Abstract
In order to explore the impact of digital economy on the green development efficiency of the Yangtze River Economic Belt.Based on the SBM-ML index measurement of the green development efficiency of 11 provinces and cities in the Yangtze River Economic Belt during 2011-2020,this paper uses the model of adjustment effect and quantile regression and threshold model to implement an empirical analysis.The research results shows that:The development of digital economy in the Yangtze River Economic Belt has significantly improved the efficiency of green development,and the promotion effect of the middle and upper reaches of the Yangtze River Economic Belt is stronger than that of the lower reaches,which plays a role in bridging the inter-regional green development gap.The urbanization level and urban-rural income gap in the Yangtze River Economic Belt both negatively moderated the impact of digital economy on the efficiency of green development,but there were differences between the two regions in exerting the moderating effect;With the increase of R&D investment,the development of digital economy presents a nonlinear feature of positive marginal increase on green development efficiency.关键词
