Summary
Summary
Based on the micro data of enterprise geography, this study uses the machine learning Wasserstein distance algorithm, the matrix expansion sinkhorn algorithm and the entropy regularization constraint method to improve the algorithm and solution method, and constructs the industrial spatial correlation index - co index by hypothesis test and Monte Carlo simulation. Based on the measurement results of the level of inter industry copolymerization of the Yangtze River Delta Urban Agglomerations in 2001-2013, this paper uses network analysis method to describe the industrial spatial structure and evolution trend. On the whole, the industrial spatial structure of the Yangtze River Delta has experienced a process of "inverted U-shape" which tends to be close first and then decentralized, and around 2008 is the turning point of the trend change of the spatial structure. From the part of industrial connection, the pillar industries in the Yangtze River Delta show the trend of diversified development, and the pillar industries change to high-quality and high-tech industries, which shows the optimization characteristics of the industrial internal structure in the region. Further, this paper analyzes the differences and evolution trend of industrial spatial structure from the perspective of labor pool, technology spillover and scale effect, and finds that the position of labor-intensive pillar industry in the network is gradually declining, and the position of technology intensive pillar industry and scale economy pillar industry in the network is gradually increasing. Finally, based on the research conclusion, this paper puts forward the corresponding policy suggestions to improve the industrial spatial governance level of the Yangtze River Delta urban agglomeration.
