Abstract: This paper establishes an endogenous growth model with two different types of government fiscal expenditure, and analyzes the optimal fiscal consumption expenditure with economic growth maximization. Our theoretical findings are as follows: the proper fiscal consumption expenditure can optimize allocation of resources, promote economic growth and realize positive externalities of public consumption goods; the excessive or insufficient fiscal consumption expenditure will give the negative effect on economic growth. Meanwhile, the paper through numerical analysis demonstrates that the fiscal consumption expenditure’s impact on the economic growth can be described in an inverted “U” form. By empirically analyzing the influence of the fiscal consumption expenditure on the economic growth, we find that the relationship between these two variables is strongly positive in the period of 2000-2006, but the positive influent becomes weaker in the period of 2009-2012 with the actual fiscal consumption expenditure getting close to the optimal expenditure, especially in the western region. The consumption structure of the economic development level influences the optimal fiscal consumption expenditure. The government should assess the economic situation and adjust the scale of fiscal consumption expenditure accordingly so as to achieve steady economic growth.
