摘要
城市集群是随着城市间交通时间不断缩短、市场一体化程度不断提高而出现的空间现象.本文以2008-2020年243个外围城市为研究对象,使用全球卫星夜间灯光和交通时间的匹配数据集,构建城市集群和城市空间演化的量化指标,实证分析外围城市集群对其空间演化的影响及作用机制.研究发现外围城市集群显著加速了其内部空间集中化.进一步,本文使用清代城市历史地理数据构建工具变量讨论模型内生性,并开展系列稳健性和异质性分析,证实了结论的稳健性.机制分析表明,在双"核心-外围"关系并存的空间中,外围城市集群增强了其核心区劳动力和企业的集聚效应,且该效应会随着核心区主导能力的增强而增强.本文将城市空间演化方面的研究视角拓展至双"核心-外围"空间尺度,研究结论可为理解我国城市空间演化、促进区域协调发展提供新的思路和参考.
Abstract
City cluster is a spatial phenomenon that appears with the continuous shortening of commuting time between cities and the continuous improvement of market integration.Taking 243 peripheral cities from 2008 to 2020 as the research object,this paper uses the matching data set of global satellite night-time light data and commuting time to build quantitative indicators of city clusters and city spatial evolution,and empirically analyzes the impact of peripheral city clusters on their spatial evolution and their operational mechanism.The research finds that the city cluster has significantly accelerated its internal spatial concentration.Then the paper discusses the endogeneity using the instrumental variables constructed from the historical geographic data of cities in the Qing Dynasty,and carries out a series of robustness and heterogeneity analysis.Further mechanism analysis confirms that in the dual"core-periphery"space,the peripheral city clusters can enhance the agglomeration effect of labor and enterprises in core areas,and this effect will be enhanced with the increase of the dominance of the core areas.The paper expands the research on city spatial evolution to the scale of dual"core-periphery"space.The conclusions may provide new ideas for a deep understanding of city spatial evolution and solidly promoting common prosperity in China.
