摘要
采用非径向的SBM-DEA模型对2011-2017年黄河流域各省份的生态福利绩效进行测算评价,运用Moran散点图和LISA图着重考察其空间差异性及演变,然后使用空间计量模型对黄河流域生态福利绩效的影响因素进行检验。结果显示:(1)黄河流域整体生态福利绩效综合水平小于1,未能实现DEA有效,且呈现出“中部最高、东部和西部次之”“下游最高、上游和中游次之”的态势。(2)黄河流域生态福利绩效水平呈现出较高的局部空间异质性,存在明显的空间差异且空间依赖性和空间效应随时间的推移而发生变化。(3)黄河流域生态福利绩效主要受到技术水平、城镇化、医疗水平、经济外向性以及社会性支出等因素的影响。
The non-radial SBM-DEA model was used to evaluate the ecological well-being performance(EWP)in the Yellow River region of China from 2011 to 2017 in this paper.Moran scatter plot and LISA chart were used to investigate the spatial differences and evolution of the EWP,and then we used spatial econometric model to test the influencing factors of EWP in the Yellow River region.The results are as follows:(1)The comprehensive level of EWP of the Yellow River region is less than 1,which cannot achieve DEA efficiency,and shows the trend of“the highest in the middle,followed by the east and west”,“the highest in the downstream area,and the second in the upstream and midstream areas”;(2)The comprehensive level of EWP of the Yellow River region has high local spatial heterogeneity and obvious spatial differences,and the spatial dependence and spatial effect are changed by time;(3)The main influencing factors of EWP in the Yellow River region include technical level,urbanization,medical level,economic export-oriented and social expenditure.
