Purpose -The purpose of this paper is to construct a financial development index (FDI) for the Indian economy and also examine the relationship between FDI and economic growth. Design/methodology/approach -Augment Dickey Fuller, Phillips Perron and Ng Perron unit root tests are employed in order to determine the level of integration. The long-and short-run dynamics are obtained by using auto-regressive distributed lag approach to cointegration and rolling window approach to estimate coefficient of each observation. Findings -The results indicate that long-run relationship is presented among the economic growth, FDI, real-interest rate (RIR), labor force and capital. But FDI negatively associated with economic growth in the case of long-and short-run and RIR also negatively determine the economic growth only in the long run. The rolling regression result confirms that FDI negatively associated to growth in the
