交通基础设施促进中国区域经济长期增长的作用及机制分析

The Role and Mechanism of Transportation Infrastructure to Promote Long-term Growth of China’s Regional Economy

文章构建了交通基础设施促进中国区域经济增长的理论模型,并基于动态空间杜宾模型(DSDM),以全国285个地级市2006-2016年的有关数据,分析了交通基础设施促进中国区域经济增长的作用及机制。交通基础设施不仅直接促进中国的区域经济增长,还会通过空间外溢效应和反馈效应放大其促进作用。同时,交通基础设施对中国区域经济增长兼具有短期和长期的促进作用。因此,继续加大交通基础设施建设力度,统筹推进交通网络建设,将有利于更好地发挥交通基础设施对中国区域经济长期增长的促进作用。

This paper,based on the dynamic spatial Durbin model(DSDM)and the data of 285 municipal-level cities nationwide from 2006 to 2016,constructs a theoretical model of transportation infrastructure to promote regional economic growth in China and analyzes the function and mechanism of transportation infrastructure in accumulating China’s regional economic growth.The transportation infrastructure not only directly facilitates China’s regional economic growth,but also amplifies its facilitation through spatial spillover and feedback effects.At the same time,transportation infrastructure has both short-term and long-term acceleration on China’s regional economic growth.Therefore,continuing to strengthen the construction of transportation infrastructure and planning as whole to promote its networks construction will better exert the promotive function of transportation infrastructure to the long-term growth of China’s regional economy.
