Under what background is the development of strategic emerging industries cross-border?

In the context of the COVID-19 epidemic. The 2020 High-tech Development Report issued by China Academy of Sciences pointed out that since the 13th Five-Year Plan, especially in the context of the COVID-19 epidemic, new formats and new models have emerged in the fields of digital economy, artificial intelligence, industrial Internet and Internet of Things, and the cross-border integration of strategic emerging industries has developed remarkably. During the epidemic period in COVID-19, a number of new formats and modes emerged, such as "cloud tourism", "cloud exhibition" and "cloud shopping". The empowerment of digital technology not only breaks the physical space limitation of the original industrial development, but also brings a new digital experience of cross-border integration.
