Spatial Interaction Spillover Effect of Green Development Efficiency and Industrial Structure Upgrading in the Yellow River Basin
In order to provide reference for green development,industrial structure upgrading and high-quality development in the Yellow River Basin,the super-efficiency SBM model and kernel density estimation method were used to calculate the green development efficiency of 70 prefecture-level cities in the Yellow River Basin from 2006 to 2020,and based on the generalized three-stage space least squares method was used to establish a spatial econometric model of green development efficiency and industrial structure upgrading,and studied the spatial interactive spillover effects of industrial structure upgrading and green development efficiency.The main conclusions are as follows:a)The green development efficiency of the Yellow River Basin shows an overall fluctuating upward trend during the study period.From a spatial per-spective,the regional differences are large at the beginning of the study period,and the regions tend to be consistent at the end of the study period.b)From the overall perspective of the basin,green development efficiency and industrial structure upgrading have mutually reinfor-cing effects.Among them,industrial structure upgrading has a more obvious promotion effect on green development efficiency,and there is a spatial interactive spillover effect between the two.That is,taking prefecture-level cities as the example,the green development efficiency of the sample is positively affected by the green development efficiency of surrounding areas and the upgrading of industrial structure,but the upgrading of industrial structure is negatively affected by the green development efficiency of surrounding areas.c)From a regional perspec-tive,there is regional heterogeneity in the relationship between green development efficiency and industrial structure upgrading.The two pro-mote each other in upstream regions but inhibit each other in middle and lower reaches.The spatial interactive spillover effects of the two on green development efficiency are in the upper,middle and lower reaches areas all show positive trends.d)Green development efficiency is also affected by factors such as the level of economic development,urbanization level,technological innovation,population size,level of o-pening to the outside world,intensity of environmental regulation,government behavior,and basic level of urban transportation.
