| Currently,the economy of China has transitioned from high speed to high quality.The manufacturing industry is the ballast of a country’s economy.While increasing the total amount,we should steadily achieve high-quality development.High-tech manufacturing industry is an important part of manufacturing industry,which is closely related to the high-quality development of manufacturing industry.As an intermediate service,the industry of producer service has become an important part of the production,R & D and other processes of high-tech manufacturing industry.Industrial agglomeration is an important means of industrial upgrading and transformation.After long-term development,it has gradually shifted from single industrial agglomeration to collaborative agglomeration of related industries.Collaborative agglomeration can produce economies of scale,form benign complementarity among multiple related industries,effectively obtain high profits and high added value in the industrial value chain,and improve the efficiency of resource allocation and utilization,Then it has a positive effect on the industry’s competitiveness of the export,and the collaborative agglomeration of producer services and high-tech manufacturing industry is a representative one.This paper explores the impact of the collaborative agglomeration of producer services and high-tech manufacturing on the export competitiveness of high-tech manufacturing.On the one hand,it is conducive to the development of producer services and high-tech manufacturing,on the other hand,it improves the export competitiveness of high-tech manufacturing.This paper selects 30 provinces and regions in China as the research object,combines theory with demonstration,and studies the effect of collaborative agglomeration of producer services and high-tech manufacturing on the export competitiveness of high-tech manufacturing.This paper adopts the method of location entropy to measure the agglomeration level of producer services and high-tech manufacturing,and then constructs the collaborative agglomeration index as the evaluation index of the collaborative agglomeration degree of the two industries.The empirical part adopts the provincial panel data from 2009 to 2018,introduces control variables,constructs an econometric model with and without the square term of the collaborative agglomeration index of producer services and high-tech manufacturing,and uses the fixed effect model to test the relationship between the collaborative agglomeration level of the two industries and the export competitiveness of high-tech manufacturing.The results show that the collaborative agglomeration of producer services and high-tech manufacturing can significantly promote the export competitiveness of high-tech manufacturing,and has the characteristics of regional differences in the eastern,central and western regions;There is an inverted "U" relationship between the collaborative agglomeration of producer services and hightech manufacturing and the export competitiveness of high-tech manufacturing;Regional economic development and human capital level can significantly enhance the export competitiveness of high-tech manufacturing industry and promote the export trade development of high-tech manufacturing industry.Based on the research results,this paper also puts forward some relevant policy suggestions on how to improve the export trade capacity of high-tech manufacturing industry and promote the high-quality development of manufacturing industry and China’s economy. |
