Research On The Impact Mechanism Of Industrial Agglomeration For TFP Of Productive Services From The Perspective Of Spatial

Under the situation of Supply-side structural reform,productive services has become a strategic commanding point of global industry competition.But producer services is facing the problems such as irrational structure?low level and regional uncoordinated,which put forwards new requirements and new challenges for promoting the rapid development of the industry and move towards to innovative and active economy.TFP is the embodiment of the level of industrial development.Which involves the effect of the Supply-side reform and even the development of the whole national economy.In order to improve the TFP of the productive services,we need to grasp the development mechanism of the productive services fully.Based on the theory of spatial economics and heterogeneity of TFP,this paper discusses the upgrading mechanism of industrial agglomeration to TFP.This paper analyzes the spatial spillover that industrial agglomeration for TFP of productive services and the impact in different stages of agglomeration,it can help identify the development mechanism and clarify the position of industrial agglomeration in its development.Also providing policy basis for the accurate implementation of industrial policy and regional coordinated and stable development.It is an important breakthrough in seeking another economic growth point.This paper combs the role mechanism of industrial agglomeration for TFP of productive services based on the literatures,and use the SDM to carry out an empirical test.First of all,reflect the realistic problem based on the research background,refine the purpose of the study and put forward the research method on the basis of the analysis of the literature.Secondly,uses theory to analyze the mechanism which productive services,manufacturing and the synergistic agglomeration of them to the TFP of productive services.Finally,uses the spatial econometric model to carry out an empirical test.The first part of the empirical study from the two dimensions of time and region,first the nuclear density of TFP in the productive services industry is estimated and the dynamic evolution characteristics of TFP are obtained.Then structures area comprehensive capability index evaluation system,uses the Tel index to verify the regional difference of TFP;The second part of empirical study explores the spatial pattern and distribution pattern of TFP of with the help of ESDA,which confirms the spatial correlation of TFP.Secondly,uses SDM to explore the spatial spillover of industrial agglomeration to TFP and the different effect on the evolution of time.Then uses the robustness test as quantile regression.Finally,put forward the summaries and suggestions.The results of the study show that:(1)There is an obvious regional heterogeneity in TFP of productive services.Because of the uncoordinated economic development of the region,the development of TFP has been differentiated.The government optimize the layout of the industrial structure,implementing the strategy of differential development.(2)There is an obvious spatial correlation in TFP of productive services.TFP in those regions with close geographical distance or similar economic development are strongly associated with development.The government should encourage regional communicate and cooperate,promote technology diffusion and knowledge spillover.(3)The influence of industrial agglomeration on the TFP of local productive service industry has a phased law.At the early stage of agglomeration,congestion is dominant,the agglomeration effect is dominant after a certain stage.Industrial Synergy gathering can promote TFP.The government should encourage industrial synergy,create a good industrial agglomeration environment,promote the intensive and standardized of industrial agglomeration.The spatial spillover effect of industrial agglomeration on TFP is positive in the early stage of agglomeration,as the degree of agglomeration deepens,the "crowding out effect" has hindered the promotion of TFP in other provinces.The government should make full use of regional geographical advantages and economic development characteristics.Thus maximizing the spatial spillover effect of industrial agglomeration.
