公共交通设施规模对绿色经济效率的影响

公共交通与人们的生产和生活息息相关，是城市经济发展的“动脉”。基于“公交优先”背景，利用2004~2016年中国265个地级及以上城市的面板数据，实证考察公共交通设施规模对绿色经济效率的影响作用。结果表明：公共交通设施规模与绿色经济效率之间存在显著的“U型”曲线关系；相对西部地区，两者之间的“U型”曲线关系在东部和中部地区表现更为明显；相对中等城市，两者之间的“U型”曲线关系在大城市表现更为明显，而在小城市呈“倒U型”曲线关系，且不显著。本研究为交通基础设施影响城市经济发展提供了新的证据和视角。

Impact of Public Transport Facility Scale on Efficiency of Green Economy

Public transport is closely related to production and people’s life, and is the “artery” of urban economic development. Based on the background of “public transit priority”, this paper empirically investigates the impact of the scale of public transport facilities on the efficiency of green economy by using the panel data of 265 cities at prefecture level and above in China from 2004 to 2016. The results show that there is a significant “U-shaped” curve relationship between the public transport facility scale and the efficiency of green economy. Compared with the western region, the “U-shaped” curve relationship is more obvious in the eastern and central regions. Compared with medium-sized cities, the “U-shaped” curve relationship is more obvious in large cities while the “inverted U-shaped” curve relationship is insignificant in small cities. This paper provides new evidence and perspective for the impact of transportation infrastructure on urban economic development.
