How does imported pork regulate the supply and demand of China's pig market during the epidemic?-based on the analysis of African swine fever and COVID-19.

The pig industry is primarily a domestic industry in China is focused on ensuring the domestic pork supply. This paper analyzed changes in Chinese pork imports following the outbreaks of African Swine Fever (ASF) and COVID-19 between January 2017 to November 2020 and evaluated the impact of imported pork on the development of the swine industry in China. The results demonstrated that the shortage of domestic pork supply changed the import volume. ASF transformed imported pork from a complementary product to meet the diversified needs of domestic consumers into a critical substitute required to fill the supply gap. Following the COVID-19 outbreak, the substitution effect of imported pork decreased. ASF, has caused the supply capacity of pork in China to decrease, the price of pork to increase, leading to increased pork import in January 2019. At the end of 2019, pig slaughter decreased, while China cut tariffs on imported pork. The COVID-19 outbreak did not reduce China's pork imports in China, which declined after the global COVID-19 outbreak. Imported pork has made up for the supply gap during COVID-19, not impacting the level of production of the swine industry in China.

Research on Cold Chain Transport of Vaccines in Major Outbreaks

In the face of the sudden outbreak of new type of coronavirus, the virus is spreading at a faster rate than expected, which seriously threatens people’s life and health and national security. According to the World Organization, infectious diseases have been at a high incidence in the last two decades. How to transport kits and vaccines safely and efficiently to suspected cases and patients in a short period of time is related to the speed of national control of the epidemic. This paper first analyzes the scale of the pharmaceutical cold chain market in China, analyzes the policy of the pharmaceutical cold chain industry issued by the state, and analyzes the problems existing in the pharmaceutical cold chain industry;then it analyzes the influence of epidemic situation on cold chain transportation, and finally puts forward the safe and efficient transportation scheme of vaccine under epidemic situation.
