The Yangtze River Delta is the region with the earliest start, the best foundation and the highest degree of regional integration development in China. In recent years, the integration of the Yangtze River Delta has made positive progress. However, there are still some deep-seated problems in the deepening of the integration of the Yangtze River Delta. The most fundamental thing to promote the higher-quality integrated development of the Yangtze River Delta is to establish a unified, open, competitive and orderly modern market system.First, establish a regional unified market. The basic requirements of a unified regional market are to unify policies between regions, reduce the transaction cost of factor flow and expand the market allocation space of enterprises. With these efforts, we can realize mutual access to products, free flow of production factors, and cross-regional operations of enterprises.Second, establish a regional open market. It is necessary to break new ground in pursuing all-dimensional, multi-tiered and all-sectoral opening-up.Third, establish a regional competitive market. Sufficient market competition is the micro foundation for the formation of high-quality integrated development of the Yangtze River Delta.Fourth, establish an orderly regional market. The goal of market order construction in the Yangtze River Delta is to establish a fair market competition environment to achieve the efficiency goal of resource allocation, and to standardize the order of competition to achieve social fairness.
