Since 2019，global economic growth has continued to resonate downward. The United States and major developed economies in the Eurozone were growing at a low speed，while the economic growth of developing and emerging countries is generally slowing down.

The new strain of coronavirus in 2020 will undoubtedly hit the global economy，and downward pressure will multiply. For urban development and investment corporations，opportunities and challenges coexist.
