The Yangtze River Delta (YRD) is one of the regions with the most dynamic economy, the highest degree of openness, and the strongest innovation capability in China, possessing crucial factor markets, infrastructure development, and population resources. With the progress of Chinas reform and opening-up policies and economic development, the YRD has achieved remarkable economic growth and social progress over the past few decades. Research on the economic and social integration of the YRD aims to deeply understand the development status of factors, infrastructure development, and trade within the region, and to explore how to address issues of inter-regional cooperation, coordination, and integration in the corresponding direction. Comprehensive research methods, including desk research, quantitative analysis, and qualitative analysis, are need to adopted in this research. This paper primarily proves through data collection that the research on regional factors, infrastructure development, and trade integration in the YRD is of great significance for promoting regional synergetic development, optimizing resource allocation, and enhancing overall competitiveness.
