农村基础设施及其空间溢出效应对农村经济增长的影响

现有经验研究的文献对农村基础设施与农村经济增长的关系具有2种相反的结论,其主要原因在于忽略了农村基础设施的存在空间溢出效应。利用1997-2008年我国省级农村经济增长数据和完全修正普通最小二乘法的面板协整估计,研究了农村基础设施及其空间溢出效应对农村经济增长的影响。结果显示：农村基础设施资本存量对我国农村经济增长具有显著的促进作用,而且农村基础设施资本存量也具有显著的空间溢出效应。这表明政府在加大对农村基础设施的投入力度的同时,还应协调相邻地区的农村基础设施投资,以充分发挥农村基础设施的最大经济效益,推动当地及相邻地区的农村经济增长。

Impact of Rural Infrastructure and its Spatial Spillover Effects on Rural Economic Growth

The opposite conclusion was drawn from the current empirical literatures on the relationship between rural infrastructure and rural economic growth,which is mainly contributing to the ignorance of spatial spillover effect in rural infrastructure.Based on panel cointegration and panel data of provincial rural economic growth from 1997 to 2008 in China,this paper analyzes the impact of rural infrastructure and its spatial spillover effect on rural economic growth.The result shows that capital stock of rural infrastructure has obviously promoted China＇s rural economic growth and it also has shown marked spatial spillover effect,which indicates that when increasinge investment in rural infrastructure,governments should coordinate the rural infrastructure investment in adjacent areas so as to take advantage of enormous effects of rural infrastructure and push forward rural economic growth in local and adjacent areas.
