经济发展与农村减贫耦合机理及协调性研究以重庆市为例

目的 为探究重庆市经济发展水平与农村减贫耦合协调的时空格局。方法 文章在分析经济发展与农村减贫耦合机理的基础上,使用洛伦兹曲线和耦合协调模型,定量测算33个涉及扶贫开发任务区县经济发展与农村减贫的耦合协调度。结果 （1）经济发展对于农村减贫具有正向带动作用,但随着脱贫攻坚的深入,经济发展带动农村减贫的作用逐渐减弱;（2）重庆市县域经济发展水平整体呈现“一圈两翼”的特征,中心城区及周围区县为经济发展高值区,渝东南武陵山区和渝东北秦巴山区为经济发展低值区,贫困空间分布格局与之相反;（3）重庆市县域经济发展与农村减贫的耦合协调度呈现显著的空间不均衡格局,在主城都市区形成了明显的高值区,渝东北和渝东南连片特困地区形成明显的低值区;从时间序列来看,耦合协调状态整体呈现逐级正向跃迁的趋势。结论 基于经济发展与农村减贫耦合协调状态的空间差异性,未来应因地制宜、分区分类精准施策,稳步推进脱贫攻坚与乡村振兴的衔接。

COUPLING MECHANISM AND COORDINATION OF ECONOMIC DEVELOPMENT AND RURAL POVERTY ALLEVIATIONA CASE STUDY IN CHONGQING

In order to explore the spatial-temporal pattern of coupling and coordination between Chongqing''s economic development and rural poverty alleviation. Based on the analysis of the coupling mechanism of economic development and rural poverty alleviation, this paper used the Lorenz curve and the coupling coordination model to quantitatively calculate the coupling coordination degree of economic development and rural poverty alleviation in 33 counties with poverty alleviation and development tasks. The research results showed that: (1) During the research period, the economic development had played a positive role on rural poverty alleviation. But with the deepening of poverty alleviation, the role of economic development in rural poverty alleviation had gradually weakened. (2) The overall economic development level of Chongqing''s counties showed the direction of "one circle, two wings". The central urban area and the surrounding districts and counties were high-value areas for economic development, the southern Wuling mountainous area in eastern Chongqing and the Qinba mountainous area in northeast Chongqing were low-value areas for economic development, and the spatial pattern of poverty showed an opposite direction. (3) The coupling and coordination degree between economic development of the counties and rural poverty alleviation in Chongqing showed a significant spatial imbalance pattern. The central city metropolitan area formed an obvious high-value area, and the poverty areas in the northeastern and southeastern Chongqing formed an obvious low-value area. From the perspective of time series, the coupling and coordination state showed a trend of positive transition step by step as a whole. In conclude, according to the spatial difference of the coupled and coordinated state of economic development and rural poverty alleviation in the future, we should adapt to local conditions and accurately implement classified governing strategies to steadily promote the connection between poverty alleviation and rural revitalization.
