随着中国脱贫攻坚的顺利完成,全面推进共同富裕逐渐成为实现中国式现代化的重要任务.本研究从富裕度、共享度、共同度、可持续性维度构建共同富裕评价指标体系,借助熵权-TOPSIS法、泰尔指数、多尺度地理加权回归等方法对武陵山区共同富裕水平的时空演化及影响因素进行分析.结果表明 2011-2021 年间武陵山区共同富裕水平较低但呈现缓慢上升的趋势.武陵山区共同富裕的空间发展格局表现出"北快南慢、东快西慢"的演进趋势,并且核心县域对周边县域产生了正向溢出效应.武陵山区共同富裕水平的差距表现为"微弱波动、小幅下降"的趋势,湖南片区内部差距是山区总体差距的主要来源.各个因素在不同时期内对武陵山区共同富裕水平的影响强度和波动方向不同.其中人均 GDP 的影响作用最为显著.研究为欠发达地区有效衔接乡村振兴、实现共同富裕提供理论依据和科学参考.
The Spatio-temporal Evolution and Influencing Factors of Common Prosperity Level in the Wuling Mountain Area
As China successfully won the tough battle against poverty,advancing common prosperity on all fronts has gradually become an important task in realizing Chinese modernization.The evaluation index system for common prosperity is constructed of four dimensions of"affluence,sharing,commonality,and sustainability",and the Entropy weight-TOPSIS method,Theil index,and Multiscale geographically weighted regression are applied to analyzing the spatio-temporal evolution and influencing factors of common prosperity level in the Wuling Mountain area.The results show that the level of common prosperity in the Wuling Mountain area was low but slowly in-creased from 2011 to 2021.The spatial development pattern of common prosperity in the Wuling Mountain area shows an evolutionary trend of being"fast in the north and east,and slow in the south and west".The core counties have a positive spillover effect on the neighboring counties.The overall gap in the level of common prosperity in the Wuling Mountain area displays a trend of"weakly fluctuating and slightly declining",with the main source of de-velopment differences within the Hunan region.Each factor shows various impact intensit on the level of common prosperity in the Wuling Mountain area and its fluctuation directions at different times.Among these factors,GDP per capita has the strongest impact and always plays a positive role.The conclusions of this study can provide a theoretical basis and scientific reference for the less developed regions to effectively articulate rural revitalization and realize common prosperity.
