abstract governments in regional and national level try to improve economic and productivity growth by different polices. the being aware of effective factors in national and regional economic and productivity growth is essential for government success. in this paper, to being of aware determinant factors in productivity inequality, we use decomposition approach and econometric estimation for 20 provinces in 2001-2006 (1380-1385). the results in panel data and fixed effects framework show that the public government expenditure and structure of production has had determinant role in improving of total productivity, while, the human capital and investment government expenditure that improve production, has had improving role. also, the results verify that total productivity in iranian regions/provinces had been exogenous and endogenous variables had been had small share in total productivity in iranian regions/provinces, and the role of economic structure in provinces ranking is thinkable.
