Research on the Development Level of the Digital Economy in the Yangtze River Delta Region

The Yangtze River Delta is China's most dynamic, open and innovative region, and it plays a strategic role in the country's modernization and opening up. To evaluate the region's digital economy performance and its key drivers, we collect panel data for Shanghai, Jiangsu, Zhejiang and Anhui from 2015 to 2023. First, an entropy weight method is applied to measure the level and the gap of digital economy development in each jurisdiction and to track its evolution. Second, principal component analysis is employed to extract the core factors that shape the regional digital economy. Finally, a coupling coordination model is used to quantify how well the internal components of the digital economy work together.
