摘　　要：提高城市交通设施与公共服务的供给效率,以增强对人口和经济活动集聚的支撑能力,对城市的可持续增长至关重要。本文在新经济地理学的框架下构建理论模型,识别城市交通设施供给效率与城市规模协同影响城市生产率的理论机制,并利用2004—2016年地级市及以上城市面板数据进行实证检验。研究发现,城市规模扩大获得的边际收益随交通设施与公共服务总体供给效率的提高而提高。在平均规模的城市中,供给效率每提高0.1,城市劳动生产率将提高0.13%。考虑模型可能存在的内生性和进行稳健性检验后,模型的估计结果依然成立。分区域的估计结果表明,提高供给效率所释放的城市集聚经济效益在东部地区高于中西部地区。相较于中小城市,大城市更能从供给效率提高中获益。Improving the provision efficiency of transport facilities and public services to strengthen the support for the agglomeration of population and economic activities is crucial for the sustainable growth of cities.This paper constructs a theoretical model based on the New Economic Geography framework to explore the synergistic mechanism of provision efficiency of transport infrastructure and city size affecting urban productivity.We employ prefecture and higher city level panel data from 2004 to 2016 to do the empirical analysis.The results indicate that the marginal productivity gained as city grows in size will increase with the improvement of the provision efficiency of transport infrastructure and public services.For average-sized cities,every 0.1%increase in the provision efficiency will lead to a 0.13%increase in urban labor productivity.The estimation results remain tenable after endogeneity is taken into consideration and robustness test is conducted.The empirical estimation results of the sub-region suggest that,the agglomeration benefit released by provision efficiency improvement is larger in eastern regions than in central and western regions.Large cities can benefit more from the improvement of provision efficiency.
