Theoretical Analysis And Empirical Study On Spatial Agglomeration And Distribution Evolution Of Producer Services

In the process of the transformation and upgrading of manufacturing industry,producer service industry will play an important role as an intermediate investment industry.In recent years,with the rise of producer services,the industrial layout of the Yangtze River Delta has undergone certain changes.The spatial pattern of producer services in the Yangtze River Delta is closely related to the agglomeration of producer services.Producer services will inject new vitality into the development of the Yangtze River Delta region,and grasp the balance between producer services agglomeration and producer services spatial pattern,which is conducive to the steady development of the Yangtze River Delta region.Based on this,this paper based on industrial economics,spatial economics,geography,economics and the theory and methods of production service industry agglomeration in the Yangtze River delta evolution paths of the spatial pattern of theoretical research and empirical test.Specifically,firstly,the Gini coefficient of Krugman is used to measure the agglomeration of producer services,and the types of agglomeration are divided into stationary,ascending,descending,U and inverted U.Secondly,the RGrowth industry distribution of producer services spatial pattern of specific measures,and in-depth study of influencing factors of producer services spatial pattern evolution,thus further study of producer service industry agglomeration in the Yangtze River delta evolution paths of its spatial pattern.Finally,based on the perspective of spatial economics,the construction of productive service industry spatial pattern from the theoretical model,based on the perspective of econometrics,econometric model construction of productive service industry spatial pattern,and the empirical test,draw relevant conclusions.The main conclusions of this paper are as follows:(1)The productive service industry agglomeration in the Yangtze River Delta region presents obvious regional differentiation and different agglomeration trends,and the overall development trend remains steady;(2)The spatial distribution of the productive service industry in the Yangtze River Delta region is transferred between cities;(3)Influencing factors of producer services spatial pattern evolution in the Yangtze River Delta region,the agglomeration of producer services,and protection of local economic development is promoted,and the foreign trade,technological progress has inhibitory effect;(4)The Yangtze River Delta region of producer service agglomeration on the spatial distribution evolution mechanism for producer services agglomeration area function extension of producer services to promote the Yangtze River Delta region,the transformation and upgrading of producer service industry of the city spatial development strategy in Yangtze River Delta city group,to promote the development of productive service industry and manufacturing industry spatial distribution of interaction strengthen the industrial spatial distribution in Yangtze River Delta region extension,employment structure and spatial distribution of the differentiation of the Yangtze River Delta region production service industry spatial restructuring and transportation space adjustment in Yangtze River Delta region accelerated production service industry spatial distribution evolution of five parts..In order to optimize the development of producer services in the Yangtze River Delta region,the overall industrial layout of the Yangtze River Delta region should be controlled macroscopically.This paper puts forward the following specific policy recommendations from six aspects: producer services agglomeration,foreign trade,economic development,technological progress,local protection and natural geography.(1)Improve the concentration of producer services;(2)Rational use of foreign trade resources;(3)Perfecting the economic development plan of the Yangtze River Delta region;(4)Rational use of technical progress;(5)Industrial planning for the Yangtze River Delta;(6)Take advantage of physical geography.
