摘　　要：借助2001-2016年279个地级及以上城市的面板数据集,运用面板双向固定效应模型,探究多中心空间结构对中国城市创新绩效的影响。其中市域空间结构的多中心程度通过识别陆地扫描全球人口数据库,综合考虑各中心的人口、距离和面积计算获得,城市创新绩效由城市年每万人专利申请量表征。研究结果表明,多中心空间结构对城市创新绩效有显著正向作用,且仅对经济发展水平高的城市成立。在样本时期内,科教投入、人口集聚、经济发展水平和公共服务水平的提升能够促进城市创新绩效,而投资驱动型城市建设对于城市创新绩效有一定的抑制作用。研究结论支持城市规划实践中多中心空间结构规划的合理性,并给出了相应的政策建议。This paper builds a panel dataset composed of 279 cities at or above the prefecture level from 2001 to 2016,and uses panel two-way fixed effects model to explore the impact of polycentric spatial structure on the innovation performance of Chinese cities.The polycentricity degree of urban spatial structure is obtained by identifying the LandScan dataset and comprehensively considering the population,distance,and area of each center,and the urban innovation performance is characterized by the number of patent applications per 10,000 people in the city.The research results show that the polycentric spatial structure has a significant positive impact on urban innovation performance,and it is only valid for economically well-developed cities.The results also indicate that,during the sample period,the increase of investment in science and education,population agglomeration,economic development,and improvement of public services can promote urban innovation performance,while the investment-driven urban construction has a certain restrictive effect on urban innovation performance.The paper provides support for the feasibility of polycentric spatial structure in urban planning practice,and also puts forward corresponding policy implications.
