Measurement,spatial-temporal evolution and regional differences in the green transformation efficiency of four types of resource-based cities in China
Enhancing resource cities'green transformation at a faster pace to boost productivity is the path to achieving superior e-conomic growth in the new era.Based on the panel data of 110 resource cities in China,this paper investigated the spatial-temporal e-volution characteristics and regional differences of the green transition efficiency of resource cities by comprehensively adopting the Su-per-SBM model,kernel density estimation,and Dagum's Gini coefficient.The results indicated that:①Overall,resource-based cities'green transition efficiency showed a fluctuating downward trend,and its annual average showed a fluctuating development of decline-rise-decline-rise during the study period.The overall decline was not significant,but the number of cities in high-efficiency areas had decreased significantly.②The efficiency of each type of resource-based green transition had a similar evolutionary trend,with the size of regeneration＞maturity＞growth＞decline.③Regional differences in the efficiency of green transition in resource-based cities showed a growing trend during the study period,and the size of intra-regional differences manifested itself in the form of mature＞growing＞regenerating＞declining,with hypervariable density and intra-regional differences being the main reasons for the regional differences.
