摘要
土地生态效率反映了经济发展与生态环境的投入和产出关系,其效率的高低对区域高质量发展有着重要的影响。采用超效率SBM模型测算2010年、2015年、2020年贵州省县域土地生态效率,通过空间杜宾模型对土地生态效率时空差异及其影响因素进行分析。研究结论如下:贵州省土地生态效率处于中等效率水平,整体呈南北高、中部低的条带状空间分布规律;经济发展水平、政府干预和教育水平对土地生态效率表现出正向直接效应,区域投资水平则表现为负向直接效应;产业结构、区域投资水平和环境规制对土地生态效率具有负向溢出效应。
Land eco-efficiency reflects the input-output relationship between economic development and ecological environment, which has an important impact on regional high-quality development. The Super-efficient SBM Model was used to measure the land eco-efficiency at the county level in Guizhou Province in 2010, 2015and 2020. Thereafter, the Spatial Durbin Model was used to analyze the spatial-temporal differences of land ecoefficiency as well as the relevant influencing factors. The conclusions are as follows:(1) Land eco-efficiency in Guizhou Province is at a medium efficiency level, with an overall strip-like spatial distribution pattern of higher in the north and south while that lower in the center.(2) Economic development level, government intervention and education level show a positive direct effect on land eco-efficiency, while regional investment level shows a negative direct effect.(3) Industrial structure, regional investment level and environmental regulation have negative spillover effects on land eco-efficiency.
