The Impact Of Agglomeration Of Producer Service Industry On Upgrade Of Manufacturing Industry In China

The manufacturing industry occupies an important position in the national economy,and it symbolizes the international competitiveness of a country and the comprehensive strength of the country.The development of a country's manufacturing industry determines its status of international division of labor in the economic globalization.However,in recent years,in the context of global economic crisis,international trade protectionism,the rise of resources and price volatility,and the rapid rise in labor costs in China,the serious development of manufacturing industry is worse,and achieving the overall transformation and upgrade is manufacturing industry's urgent need.Solving these serious problems depends on the development of the productive service industry.How to effectively play the role of producer services in the transformation and upgrade of manufacturing industry is an important issue to build the common value chain of manufacturing and producer services.Based on the relevant theoretical basis and realistic background,this paper discusses the research about the impact of agglomeration of producer services on the upgrade of manufacturing.Based on the theoretical analysis and the literature review,beginning with the present situation of China's agglomeration of producer services and upgrade of the manufacturing industry,gradually in-depth investigate the mechanism of the effect of agglomeration of producer services on upgrade of the manufacturing industry,the association of agglomeration of producer services and upgrade of manufacturing industry,the effect,the threshold effect and the spatial spillover effect of agglomeration of producer services on upgrade of the manufacturing industry,which are conducive to provide a new thinking to the effect of the agglomeration of producer services on the upgrade of the manufacturing industry.Based on the relevant theoretical basis of instustrial agglometation and industrial upgrade,the paper uses gray correlation analysis,panel regression,panel threshold model and spatial panel model to measure and analyse the effect of agglomeration of producer services on upgrade of the manufacturing industry.The main contents and conclusions of this paper are as follows:1.The present situation of agglomeration of producer services and upgrade of manufacturing industry in China is analyzed.The specialized and diversified agglomeration level of producer services among 30 provinces in the whole country during 2006~2015 were measured,and the current situation of manufacturing upgrade was analyzed.At the same time,the regional differences and time series changes of the agglomeration level of productive service industry and the upgrade of manufacturing industry are analyzed respectively.It is found that the trend of specialized clustering is obvious,while the trend of diversified clustering is not obvious.At the same time,there are obvious regional differences between specialized and diversified clustering.Generally speaking,the level of pecialized and diversified clustering of producer services in the eastern region is higher than that in the western regions,and the central region is the lowest.The upgrade index of manufacturing industry has a rising trend in terms of labor productivity during the period of 2006~2015.Meanwhile,there are still some regional differences.The eastern region's manufacturing labor productivity is higher than that of the central region,and the western region is the lowest.2.The influence mechanism of the agglomeration of producer service industry on the upgrade of manufacturing industry is analyzed,and the mathematical model is further discussed.The specialized agglomeration of producer services promotes the upgrade of the manufacturing industry mainly through economies of scale,competition,specialization and knowledge spillover effect;the diversified agglomeration of producer services promotes the upgrade of the manufacturing industry mainly through economies of scale,cooperation and knowledge spillover effect.The mathematical model from the perspective of knowledge spillovers and economies of scale found that there is an obvious functional relationship between producer services agglomeration and upgrade of the manufacturing industry.The higher the level of specialized and diversified agglomeration of producer services,the unit production cost of manufacturing industry is lower and the production efficiency is higher,which can promote the upgrade of the manufacturing industry better.3.There is a significant correlation between the agglomeration of productive service industry and the upgrade of manufacturing industry in China.Based on the grey correlation analysis,the results show that the correlation between the agglomeration of productive services and the upgrade of manufacturing industry is higher than 0.60.Moreover,there are some regional differences in correlation degree.The specialized agglomeration of producer services in eastern China is most closely related to the upgrade of manufacturing industry,while the diversified agglomeration of producer services in the central region is most closely related to the upgrade of manufacturing industry.4.The impact of the agglomeration of productive service industry on the upgrade of China's manufacturing industry is studied.Based on ordinary least squares estimation,fixed effect model,random effect model,it is found that the specialized agglomeration of producer service industry has a strong role in promoting the upgrade of in 232 cities of China's manufacturing industry.At the same time,the specialized agglomeration of producer service industry has obvious regional differences in promoting the upgrade of manufacturing industry in China.The effect on the upgrade of manufacturing industry in the eastern region is strongest,followed by the western region,and the central region is the weakest.The study also found that the diversified agglomeration of producer services had a weaker obstacle to the upgrade of manufacturing industry in China,and showed obvious regional differences.The West has the most hindered effect,followed by the eastern part,and the central region is the weakest.5.The threshold effect of the impact of the agglomeration of productive service industry on the upgrade of China's manufacturing industry is studied.Using panel threshold regression method,the author analyzes the threshold effect of producer services agglomeration on manufacturing upgrade in 232 cities of China.It is found that the influence of producer services agglomeration on manufacturing upgrade is nonlinear,and there is a single threshold effect on the impact of specialized and diversified agglomeration of producer services on manufacturing upgrade.232 city samples were divided in accordance with the eastern,central and western regions,and then the threshold effect test found that the effect of specialized agglomeration of producer services on manufacturing upgrade in the central and western regions have a threshold effect,and there are some regional differences in threshold effect,but the threshold effect does not exist in the east region;The effect of diversified agglomeration of producer services on manufacturing upgrade in the eastern and central regions all have a single threshold effect,but the threshold effect does not exist in the west region.6.The spatial spillover effect of the agglomeration of productive service industry on the upgrade of China's manufacturing industry is studied.Using the spatial panel model,the author empirically analyzes the direct effect of services agglomeration on manufacturing upgrade,and meanwhile analyzes the spatial spillover effect of producer services agglomeration on manufacturing upgrade.It is found that the specialized agglomeration of producer services has a significant positive spatial spillover effect on the manufacturing upgrade,and there is no significant spatial spillover effect of the diversified agglomeration of producer services on manufacturing upgrade.At the same time,the spatial spillover effect has significant regional differences,the specialized agglomeration of producer services in eastern and central regions has a significant positive spatial spillover effect on the manufacturing upgrade,while in the western region it has no spatial spillover effects;In eastern,the diversified agglomeration of producer services has a significant negative spatial spillover effect on the manufacturing upgrade,while in the central and western region,it has no spatial spillover effects.To sum up,the conclusions of this paper enrich the existing research results,provide some empirical supports for related theory,and also can help each region promote productive service industry cluster development and upgrade of the manufacturing industry,build agglomeration of producer services to be more conducive to the upgrade of the manufacturing industry according to the economic characteristics.
