| The "two-wheel drive" development model of producer services and manufacturing is an important way for industrial transformation and economic growth in developed countries and regions.The shift of my country’s economy from high-speed growth to high-quality development,and the strong correlation between producer services and manufacturing,making the aggregation of producer services to drive manufacturing upgrades become important measures to achieve high-quality development of my country’s economy.As an intermediate input to the manufacturing industry,the producer service industry provides strong intellectual,human and financial support for the upgrading of the manufacturing industry;the producer service industry not only serves the manufacturing industry,but also promotes the upgrading of the manufacturing industry and the agglomeration of the producer service industry Promote manufacturing upgrading through knowledge spillovers and economies of scale.Therefore,it is of theoretical and important practical significance to study the impact of my country’s producer services cluster on manufacturing upgrading.This article takes the agglomeration of producer services and the upgrading of manufacturing industries as the logical starting point and defines the connotation of producer services and upgrading of manufacturing industries.The producer services in this paper mainly include wholesale and retail industries,transportation,warehousing and postal industries.,Information transmission,computer service and software industry,leasing and business service industry,finance industry,scientific research,technical service and geological survey industry;manufacturing upgrade mainly includes industrial structure,industrial efficiency and industrial income.On this basis,the current status of producer service industry and manufacturing industry development is analyzed,the mechanism of the externality of producer service industry’s agglomeration on the upgrading of manufacturing industry is elaborated,and the specialized agglomeration index and diversified agglomeration of producer service industry are measured.Index,using the entropy method to calculate the comprehensive index of manufacturing upgrading.Empirical analysis of the impact of producer service industry agglomeration on manufacturing upgrading,selecting 2006-2017 Chinese provincial panel data,selecting fixed-effect and random-effect models,and through testing found that specialized agglomeration and diversified agglomeration are suitable for fixed effects Model,externality mechanism test is applicable to random effects model.The results of the study found that from the perspective of the national and regional levels,specialized agglomeration played a role in promoting the upgrading of manufacturing industries,while diversified agglomeration did not play a role in promoting the upgrading of manufacturing industries at this stage.The agglomeration of transportation,warehousing and postal services,financial industry,scientific research and technical services in the productive services industry has a positive effect on the upgrading of the manufacturing industry.In addition,fixed asset investment,informatization and economic development There is also a positive role in promoting manufacturing upgrading.Combining the development status and empirical analysis results of my country’s producer service industry and manufacturing industry,it puts forward relevant suggestions on the agglomeration of producer service industry and the upgrading of manufacturing industry... |
