Research on the Impact of China’s Industrial Structure Upgrading on the Balance of Payments Structure

China's primary industry has experienced slow growth in labor productivity, while the secondary industry, despite having a complete industrial chain, faces challenges such as low value-added products, high energy consumption, and ecological impacts. Although the tertiary industry has witnessed rapid development, there remains a significant gap in terms of standards and quality in the modern service sector. Since China's accession to the WTO, the country's import and export volumes have increased substantially, maintaining a trade surplus in the current account. This study aims to collect continuous data from 1982 to 2021 and utilize comparative analysis and QCA analysis methods to examine the characteristics of China's industrial structure and balance of payments structure. The findings suggest that upgrading the industrial structure can help balance and optimize the structure of the balance of payments.
