1. As an important transportation hub connecting the north and the south, Changsha's industrial structure is also moving towards high-end manufacturing, modern service industry and high-tech industry. However, Wuhan is not perfect in transportation network and scientific and technological innovation resources, and its future development potential is not great.

2. Changsha has been strongly supported by national policies, such as the construction of a series of national demonstration zones, such as national high-tech development zone, national independent innovation demonstration zone and national economic and technological development zone, which has provided strong policy support for the development of Changsha. However, there are relatively few national demonstration zones in Wuhan, and the policy support is not as strong as that in Changsha.
