Heterogeneity and Evolution Characteristics of Poverty Reduction Effect of Prefecture-level Cities' Urbanization in Hunan,Chongqing,Sichuan,Yunnan,Guizhou and Guangxi

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.
