摘要
城市群已经成为我国新型城镇化深入推进的主要空间支撑形态,厘清哪种空间结构更有利于提高城市群的经济绩效,有助于为“十四五”乃至更长时期的城市群空间规划提供决策依据.本文基于陆地扫描全球人口数据库和欧洲航天局全球土地利用数据识别城市实体,并从单中心-多中心视角测度城市群空间结构,运用固定效应模型和工具变量法检验城市群空间结构对劳均GDP和劳均GDP增长率的影响.结果显示,多中心的空间结构更有助于促进城市群经济绩效的提高.未来空间规划应在发挥首位城市辐射带动作用的基础上,促进经济要素在城市群中整体均衡分布,形成各城市协调发展、合理有序的空间结构体系.
City clusters have become the main spatial support for further promotion of China's new urbanization. Clarifying which spatial structure is more conducive to improve the economic performance is helpful for providing decisio making basis for spatial planning of city clusters, particularly during the 14th Five-Year Plan period. Based on the global population database of Landscan and the global land use data from ESA, this paper identifies urban entities and measures the spatial structure of city clusters from a monocentricpolycentric perspective. The fixed-effect model and instrumental variable method are used to test the effect of spatial structure on GDP per labor force and growth rate of GDP per labor force. The results show that polycentric spatial structure is associated with better economic performance of city clusters. Based on enhancing the radiation and driving role of the primate city, the spatial planning of city clusters should promote the overall balanced distribution of economic factors, aiming at a coordinated, rational, and orderly spatial structure system.
