| With the deepening of international trade,the position of enterprises in the global value chain has been paid more and more attention by various countries.Micro enterprises are one of the important components of the national economy and a driving force in enhancing a country’s trade competitiveness,yet various factors have constrained the domestic value-added rate of Chinese manufacturing enterprises’ exports,which has an impact on their global value chain status.In recent years,the proposal of building a large domestic market has been repeatedly mentioned,and the domestic market segmentation,which originated during China’s economic transition,has gradually received attention from academics.In this paper,we investigate the relationship between the existing domestic market segmentation and the domestic value-added rate of manufacturing firms’ exports,and explore the mechanism and direction of its influence from both theoretical and empirical perspectives.After combing the relevant domestic and foreign literature,this paper,on the basis of studying the overall market,specifically divides the market into commodity market,labor market and capital goods market,and proposes the research hypothesis that the relationship between different types of market segmentation and the domestic value-added rate of manufacturing enterprises’ exports is inverted U-shaped.The relative price method and the price data in the China Statistical Yearbook are used to measure the segmentation index of each market in China,and the domestic value-added rate of manufacturing enterprises’ exports is measured by using the micro-level calculation method and the database of Chinese industrial enterprises and customs database,and the relationship between the two is empirically tested,and the positive to negative turning point of the inverted U-shaped relationship between the segmentation of each market and the domestic value-added rate of manufacturing enterprises’ exports is calculated.Turning point.The endogeneity test,robustness test,influence channel test and heterogeneity analysis were conducted after the benchmark regression to verify the research hypothesis of this paper.This paper finds that(1)there is an inverted U-shaped relationship between domestic market segmentation and domestic value-added rate of manufacturing firms’ exports.When the degree of market segmentation is low,it promotes the increase of domestic value-added rate of manufacturing enterprises’ exports;when the degree of market segmentation exceeds a certain limit,it decreases the domestic value-added rate of manufacturing enterprises’ exports.This relationship holds for the overall market,commodity market,labor market and capital goods market.(2)Cost effect and competition effect are the two mechanisms of the impact of domestic market segmentation on the domestic value-added rate of manufacturing firms’ exports.(3)From the perspective of heterogeneity,the inverted Ushaped relationship is significant under different ownership types,and the turning point shifts to the left under both private and foreign enterprises;under different trade modes,the inverted U-shaped relationship is significant under general trade and mixed trade enterprise types,and the turning points shift to the left and right under general trade and mixed trade respectively;under different regions,the inverted U-shaped relationship is significant under eastern The inverted U-shaped relationship is significant in the eastern part of the country and the turning point is shifted to the right.Based on the full analysis,this paper makes the following recommendations:(1)Promote domestic market reform to lay the foundation for a new dual-cycle pattern.(2)Enhance infrastructure construction to empower the breaking of regional barriers.(3)Guiding the domestic demand-driven export model in the internal cycle to enhance China’s position in the global value chain. |
