The Impact Of The Agglomeration Of Productive Services On The Upgrading Of Manufacturing Industry In China

Manufacturing industry is the main body of the national economy,the foundation of the founding of the country,the tool of revitalizing the country,and the guarantee of a powerful country.Our country is a big manufacturing country,and the output of various industries ranks first in the world.The vigorous development of manufacturing industry has injected fresh vitality into our economy and promoted our economic development.However,China's manufacturing industry structure is relatively single,the development mode is relatively backward,and there is a clear gap with developed countries,and China's manufacturing industry is still facing the embarrassment of "big but not strong".The upgrading of manufacturing industry is imperative.Productive service industry,as the intermediate input of manufacturing industry,is closely related to manufacturing industry.Productive service industry is separated from manufacturing industry,which in turn affects the development of manufacturing industry.In recent years,there has been an obvious trend of agglomeration of producer services in space.Will the agglomeration of producer services have an impact on manufacturing industry? Based on this,this paper studies the non-linear relationship between the agglomeration of productive services and manufacturing industry.Firstly,this paper introduces the concepts and connotations of producer services and manufacturing industry in detail,and classifies them in detail.It explores the impact mechanism of producer services agglomeration on manufacturing upgrading from four aspects: scale economy effect,specialization effect,competition effect and knowledge spillover effect.At the same time,it focuses on the analysis of the current situation and problems of the development of producer services and manufacturing industry in China.At the same time,it compares horizontally and vertically in order to better understand the development level of producer services and manufacturing industry in China,and to do a good job in the following empirical analysis and policy recommendations.Secondly,based on the panel data of 30 provinces,cities and autonomous regions from2004 to 2016,the agglomeration level of producer services at provincial level in China is measured by location entropy,and the agglomeration degree of producer services in the whole country and in the eastern,central and western regions is comparatively analyzed.Based on the results of Hossmann test,a fixed effect model is selected and a threshold regression model is established to study the non-linear relationship between the agglomeration of producer services and the upgrading of manufacturing industry in China and the eastern,central and Western regions.This paper draws the following conclusions:(1)The development of producer services in China is unbalanced,and the agglomeration level of producer services in eastern China is much higher than that in central and Western China.(2)The agglomeration level of producer services,human capital,material capital,transportation infrastructure,informationization degree and government expenditure all have a positive effect on the upgrading of manufacturing industry,but the effect intensity is different.(3)The agglomeration level of different industries has different impacts onmanufacturing industry.Rental and business services are not conducive to the upgrading of manufacturing industry.The other five industries have a positive effect on the upgrading of manufacturing industry.From strong to weak,they are financial industry,wholesale and retail industry,scientific research,technical services and geological prospecting industry,information transmission,computer service and soft industry.Parts industry,transportation,warehousing and postal industry.(4)The whole country passed the single-threshold test,the eastern and central areas passed the double-threshold test,and the western areas passed the single-threshold test.(5)Regardless of the level of the agglomeration of producer services,whether in the whole country or in the eastern,western and Eastern regions,the agglomeration of producer services will promote the transformation and upgrading of manufacturing industry,but with different intensity.At the national level,with the improvement of the agglomeration level of producer services,the impact coefficient shows a decreasing trend,that is,the promotion effect has a decreasing trend.With the improvement of the agglomeration level of producer services,the promotion role of the ministries and regions to the upgrading of manufacturing industry first strengthens and then weakens.With the improvement of the agglomeration level of producer services in the central region,the promotion effect on the upgrading of manufacturing industry first weakens and then strengthens.With the improvement of the agglomeration level of producer services in the western region,the promotion of manufacturing upgrading is gradually enhanced.Finally,in order to make the agglomeration of producer services better promote the upgrading and coordinated development of manufacturing industry,based on the results of empirical research,some suggestions are put forward: actively implement the talentstrategy,give full play to the agglomeration effect of producer services;improve the correlation between producer services and manufacturing industry,promote coordinated development;vigorously develop manufacturing industry,improve core competitiveness;and strengthen effective competition.Reduce vicious competition,promote exchanges and cooperation among enterprises,promote high-quality development of manufacturing industry,and transform to intellectualization.
