摘　　要：本文在严成樑和龚六堂(2009)的基础上将消费性公共支出内生到家庭的效用函数中,在一个DGE框架下求解竞争性均衡问题,以此来考察生产性公共支出和税收对经济增长的影响。结论表明,生产性支出具有正的产出效应;生产性支出对家庭私人消费、公共消费的影响取决于政府设定的平滑税率。根据经验分析可知,生产性支出对经济的促进作用不如人口效应大,其中,基本建设支出并未对经济起到促进作用,可能已凸显出过度投资、重复建设等问题,这一现象在东西部地区更为明显;教育支出的增加促进了经济增长,并且在东中部地区较明显,而在西部地区仍未体现出来。On the basis of Yan and Gong （2009）, we introduce consumptive public expenditure into a household~ s utility function and solve the problem of competitive equilibrium, given exogenous productive public expenditure, in order to study the effects of both productive public expenditure and taxation on economic growth. It concludes that productive expenditure has positive effect and its effects of on both private and public consumption have a relationship with the optimal tax rate. Empirical analysis indicates that （1） the effect of productive expenditure on growth is less than that of population; （2） expenditure for infrastructure has the negative effect on productivity and this case is obvious in the areas of both East and West; （3） expenditure for public education increases productivity and it is evident in the areas of both East and Middle.
