摘要
交通基础设施给国民经济发展提供了物质载体,对经济增长有着重要作用。本文基于全国31个省市2013—2019年的面板数据,通过构建固定效应模型,从交通基础设施的运营里程和密度来检验其对经济增长的作用。研究发现:公路、铁路运营里程和运营密度均对经济增长有显著的正向促进作用,其中公路交通基础设施对经济增长的正向作用更显著。
Transportation infrastructure acts as a material carrier for the development of the national economy and plays an important role in economic growth.Based on the panel data of 31 provinces and cities across the country from 2013 to 2019,this paper builds a fixed-effect model to test its role in economic growth from the operating mileage and density of transportation infrastructure.The study found that the operating mileage and operating density of roads and railways both have a significant positive effect on economic growth,and the positive effect of road transportation infrastructure on economic growth is more prominent.
