China has been heavily investing in transportation infrastructure since the 1990s. Consequently, connectivity has been significantly improved, both within China and between China and other countries. Such large‐scale investments have been made possible by various financing mechanisms from the central government, local governments, and the private sector. Research findings generally indicate that these infrastructure investments bring economic prosperity to the country, affect the distribution of economic activities, reduce poverty to a certain extent, and promote economic integration. The future trends of connectivity changes in China and relevant policy recommendations are also discussed in this paper.
