The Yangtze River Economic Belt is an important strategic support for the development of national economy.Choosing a green development path is the only way to promote sustainable development.This paper es-tablishes an evaluation index system based on production,living and ecology,and evaluates the green devel-opment level of 130 cities in the study area from 2010 to 2019 by using entropy weight method.Based on the global and local Moran'I indices,the spatial correlation pattern of green development level at 2010,2015 and 2019 in the study area was calculated,and the influencing factors of green development level in the study area were analyzed by using spatial Dubin model.The following conclusions are drawn from the study:The first,from the perspective of time distribution,the trend of green development in the study area is N-type fluctuating growth trend;The Second,from the perspective of spatial distribution characteristics,the green development status of the study area is lower reaches>middle reaches>upper reaches.Within provinces and cities,the development trend in the east is stronger than that in the west,and the urban agglomeration in the Yangtze River Delta presents a circle layer structure.The third,from the perspective of spatial dif-ference analysis,both intra-regional and inter-regional differences show a decreasing trend,and the over-all green development difference of the Yangtze River Economic Belt shows a"Λ"-type fluctuation.The fourth from the perspective of spatial autocorrelation analysis,most of moran points are concentrated in the first and third quadrants(high-high aggregation,low-low aggregation),and the inter-regional aggregation effect gradually increases and spreads outward.The Fifth,the results of spatial Dubin model show that economic de-velopment,scientific and technological innovation and industrial structure have a positive impact on the green development of the Yangtze River Economic Belt,environmental regulation has a negative impact on the green development,and education investment and opening up have no significant impact on the green develop-ment.Based on the analysis results,this paper puts forward four suggestions:pay attention to the overall nature of green development,promote the upgrading of industrial structure,increase technological input and strengthen government regulation.
