Main purpose of this study is to find out the role of rural infrastructural development on economic growth of Pakistan. It has been hypothesized that rural infrastructural development has significant positive role for enhancement of economic growth. For the purpose of investigation we utilize such a model which may reflect the steady-state equilibrium differences in a Barro-type framework consisting of Solow type sets of variables and allow conditional convergence. On the basis of time series data set of Pakistan from 1981 to 2010, we employ OLS methodology so as to measure the impact of rural infrastructural development on economic growth of Pakistan. In view of limitations regarding categorization of data on regional basis, we use developmental public expenditures in rural areas as a proxy for rural infrastructural development. After analysis, we are of the view that rural infrastructural development has a positive role for economic growth of Pakistan, however, its role has found to be less significant in comparison to capital and labour as determinants of economic growth.
