三峡库区重庆段新型城镇化的乡村减贫效应及影响因素分析

Analysis of Rural Poverty Reduction Effect of New Urbanization and Influencing Factors in the Three Gorges Reservoir Area of Chongqing

据三峡库区重庆段15个区县2013-2018年的面板数据,利用熵值法和改进的C-D生产函数模型测度新型城镇化的乡村减贫效应,并利用地理探测器探究其影响因素。结果表明:(1)15个区县的新型城镇化水平总体呈上升趋势,综合得分均值由2013年的0.2931上升到2018年的0.4665;(2)新型城镇化发展具有多维减贫效应,对乡村经济、人民生活、教育医疗的减贫效应系数值分别为-0.237、-0.517、-0.621,后两个维度减贫效应更好;(3)各维度减贫效应在空间上存在显著差异,新型城镇化对乡村经济和教育医疗减贫较好的地区集中在库区中部和东北部的区县,人民生活减贫效应较好的地区集中在主城区及其周边区县;(4)人口城镇化率和与主城区的距离是三峡库区重庆段新型城镇化乡村多维减贫效应的主要影响因素。研究结果可以为三峡库区重庆段巩固脱贫成效及乡村振兴提供参考借鉴。

According to the panel data of 15 districts and counties in the Three Gorges Reservoir Area of Chongqing from 2013 to 2018,the entropy method and improved Cobb-Douglas production function model were used to measure the rural poverty reduction effect of new urbanization,and Geodetector was used to explore its influencing factors.The results show that:the overall level of new urbanization in 15 districts and counties increased,and the average comprehensive score increased from 0.2931 in 2013 to 0.4665 in 2018;the development of new urbanization has multi-dimensional poverty reduction effect on rural areas,and the poverty reduction effect coefficients of rural economy,people's life,education and health care are-0.237,-0.517,-0.621 respectively,the latter two dimensions having better poverty reduction effect;there are significant spatial differences in poverty reduction effects in various dimen sions,and the areas where new urbanization has better poverty reduction in rural economy,education and medical treatment are concentrated in the central and northeastern regions of the reservoir area,while the areas with better poverty reduction effects on people's lives concentrated in the main urban area and surrounding districts and counties;the urbanization rate of population and the distance from the main urban area are the main influencing factors of the multidimensional poverty reduction effect of the new urbanized villages in the Three Gorges Reservoir Area of Chongqing.The research results can provide references for the consolidation of poverty alleviation effective ness and rural revitalization in the Three Gorges Reservoir Area of Chongqing.
