| 摘 要： | 减贫成效评估是近年来国际减贫战略研究中的热点议题,也是中国未来扩展减贫深度、提高减贫质量所面临的关键问题。论文基于“两不愁、三保障”标准,构建涵盖经济、人口、社会和绿色4个维度12项指标的减贫成效评估指标体系,利用熵权法与模糊集方法揭示长江经济带126个地级市域减贫成效状况,引入空间自相关理论解析长江经济带减贫成效的空间分异及演化特征。结果表明:① 2011—2017年间长江经济带整体减贫成效显著,区域间存在明显空间差异,上游地区市域减贫提升潜力较大;② 研究期内市域Moran's I均大于0且逐年上升,市域减贫成效存在空间正相关性且集聚特征逐年增强;③ 研究期内减贫成效指数的LISA值存在区域差异,上、中游地区局域空间自相关较为显著,尤其在集中连片贫困区呈现“连块集聚”的关联特征。研究成果可为当前推动长江经济带可持续减贫,统筹区域经济、社会和生态协调发展提供参考。 |

| Abstract: | Evaluation of the effectiveness of poverty reduction is a hot topic in international poverty reduction strategy research in recent years, and it is also a key issue for China to deepen and improve the quality of poverty reduction in the future. Based on the criteria of "rural poor people have no worry about food and clothing and have access to compulsory education, basic medical services, and safe housing", this study constructed an index system for evaluating the effectiveness of poverty reduction, which covers economic, demographic, social, and green development dimensions that include 12 indexes. Entropy weight and fuzzy set methods were used to reveal the effectiveness of poverty reduction in 126 cities of the Yangtze River Economic Belt, and the spatial autocorrelation theory was introduced to analyze the spatial differentiation and evolution characteristics of poverty reduction effectiveness in the region. The results show that: 1) During 2011 and 2017, the Yangtze River Economic Belt as a whole achieved remarkable results in poverty reduction, but there were obvious spatial differences among different areas, and there was great potential for poverty reduction and improvement in the upper reaches of the Yangtze River Economic Belt. 2) During the study period, the Moran's I of the cities was greater than 0 and increased year by year, the effectiveness of poverty reduction in the cities showed a positive spatial correlation and the agglomeration characteristics steadily enhanced. 3) There were regional differences in the local indicators of spatial association (LISA) value of the poverty reduction effectiveness index during the study period, and the local spatial autocorrelation between the upper and the middle reaches was more significant. Especially in the concentrated contiguous severe poverty areas, it showed the correlation characteristic of continuous agglomeration. The research results can provide a reference for promoting sustainable poverty reduction and coordinating regional economic, social, and ecological developments in the Yangtze River Economic Belt. |
