基础设施投资的空间溢出效应分析——以沪昆线沿线城市为例

以沪昆铁路沿线区域及城市经济发展为分析对象,实证分析了我国基础设施投资的空间溢出效应。认为沪昆线的基础设施投资既产生了提高沿线区域及城市的运输能力、扩大沿线贸易量、调整沿线产业结构、促进沿线经济增长的空间正溢出效应,也产生了加剧沿线地区及城市要素的非均衡流动、非均衡经济增长的空间负溢出效应。

Analysis to the spatial spillovers effects of infrastructure investment:taking the cities for example along the Shanghai-Kunming Railway Line

Taking Shanghai-Kunming Railway for example,this article makes an empirical study on the spatial spillover effect of China’s space infrastructure investment in order to know a positive role in regional and urban economy through infrastructure investment.The study has found that the infrastructure investments of Shanghai-Kunming Line has been playing a positive spatial spillover effects of increasing regional and urban transport capacity,expanding trade size,adjusting industrial structure,and promoting economic growth along the line,but it has also generated a negative spatial spillover effects of increasing the non-equilibrium flow of regional and urban elements,and non-balanced economic growth along the route.
