Influencing Mechanisms of Energy Utilization on Urban Land Green Utilization Efficiency:A Spatial Econometric Analysis Based on the Yangtze River Economic Belt
Exploring the impacts of energy utilization on urban land green use efficiency is of great practical significance for promoting sustainable regional resource utilization and achieving the transformation of land green use.This study analyzed the influencing mechanism from the perspectives of industrial transfer,technological innovation,and investment expansion.By using the entropy method and the non-desirable output super-efficiency SBM,the energy utilization and urban land green use efficiency in the Yangtze River Economic Belt from 2006 to 2020 were calculated.Furthermore,the spatial Durbin model was employed to analyze the influence of energy utilization on urban land green use efficiency.The results were as follows:(1)During the study period,the overall land green use efficiency in the Yangtze River Economic Belt showed a fluctuating upward trend,with the average efficiency increasing from 0.535 to 0.784.The number of high-efficiency cities not only increased significantly but also showed an apparent trend of concentration and contiguous distribution.(2)There was a spatial interaction between energy utilization and urban land green use efficiency.The direct effect coefficient was 0.136,and the spatial spillover effect coefficient was-0.203.This indicated that energy utilization had a promoting effect on the land green use efficiency of central cities but significantly inhibited the improvement of land green use efficiency in surrounding cities.(3)Policy supply strengthened the direct impact of energy utilization on land green use efficiency,but weakened the negative effect of spatial spillover of energy utilization.Therefore,it was necessary to actively adjust the local industrial structure to reduce production energy consumption.It was also essential to promote the transformation of energy utilization through technological innovation to achieve synchronized improvement of urban land green use efficiency,based on optimizing the energy structure and utilization efficiency.
