在长期以经济发展为纲的政策导向下,我国城镇居民和农村居民的收入差距明显扩大,已成为一个严峻的社会问题。本文对全国31个省市区的城乡收入结构进行实证分析,研究造成收入二元化的有效影响因素,提出应充分利用分项收入有差别的不平等效应来缩小城乡收入不平等,实现收入结构优化。 Under the policy of long-term economic development, the income gap between urban residents and rural residents in our country has obviously expanded and has become a serious social problem. This paper empirically analyzes the income structure of urban and rural areas in 31 provinces in China and studies the effective factors that cause the income to be dualized. It proposes that the inequality of income inequality between urban and rural areas should be reduced to make full use of the income inequality and income structure optimization.
