak control perspective, the two-way protection is the right way, so don’t recommend this type of face mask.

FAQ 2: About the safety mask standard: gb19083-2010 and GB2626 which is good?

Misunderstanding: China’s GB19083 standard does not have “N95”, but the use of “level 1”, “level 2” and “level 3” to express the filter efficiency level, generally level 1 can meet the “N95/KN95” requirements. That is to say, as long as any “medical respirator” that conforms to GB19083 standard, the filtration efficiency of N95 and KN95 has been achieved absolutely.

Difference: GB19083 is the highest standard of medical execution, this is the standard of medical execution, this kind of mask you will find that there is no breathing valve, and are used in the medical scene, of course, if you buy it can also be outside civilian use.

GB2626 is usually used for civilian masks, mainly used as some protection such as painting, welding, industrial and haze and other non-medical scenarios of protection, such as the most common 3M brand KN95 masks is this type!

In addition, like the medical surgical mask of yy0469-2011, GB19083 also puts forward the requirements of “synthetic blood penetration”, and there is also a parameter requirement of “surface wetting resistance”, which makes clear the protective effect of the medical protective mask on blood and fluid, which is not in GB2626 (KN type). See the difference? There is no anti – flying liquid spillage for civil use.
