In recent years, there have been frequent major moves for the integrated development of the Yangtze River Delta, indicating that the current integrated development of the Yangtze River Delta has officially entered the fast lane. On the practical and operational level, an important starting point for the integration of the Yangtze River Delta is cross-regional park cooperation and platform construction, which is becoming an important engine leading regional economic development.In the process of regional integration, park cooperation should pay attention to the following aspects:First, we should combine the concept of top-down and bottom-up development. The development of park cooperation in the Yangtze River Delta Park requires not only the top-down overall planning of the government, but also the bottom-up active participation of enterprises.The second is to strictly follow the basic principles of the integrated development of industry and city. In the construction of a cross-regional park, the capacity structure and resource endowment of the city where the park is located should be fully considered, and an irreplaceable characteristic industrial park should be built to achieve the integrated development of industry and city.The third is to consider the push and pull forces of the output area and the target area. In the process of exporting regions to promote the transfer of related industries to other regions through the "enclave economy", it is necessary to achieve the matching and coupling between the transferred industries and the natural resources, labor force and other endowments of the target region.
