In an economy system, government activities play a fundamental role in economic growth and development of countries, but increase these activities have a positive effect on economic growth until a certain threshold and from this threshold excessive increase in government activities not only have no positive effect on economic growth, but these activities are main barrier to growth. Including of these activities, can mention the government''s capital expenditures and public debt. In this study, is tried to study the threshold effects and non-linear government investment and public debt on GDP in two separate models during of 2000-2016 using of provincial data and Panel Smooth Transition Regression Model (PSTR). The results of linearity test show that there is a nonlinear relationship between variables. Also, the inclusion of a transfer function with a threshold parameter which is representing a two-regime model, is sufficient to determine the nonlinear relationship between variables. The results show that public debt and investment in first regime have a positive effect on GDP, but by crossing of threshold and entering to second regime, severity of this effect will be increased and negative. It seems, this result is due to the crowed-out effect on private sector and increase in public debt due to rising government spending and confirms Laffer curve hypothesis.

Government size has negative and positive impact on economic growth. In this paper, we conduct an analysis with dealing the impact of government size on human development index (HDI). The regression will be empirically analyzed using generalized method of moments (GMM) with two staged least squares in a panel data framework for 30 developed and 34 developing nations for 1980-2009. The impact of government size (measured by consumption and investment expenditures) on HDI is studied. The results reveal that the optimal size of government consumption expenditure on HDI in developed countries is greater than the developing countries. While, in developing countries the government investment reveals a linear and increasing patterns.
