The research on the mechanism and spatial-temporal differentiation of the coupling coordination development based on industrial cluster agglomeration

With 31 provinces and cities in Mainland China selected as the research objects, the paper explores the acting mechanism of industrial cluster, urbanization and population cluster, builds a measurement index system for the spatial-temporal coupling characteristics of industrial cluster, urbanization and population agglomeration, and then measures the coupling coordination degrees of industrial agglomeration, urbanization and population agglomeration in provinces since 2000 and researches the spatial-temporal evolution and spatial differentiation characteristics of coupling coordination degree. Research results show: (1) industrial agglomeration, urbanization and population agglomeration have formed a dynamically coordinated relationship with mutual influences, mutual promotion and joint development; (2) the comprehensive development levels of industrial agglomeration, urbanization and population agglomeration in China are rising year by year, but the overall coupling degree and coordination degree of the three are low, but the coupling coordination relationship will improve continuously with time, still showing obvious differences in provinces and the spatial tendency of being "high in the east and low in the west"; (3) the coupling coordination presents a continuous spatial agglomeration state, and the agglomeration intensity is "high on two ends and low in the middle", thus forming the outstanding hot-spot in areas eastern coastal regions and the outstanding cold-spot areas in western regions; (4) the government should promote industrial agglomeration, industrial structure optimization and upgrading and urbanization, and make reasonable planning for population agglomeration degree practically and effectively, to ensure the matching and coordinated development of industrial agglomeration, population agglomeration and urban bearing capacity.
