乡村振兴背景下乡村建设与资源环境耦合协调的动态演进分析

Analysis on the Dynamic Evolution of the Coupling and Coordination between Rural Construction and Resource Environment under the Background of Rural Revitalization

乡村建设与资源环境的协调发展是乡村振兴的物质保证与生态基础。论文以2006—2020年为研究期,构建乡村建设—资源环境系统评价指标体系,通过熵权法、耦合协调度模型计算28个省份的乡村建设与资源环境耦合协调度,运用Dagum基尼系数探究协调度的区域差异及动态演进,并利用空间收敛模型研究这种差异是否存在收敛。研究发现:(1)考察期内中国乡村建设与资源环境耦合协调水平呈现平稳上升的趋势,但总体水平较低且处于基本协调状态。地区异质性特征明显,其耦合协调度呈现出由东至西阶梯递减的规律。(2)中国乡村建设与资源环境耦合协调水平的总体差异在波动降低,区域间差距是总体差异的主要来源。(3)耦合协调水平在全国及东部、中部、西部地区均存在显著的空间收敛过程,收敛速度从高到低依次为中部地区、东部地区、西部地区。该研究对把握中国乡村建设与资源环境发展规律,全面推进乡村振兴都具有积极的现实意义。

The coordinated development of village and town construction and resource environment is the material guarantee and ecological basis of Rural Revitalization.Taking 2006-2020 as the research period,this paper constructs the evaluation index system of the village construction and resource environment system.It calculates the coupling coordination of village construction and resource environment in 28 provinces and cities through the entropy weight method and the coupling coordination degree model.The Dagum Gini coefficient is employed to explore the regional differences and dynamic evolution of the coordination degree,and the spatial convergence model is used to study whether there is convergence of this difference.The study found that:(1)during the investigation period,the coupling and coordination level of China’s village and town construction and resources and environment showed a steady upward trend,but the overall level was low and basically coordinated.From east to west,the regulation shows obvious characteristics of stepwise coupling.(2)The overall difference in the coupling and coordination level between rural construction and resources and environment in China is fluctuating and decreasing,and the regional gap is the main source of the overall difference.(3)The coupling coordination level has a significant spatial convergence process in the whole country and the east,middle and west regions.The convergence speed from high to low is the central region,the east region and the west region.This study has positive practical significance for grasping the law of China’s rural construction and resource environmental development,and comprehensively promoting rural revitalization.
