摘要 基于2009—2020年中国282个地级以上城市的面板数据,分析了通达性的改善对我国城市空间效率影响及作用机制。研究发现:(1)通达性的改善能够促进城市空间效率提升,且可以有效吸引劳动力与资本的集聚,促进城市土地要素的有效利用;(2)城市通达性对城市空间效率的直接促进作用大于通过要素集聚作用于城市空间效率的间接促进作用;(3)分城市规模和经济禀赋来看,城市通达性的变化对大规模城市和贫困地区城市的城市空间效率影响程度分别大于对中小规模城市和非贫困地区城市的影响程度。因此,加快交通基础设施建设,促进城市间互联互通,激发要素集聚的中介效应,将有助于中国城市高效率发展。

Abstract: Based on the panel data of 282 cities above prefecture level in China from 2009 to 2020, this paper analyzes the influence and mechanism of accessibility improvement on urban spatial efficiency in China. The results are as follows: (1) The improvement of accessibility can promote the efficiency of urban space, effectively attract the agglomeration of labor and capital and promote the effective use of urban land elements; (2) The direct promoting effect of urban accessibility on urban spatial efficiency is greater than the indirect promoting effect of factor agglomeration on urban spatial efficiency; (3) From the perspective of city size and economic endowment, the impact of changes in urban accessibility on the urban spatial efficiency of large-scale cities and cities in poverty-stricken areas is relatively greater than that of small and medium-sized cities and cities in non-poor areas. Therefore, speeding up the construction of transport infrastructure, promoting the interconnection between cities and stimulating the intermediary effect of factor agglomeration will contribute to the efficient development of Chinese cities.
