Study on Coupling and Coordination of Digital Economy, Ecological Environment and High-Quality Development of Logistics Industry

Based on the panel data of 30 provinces in China from 2011 to 2020, this paper constructs a comprehensive evaluation index system of high-quality development of digital economy, ecological environment and logistics industry, measures the comprehensive evaluation index of each region by entropy method, and explores the temporal and spatial evolution characteristics of the coupling and coordinated development of the three systems by coupling coordination model and Moran index. The results show that: (1) The comprehensive evaluation index of high-quality development of digital economy, ecological environment and logistics industry in China has not changed obviously during the study period, and its spatial distribution is higher in the east than in the middle, and higher in the middle than in the west and northeast. (2) The coupling and coordination degree of China’s three systems is low, and it has been on the verge of imbalance for a long time. Over time, it has evolved into a spatial development pattern of east > middle > west > northeast, and it shows positive spatial autocorrelation characteristics at the provincial level.
