本文建立了一个考虑生产性公共支出和环境污染作用的内生经济增长模型，分析了稳态增长均衡下最优财政政策的性质。我们认为消费水平是污染的来源。政府将其税收在减少污染支出和生产性公共支出之间进行分配。当生产性公共支出被描述为税收收入减去减排支出时，生产性公共支出与国民收入的最优比例等于公共投入的竞争性产出份额。然而，比例所得税率超过了公共投入的竞争性产出份额。在稳态增长均衡中，社会福利最大化解与增长率最大化解之间不存在冲突。当经济增长率高于某一临界水平时，唯一的稳态增长均衡似乎是一个鞍点，而市场经济中的稳态均衡增长率不一定低于社会有效增长率。(C)2009 Elsevier B.V.保留所有权利。
This paper develops a model of endogenous economic growth with special consideration to the role of productive public expenditure and environmental pollution; and analyses the properties of optimal fiscal policy in the steady state growth equilibrium. We consider the level of consumption as the source of pollution. Government allocates its tax revenue between pollution abatement expenditure and productive public expenditure. Optimum ratio of productive public expenditure to national income is equal to the competitive output share of the public input, when productive public expenditure is depicted as tax revenue minus abatement expenditure. However, the proportional income tax rate exceeds the competitive output share of the public input. There is no conflict between the social welfare maximizing solution and the growth rate maximizing solution in the steady state growth equilibrium. The unique steady state growth equilibrium appears to be a saddle-point when the growth rate is above a critical level and the steady state equilibrium growth rate in the market economy is not necessarily lower than the socially efficient growth rate.
