中国新型城镇化、乡村振兴与生态文明建设耦合协调发展研究

Study on the coupled and coordinated development of new urbanization,rural revitalization and ecological civilization construction in China

基于2001—2020年中国30个省级面板数据,构建指标体系,运用耦合协调度模型和空间自相关模型,定量分析中国新型城镇化—乡村振兴—生态文明建设耦合协调度及其时空演变特征。结果表明:①中国新型城镇化、乡村振兴、生态文明建设指数均呈上升趋势,且在空间上分布不均衡,具有“东高西低”的特征。②中国新型城镇化—乡村振兴—生态文明建设耦合协调水平呈现“中级协调—良好协调”的演进态势,各省区分布不平衡,耦合协调类型呈现“濒临失调—初级协调—中级协调”的演变趋势。③耦合协调度在空间上表现出正的空间自相关,空间集聚性总体呈现下降趋势。东部沿海地区表现为“高—高”类型集聚,西部地区表现为“低—低”类型集聚,“高—高”类型和“低—低”类型的分布范围均表现出明显的收缩态势。

Based on the panel data of 30 provinces in China from 2001 to 2020,this paper constructed an evaluation index system,and used the coupling coordination degree model and spatial autocorrelation model to quantitatively analyze the coupling coordination degree and spatio-temporal evolution characteristics of China′s new urbanization-rural revitalization-ecological civilization construction.The results showed that:①China′s new urbanization,rural revitalization,and ecological civilization construction index all showed an upward trend,and the spatial distribution was uneven,with the characteristics of“high in the east and low in the west”.②The coupling coordination level of China′s new urbanization-rural revitalization-ecological civilization construction presented an evolution trend of“intermediate coordination-good coordination”,with unbalanced distribution among provinces and regions,and the coupling coordination type presented an evolution trend of“near imbalance-primary coordination-intermediate coordination”.③The degree of coupling coordination showed a positive spatial autocorrelation in space,and the overall spatial agglomeration showed a downward trend.The eastern coastal area was characterized by“high-high”type agglomeration,while the western area was characterized by“low-low”type agglomeration.The distribution range of“high-high”type and“low-low”type both showed a significant contraction trend.
