Abstract: Based on the endogenous regional financial development theory, a dynamic panel data model is developed in this article, in addition to which, the factor of poverty is included to emphasize the nonlinear relationship between regional finance and economy On a sample of objects down to the county level, system GMM is employed to test the different effects of finance on economy between poor and nonpoor counties The findings suggest that financial development in credit is positively associated with economic growth within both poor and nonpoor counties Financial development in savings is different within developing and developed regions, that is, savings is not correlated with economy in nonpoor counties, and it is negatively associated with economic growth in poor counties It is concluded that the theory of regional credit rationing and regional credit creation is more suitable to explain the financial development in poor regions, and the negative effect of savings is resulted from its outflow and low efficiency, which is related to the banking dominated by interregional institutions in China.
