The urban agglomeration development plan, as a guiding and binding document for the development of urban agglomerations in my country, is an important policy tool for the country to coordinate regional economic development. The important feature of urban agglomeration that distinguishes it from other economic regions is that there are close and organic connections between the individuals within each city. By judging the development potential and rationality of urban agglomerations, the State Council has successively approved the development plans of 10 urban agglomerations. However, whether the approval and implementation of the urban agglomeration development plan has promoted the economic connection between cities within the urban agglomeration and improved the level of urban agglomeration integration still needs to be empirically tested. Taking the Chengdu-Chongqing region as an example, this paper studies whether and what kind of impact the implementation of the policy has on the economic relations between urban individuals in the region. This paper firstly sorts out the development background, related literature and theoretical basis of the Chengdu-Chongqing region, and then analyzes the mechanism of policy implementation on regional economic linkages from three aspects: factor allocation, market integration, regional division of labor and cooperation. After that, it summarizes the status quo of cooperation and economic development in the Chengdu-Chongqing region after the approval of the "Planning", compares the development status of the Chengdu-Chongqing urban agglomeration and other national-level urban agglomerations, and compares the economic development, economic development and economic development of the Chengdu-Chongqing region before and after the policy. Intuitive changes in bond strength. In the empirical part, this paper uses the "Chengdu-Chongqing Urban Agglomeration Development Plan" approved by the State Council as a quasi-natural experiment, establishes panel data of 21 urban individuals in Sichuan and 30 urban individuals in Chongqing from 2012 to 2019, and uses the double difference model to analyze that the implementation of "Chengdu-Chongqing Urban Agglomeration Development Plan" how to effect of the economic relations between different cities in the Chengdu-Chongqing area.The study found that: (1) The approval of the Plan has a strong role in promoting the overall economic connection of the Chengdu-Chongqing urban agglomeration,and makes it more closely connect. (2) The approval of the Plan has different impacts on Sichuan and Chongqing. The areas included in the "Planning" in Chongqing are positively affected by the policy than those in Sichuan Province that are included in the "Planning". Finally, this paper put forward relevant countermeasures and suggestions on how to promote the integrated development of urban agglomerations and further strengthen the economic connection between regions.
