在一个两部门内生增长模型中,讨论政府财政政策变化对居民消费,资本积累以及经济增长的长期影响和短期影响.发现在短期内,政府增加资本收入税不仅可以增加居民消费,而且可以刺激人力资本积累,从而刺激短期经济增长.但是政府财政政策改变对长期经济增长不产生影响,而且资本收入税会降低长期的消费水平和资本存量.另外,从经济增长形态和消费者福利两个角度讨论了资本收入税的无效性.
In a two-part model of endogenous growth, we discuss the long-term and short-term effects of changes in government fiscal policy on household consumption, capital accumulation and economic growth, and find that in the short term, increasing the capital income tax by the government will not only increase residents’ consumption but also stimulate Human capital accumulation, thereby stimulating short-term economic growth.But the change of government fiscal policy does not have an impact on long-term economic growth, and capital income tax will reduce long-term consumption level and capital stock.In addition, from the perspective of economic growth and consumer welfare Discusses the ineffectiveness of the capital income tax.
