摘　　要：研究目的:探究国家级城市群规划对城市空间结构的影响,为城市空间格局优化和区域一体化发展提供理论依据与政策建议。研究方法:赫芬达尔指数法,多期双重差分模型和标准差椭圆分析法。研究结果:(1)国家级城市群规划总体上显著推动城市空间结构多中心化发展;(2)经济集聚、产业集聚、扩大市场开放程度,促进要素市场高效配置以及改善政府间协作水平是国家级城市群规划促进城市空间结构优化的重要作用机制;(3)国家级城市群规划对偏单中心和偏多中心城市的空间结构均具有正向驱动作用,但对过渡型城市的空间结构作用效果不显著,且该规划对促进外围城市、“胡焕庸线”东南半壁、“博台线”西南半壁、第一梯队城市群以及第二批次规划实施地区的城市空间结构多中心化发展效果更显著。研究结论:应因地制宜完善城市空间结构动态规划方案,重点关注过渡型城市空间结构优化问题,分类引导中心城市发挥辐射带动作用,以系统推进城市空间结构优化。The purpose of this study is to investigate the impact of national-level urban agglomeration plan on urban spatial structure to provide theoretical basis and policy suggestions for optimizing urban spatial patterns and regional integration development.The research methods include the Herfindahl-Hirschman Index,multi-period differencein-differences model and standard deviation eclipse approach.The research results show that:1)the national-level urban agglomeration plan significantly promotes the polycentric development of urban spatial structure.2)Economic agglomeration,industrial agglomeration,expanding market opening degree,optimizing factors allocation and enhancing cooperation level among different governments are the critical influencing mechanisms of the national-level urban agglomeration plan to promote the optimization of urban spatial structure.3)In both cities with the monocentric and polycentric type of spatial structure,the national-level urban agglomeration plan could exert a positive driving effect,but the effect on the spatial structure of transitional cities is not significant.Moreover,this plan has a more significant effect on peripheral cities,cities of the southeast part of the Hu Huanyong Line,the southwest part of the Bole-Taipei Line,tier one urban agglomeration and the second batch of cities.In general,the dynamic adjustment mechanism of urban spatial structure should be established in accordance with local conditions,concentrate on the optimization of transitional urban spatial structure,categorically guiding central cities to exert their radiating and driving roles,and systematically promote the optimization of urban spatial structure.
