| 摘 要： | 从地市空间尺度出发，应用空间聚类分析方法和地理加权回归模型，研究了2006、2011和2016年湘渝川滇黔桂111个地市城镇化减贫效应的空间异质性及其时空演变趋势。结果表明：① 湘渝川滇黔桂地市城镇化减贫效应存在明显的空间异质性，其中，人口城镇化率提升对农民收入的影响总体逐步增强，且影响系数最高值区域总体稳定在湖南境内的中东部地市；② 产业城镇化总体具有益贫性，但在部分地区表现为抑制农民增收，其总体正向影响变大的同时差异性也随之扩大。在空间上，产业城镇化的减贫效应最低值区域从湖南、广西境内集中分布及其它省域分散分布向湖南东南部和广西东北部收缩，人口城镇化减贫效应低值区域和产业城镇化的高值区域基本重合；③ 土地城镇化对农民收入影响有正有负，但回归系数的均值一直为负，总体上抑制农民增收，其减贫效应空间上呈现差异扩大趋势，其最高值由四川北部及东北部、重庆东北部、广西东南部等地区逐步向广西境内集中，总体上呈现“南高北低”分布格局；④ 城镇化质量对农民收入均有显著的正向影响，且总体减贫效应逐步提升，但这一效应呈现出倒“U”型特征。在空间上，湖南地市城镇化质量减贫效应强于其他省份地市。据此，提出加快推进人口城镇化进程、合理优化二三产业结构、制定科学的征地补偿制度和因地制宜地促进城镇化高质量发展的建议。 |

| Abstract: | Based on the spatial scale of prefecture level cities, spatial clustering analysis method and geographically weighted regression model are applied to studying the spatial heterogeneity of poverty reduction effect of urbanization and the trends of spatiotemporal evolution with the data from 111 prefecture level cities of Hunan, Chongqing, Sichuan, Yunnan, Guizhou and Guangxi in 2006, 2011 and 2016. The results show that: 1) There is obviously spatial heterogeneity in poverty reduction effect of urbanization in Hunan, Chongqing, Sichuan, Yunnan, Guizhou and Guangxi. Among them, the increase of population urbanization rate has gradually increased the overall impact to farmers’ income, and the high impact coefficients are mainly concentrated in the central and western Hunan. 2) Industrial urbanization is generally beneficial to increase farmers’ income, but in some areas it shows the opposite effect. Besides, as the positive effects of industrial urbanization on the changing of farmers’ incomes gradually expanding, their differences in different regions also expand over time. In terms of space, the areas with lower poverty reduction effect of industrial urbanization which are gradually shrinking from Hunan, Guangxi and other prefecture level cities to northeastern Guangxi, eastern and southern Hunan, and the areas with low population urbanization poverty reduction effect and high industrial urbanization poverty reduction effect are overlapped. 3) The impact of land urbanization on farmers’ income varies greatly in different regions. However, the mean value of the regression coefficient is always negatively shows that it plays a role of constraining the growth of farmers’ income, and there is a trend of enlarging gaps between different areas, the high-value areas are concentrate in Guangxi, northern and northeastern Sichuan, northeastern Chongqing, and southeastern Guangxi, with an overall distribution pattern of “high in the south and low in the north”. 4) The quality of urbanization has a significant positive impact on farmers’ income, with a trend of rising as a whole, this impact also has a characteristic of inverted “U-shaped”. In terms of space, Hunan Province has a stronger effect than other regions. Lastly, this article puts forward suggestions such as accelerating the process of population urbanization, rationally optimizing the structure of the secondary and tertiary industries, formulating a scientific land acquisition compensation system, and promoting high-quality urbanization development adapt to local conditions. |
