摘要:  探究能源利用对城市土地利用绿色利用效率的影响,对推动区域资源可持续利用和实现土地绿色利用转型等具有重要现实意义。研究从产业转移、技术创新及投资扩张等角度分析两者的影响机制,借助熵值法和非期望产出超效率SBM模型测算2006~2020年长江经济带能源利用与城市土地绿色利用效率的基础上,利用空间杜宾模型分析了能源利用对城市土地绿色利用效率的影响。结果显示:(1)研究期内长江经济带土地绿色利用效率整体呈波动上升趋势,平均效率由0.535上升到0.784,不仅高值城市数量增幅趋势显著,且集中连片分布趋势明显;(2)能源利用对城市土地绿色利用效率存在空间交互作用,直接效应系数为0.136、空间溢出效应系数为-0.203,表明能源利用对中心城市的土地绿色利用效率有推动作用,但其显著抑制了周边城市土地绿色利用效率的提升;(3)政策供给强化了能源利用对土地绿色利用效率的直接影响,同时弱化了能源利用空间溢出效应的负向作用。因此,要积极调整本地区产业结构以降低生产能耗,通过技术创新推动区域能源利用转型,在优化区域能源结构与利用效率的基础上实现区域内城市土地绿色利用效率的同步跃迁。

Abstract: 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.
