Research On The Influence Of Factor Agglomeration On The Upgrading Of Industrial Structure In Jiangsu Province From The Perspective Of Urbanization

In 2019,Jiangsu's urbanization rate reached 70.22%,far higher than China's average level of urbanization.In the study of regional economy,urbanization construction and industrial structure upgrading are important propositions of production and life,and urbanization construction is also the guarantee and important starting point to promote industrial development.Classification according to the three industry at present development characteristics of present industrial structure of jiangsu province "321",but still exists in internal industry development not balanced coordination problems,how to adjust industrial production of the necessary capital,technology and labor elements such as jiangsu province to balance the regional industry structure is a key problem to be solved.This paper closely around "the urbanization perspective elements gathered research on the influence of the upgrading of industrial structure in jiangsu province" this one theme,from the visual angles of new urbanization,with the aid of entropy weight method of new type of urbanization "economy,open,coordination,sharing,green,innovation" the six dimensions measurement to calculate the 2001 to 2018,a new type of urbanization level cities in jiangsu province,At the same time,with the help of location entropy and Cobb-Douglas production function,the comprehensive agglomeration level of production factors such as labor force,capital and technology necessary for industrial production is calculated,and the connotation of industrial structure upgrading is decomposed into two levels: rational development of industrial structure and advanced development of industrial structure.Then we use dynamic panel regression model,panel threshold regression model and spatial Dupin model to explore the non-linear influence mechanism of new urbanization and production factor agglomeration level on industrial structure upgrading.The results show that :1.The development difference of new-type urbanization level in Jiangsu Province is relatively large,and the urbanization level of cities in southern Jiangsu Province is significantly higher than that of cities in northern Jiangsu Province;2.For the rationalization of industrial structure,Jiangsu Province presents a development situation of "balance between north and south,and serious imbalance in the central part",while for the advanced industrial structure,it is more obvious that the regional development pattern of "northeast-southwest" is divided;3.At present,the output elasticity of capital in Jiangsu Province is higher than that of labor and technology,while the agglomeration level of comprehensive factors shows a development pattern of "high in the south and low in the north";4.The analysis results of dynamic panel regression model show that the level of new urbanization and the level of comprehensive factors agglomeration have no significant impact on the upgrading of industrial structure,while the lagging variable of industrial structure upgrading has a significant promoting effect on itself;5.Panel threshold regression model analysis results show that the new urbanization level as the threshold variable,is for both the industrial structure rationalization and high-grade level there are double threshold,differences are the element concentration level to the rationalization of industrial structure development exist inhibitory effect of diminishing marginal,and its influence on the development of the high-level industrial structure effect is from negative to positive.6.The spatial Dubin model for the rationalized development of industrial structure shows that the level of factor agglomeration has a inhibiting spatial spillover effect on the surrounding areas,while the influence of the new urbanization level is not significant.On the basis of the above research conclusions,the paper puts forward policy suggestions to adapt measures to local conditions,coordinate the development of regional industries,promote the transformation of manufacturing and service industries to the middle and high-end,and improve the open trade pattern.
