| Since joining the World Trade Organization,China’s total foreign trade has grown rapidly with its rich labor and resource advantages,becoming a veritable ’trading power’.However,a large number of scholars have found that the strong growth of China’s export trade is a ’distorted’ over-export caused by the market segmentation strategy.Market segmentation causes enterprises to face high domestic market entry costs,and a large number of enterprises are forced to choose to use international trade to replace domestic trade,thus promoting the increase of export scale.In contrast,the performance of Chinese enterprises in foreign markets does not pursue the construction of their own brands,nor does it improve their own independent R&D and innovation capabilities.Instead,it relies on the development path of low-price competition to expand the quantity,resulting in the overall quality of export products.The level is not high,and it is easy to be ’low-end locked’ in the global value chain for a long time,which is not conducive to China’s transformation from a ’trading power’ to a ’trading power’.Obviously,the foreign trade development model that directly enters foreign markets without relying on the domestic market is not sustainable.At present,China urgently needs to change the mode of foreign trade development and promote the transformation of foreign trade from quantitative expansion to quality improvement.The 20 th National Congress of the Communist Party of China proposed to build a unified national market and accelerate the construction of a strong trading country,relying on China’s superlarge market scale advantages to achieve high-quality trade development.In this context,it is of great significance to systematically examine the impact of market integration on the quality of export products of enterprises,to promote the growth and structural upgrading of manufacturing enterprises,to promote the manufacturing industry to become bigger and stronger,and to promote the construction of a manufacturing power.The research content of this paper is mainly composed of six parts.The first chapter is the introduction,which introduces the research background and significance,innovation and shortcomings of this paper.The second chapter is literature review and research hypothesis.It summarizes the relevant literature on market integration and export product quality at home and abroad,and analyzes the theoretical basis and mechanism of market integration affecting the quality of export products.The third chapter is the analysis of characteristic facts.By drawing charts and tables,it presents the overall development trend of the quality of export products of enterprises and the analysis of the differences among regions,industries,trade modes,provinces and ownership.The fourth chapter is the research design,which introduces the data source,key index construction and model setting.The fifth chapter is the empirical analysis.The empirical test method is used to explore the relationship between market integration and the quality of export products of enterprises.The mechanism of market integration affecting the quality of export products of enterprises is tested,and the heterogeneity analysis is carried out according to the characteristics of enterprises and the external environment.The sixth chapter is the research conclusions and policy recommendations.It summarizes the research conclusions of this paper and puts forward relevant policy recommendations.This paper finds that :(1)Market integration has a significant positive effect on the quality of Chinese enterprises’ export products.(2)The robustness test shows that after replacing the quality of export products and market integration indicators,changing the regression model,reducing the sample size and using instrumental variables,this paper finds that the positive promotion relationship between market integration and the quality of export products is robust.(3)the mechanism test results show that market integration can affect the quality of export products by affecting resource allocation efficiency,product innovation and market competition.(4)The results of heterogeneity test show that there are regional,ownership,trade mode and industry differences in the impact of market integration on the quality of export products.In the future,it is necessary to continuously standardize the behavior of local governments,promote the level of market integration between regional markets,and create a good external market environment for the improvement of the quality of export products. |
