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.
