混合经济的最优增长分析

在混合经济中,政府可以通过公共资本的增加来提高私人资本的边际生产力,促使经济在最优状态下实现持续增长。而社会性的最优增长状态,可以通过设定适当的税收和国债政策,在混合经济中得以实现。为达到最优增长状态,在短期内,可以通过递减的消费税率来抵消对资本收益征税的负面影响,但长期而言,必须避免对资本收益进行征税。同时,虽然国债是中立的,但国债为最优税收政策提供了更多样化的选择。

Dynamic Analysis of a Growth Model of the Mixed Economy

In mixed economy, the government can raise the marginal productivity by increasing public capital, so as to promote a continuous economic development under its optimum condition. The social optimum condition for mixed economy can be realized through setting up appropriate policies on tax and national debt. In a short period,for this purpose, degressive excise rate can counteract the negative effect of capital gain tax. While in a long-term plan, capital gain tax should be exempted. National debt is neutral, but it provides alternatives for the optimum tax policies.
