Since the reform and opening up, China's economic level has been continuously improved, and the manufacturing industry, as one of the three major industries, has also achieved rapid development. Since joining the World Trade Organization (WTO), China's foreign trade has also maintained rapid growth for many years. However, in recent years, China's manufacturing industry has been facing the problem of large but not strong. China's foreign trade also urgently needs to solve the problem of large volume but insufficient competitiveness. The covid-19 trade friction has been escalating, the globalization of globalization and the outbreak of the new crown pneumonia have affected the development of the global economy to varying degrees, and the uncertainty of the international environment has increased. Since 2020, China has proposed to gradually form a new development pattern with the domestic cycle as the main body and the domestic and international double cycles promoting each other, so as to cultivate China's new advantages in participating in international cooperation and competition under the new situation. In such a severe environment, to implement the instructions of the CPC Central Committee, realize the high-quality development of domestic industry and foreign trade, promote market integration and improve the quality of export products is the only way to improve China's comprehensive strength. Based on this, this paper explores the impact of market integration on the quality of export products and analyzes the impact channels from the enterprise level, and calculates the level of market integration and the quality index of export products by using China Statistical Yearbook, China industrial enterprise database and China customs database. Based on the existing literature, this paper puts forward the following hypotheses: Based on manufacturing enterprises, (1) there is a nonlinear relationship between market integration and export product quality, which is first enhanced and then inhibited, showing an inverted "U" shape. (2) Market integration will improve the quality of export products by promoting human capital. (3) Market integration will affect the improvement of export product quality by promoting scientific research investment. (4) The impact of market integration on the quality of manufacturing export products is significant in non-state-owned enterprises. (5) the impact of market integration on the quality of manufacturing export products is more significant in eastern and western cities. In order to comprehensively test the impact of the above-mentioned manufacturing industry on the quality of China's manufacturing industry, this paper selects 4596 domestic manufacturing enterprises' benchmark and regression data in 2014, and makes an in-depth analysis of the impact of the above-mentioned manufacturing industry on the quality of China's manufacturing industry, In order to provide some theoretical support for improving the quality of China's export products through market integration.
