中国城镇居民贫富差距扩大已经成为不可忽视的问题。通过分析中国城镇居民贫富差距的现状和成因,得出结论:应该发挥税收制度在促进再分配公平中的作用,通过改革税制来解决中国城镇居民贫富差距的问题。具体而言,应该通过改革个人所得税、建设遗产税等以健全中国的税收制度。 The widening gap between the rich and the poor in urban China has become a problem that can not be ignored. By analyzing the status quo and causes of the urban-rural gap between rich and poor in China, it is concluded that the tax system should play a role in promoting the redistribution of equity and reforming the tax system to solve the problem of urban-rural gap between rich and poor in China. Specifically, we should improve the tax system in China by reforming the personal income tax and building the estate tax.
