基于熵权-TOPSIS的黄河流域农业绿色发展水平评价及其空间差异

Evaluation and spatial difference of agricultural green development level in the Yellow River basin based on entropy weight-TOPSIS

基于黄河流域9个省份2010—2019年的面板数据,从资源节约、环境友好、质量高效和生活保障4个层面选取18个评价指标,运用熵权-TOPSIS模型对黄河流域农业绿色发展水平进行评价,并结合泰尔指数测度其空间差异。结果表明,2010—2019年黄河流域农业绿色发展水平综合得分由0.3284上升至0.4594;组间差异对总体差异的贡献率由54.32%上升至57.59%;质量高效是影响农业绿色发展水平的首要指标。虽然黄河流域农业绿色发展水平整体稳步上升,但区域之间仍存在较大差距,农业绿色发展不平衡不充分问题依然突出。缩小上、中、下游之间的差异、提高农业发展质量是实现黄河流域农业绿色协同发展的重点工作。

Based on the panel data of nine provinces in the Yellow River basin from 2010 to 2019,18 evaluation indexes were select⁃ed from four aspects of resource conservation,environmental friendliness,quality efficiency and livelihood guarantee.The entropy weight-TOPSIS model was used to evaluate the level of agricultural green development in the Yellow River basin,and the spatial dif⁃ference was measured by the Theil index.The results showed that,from 2010 to 2019,the comprehensive score of agricultural green development level in the Yellow River basin increased from 0.3284 to 0.4594;the contribution rate of inter-group difference to the overall difference increased from 54.32%to 57.59%;quality efficiency was the primary indicator affecting the level of agricultural green development.Although the overall level of agricultural green development in the Yellow River basin had steadily increased,there was still a large gap between regions,and the problem of unbalanced and insufficient agricultural green development was still prominent.Reducing the differences between the upstream,midstream and downstream and improving the quality of agricultural devel⁃opment were the key tasks to realize the green coordinated development of agriculture in the Yellow River basin.
