城市轨道交通与城乡融合协同发展对乡村振兴的影响——以郑州市为例

The impact of urban rail transit and synergistic development of urban-rural integration on rural revitalization:the case of Zhengzhou City

城乡融合发展是实现乡村振兴的重要途径,城市轨道交通与城乡融合协同发展可加快乡村振兴战略进程。本研究以郑州市为例,以最小加权平均旅行时间、经济潜力指标测评轨道交通可达性作为城市轨道交通发展水平,构建城乡融合发展及乡村振兴指标体系,采用熵值法、耦合协调度模型和VAR(向量自回归)模型探究城市轨道交通与城乡融合发展之间是否具备协同发展机制,进而分析协同发展是否影响乡村振兴。结果表明:2012—2020年耦合协调值由0.10上升至0.99,由极度失调发展为优质协调;格兰杰因果检验得出城市轨道交通与城乡融合协同发展对乡村振兴有单向因果关系。研究表明,城市轨道交通与城乡融合二者呈现协同发展趋势,协同发展对乡村振兴有促进作用。

Integrated urban-rural development is an important way to realize rural revitalization.This study explored the synergistic development of urban rail transportation and how urban-rural integration can accelerate the process of rural revitalization strategy.Taking Zhengzhou City as an example,this study used the minimum weighted average travel time and economic potential index to measure rail transit accessibility as the level of urban rail transit development,constructed an index system for urban-rural integration development and rural revitalization,and used the entropy value method,coupling coordination degree model,and vertor autoregressive model to investigate whether there is a synergistic development mechanism between urban rail transit and urban-rural integration development.In addition,whether synergistic development affects rural revitalization development was analyzed.The results showed that the coupling coordination value increased from 0.10 to 0.99 from 2012 to 2020,and developed from extreme disorder to high-quality coordination.The Granger causality test showed that there was a one-way causal relationship between urban rail transportation and the urban-rural integration synergistic development value and rural revitalization.The results of this study showed that both urban rail transportation and urban-rural integration have a synergistic development trend,and synergistic development has a catalytic effect on rural revitalization.
