| Service industry,especially producer services,is becoming more and more important in the national economy.As knowledge and technology intensive industry has a strong industry association with manufacturing industry,the development of producer services has an important role in promoting the development of manufacturing industry.In the case of China's manufacturing industry growth,the development of service industry,especially the producer services,has made important contributions to China's economic development.However,there are some problems that producer services is lagging behind and the production service industry and the manufacturing industry association degree is lower in our country.The solution to these problems is in favor of our country to choose the suitable producer service industry agglomeration mode,and promote the production efficiency of manufacturing industry,as well as the further transformation of economic development mode.First,on the basis of the relevant literature,this paper analyzes the production of service industry agglomeration may have the effect of congestion and spillover effects,therefore,the role of producer services agglomeration for manufacturing efficiency may be divided into positive and negative two aspects.On the basis of this,the production service industry agglomeration is differentiated,which can be analyzed from the perspective of professional and diversification agglomeration and then the nonlinear effect mechanism of the agglomeration of producer services on the manufacturing efficiency and the threshold effect mechanism of the impact on the efficiency of the manufacturing industry are analyzed.Secondly,through the static panel model,analyzing the effect of producer service industry agglomeration on manufacturing production efficiency,empirical finding that the effect of producer service industry agglomeration in manufacturing industry is first suppressed and then promoted.In order to measure the agglomeration effect more precisely,dynamic panel model(GMM)is used to eliminate the endogenous problem in the model.From the model results,the system GMM and the differential GMM regression results also supported the finding that the effect of producer service industry agglomeration in manufacturing industry is first suppressed and then promoted.Based on this,we analyze the influence of producer service industry agglomeration on manufacturing labor productivity by using panel threshold model,and empirically verified the influence of two kinds of agglomeration modes on the manufacturing efficiency is limited by the regional scale.And it is also found that the threshold value of the regional scale of the influence of manufacturing industry influenced specialized agglomeration and diversification of producer services is different.Finally,based on the theoretical and empirical analysis,the paper puts forward some policy suggestions on promoting the development of productive service industry and the promotion of labor productivity. |
