Abstract: Regional coordinated and integrated development is an important focus point for optimizing regional economic layout and building a unified national market. Taking the Yangtze River Economic Belt as an example, a theoretical logical framework for regional coordinated and integrated development is constructed with local government governance as the core, supported by factors, industries, and space. On this basis, the concept of community is introduced, and a long-term mechanism for regional coordinated and integrated development in the Yangtze River Economic Belt is proposed, which is based on the concept of community governance. The core of common governance lies in establishing mechanisms for governance coordination, element coordination, industry coordination, and spatial coordination, handling the four major relationships between government and market, development and protection, inward and outward, and one domain and the whole well. According to the above coordination requirements, the policy path for the coordinated and integrated development of the Yangtze River Economic Belt mainly includes the following points. Firstly, we should take breaking down local administrative divisions as the leading factor, forming a new regional development relationship of government cooperation and market competition. Secondly, we should explore the construction of a regional unified and open factor market with the core of achieving free flow of factors. Thirdly, we should focus on streamlining the industrial development chain, and build a domestic value chain system along the Yangtze River Economic Belt. Fourthly, we should optimize the large-scale regional spatial planning that integrates multiple regulations with the key to promoting spatial network connectivity. In addition, in the policy design and specific implementation process of promoting regional coordination and integration, we should also pay attention to following the principles of separating and classifying government and enterprises, gradually progressing from point to surface, and starting with the easy and then the difficult.
