The global spread of the epidemic has led to the emergence of two new problems: the decline in global demand and the blockage in global supply, and the short-term solutions include stepping up the production of healthy pharmaceutical products and opening up the domestic market. The most important thing for making best use of and cultivating China's domestic market is to promote the formation of a strong domestic market through institutional innovation. Therefore, it is necessary to strengthen competition and promote the construction of regional market integration; to enhance the formation of a strong domestic market through innovation and reform of income distribution systems; and to foster the equal competition of various ownership enterprises to improve the investment desire and investment ability of private enterprises. In the long run, it is impossible for other countries in the world to decouple from China's economy. Therefore, China must further optimize the business environment, especially through further reform and opening-up to reduce business costs and increase its attractiveness to foreign investment. The new round of infrastructure construction is aimed at the weak points of China's future development. In order to improve its economic efficiency, it is necessary not only to make the new infrastructure work in line with the traditional infrastructure, but also to make it match the new consumption. China should do as follows: firstly, use digitalization to transform traditional industries; secondly, accelerate machine substitution to promote industrial upgrading; thirdly, encourage the cultivation and introduction of various digital service providers to form an internationally competitive industrial chain and ecological environment in related fields.
