城乡收入差距问题是我国二元经济所必须面对的问题,经济的发展与收入差距的扩大存在一定的关系。本文以武汉市经济增长(人均GDP增长)和城乡收入差距的数据,通过设定一元线性回归方程,序列相关性的修正,模拟估计经济增长与收入差距扩大的线性关系,发现经济增长速度每增加1%,城乡收入差距扩大速度增长0.935%,存在正向稳定的关系。对城乡收入差距的调整以及对于“刘易斯拐点”的应对,需要政府作出努力以及加强新农村劳动力的建设和发展。
The problem of income gap between urban and rural areas is a problem our country’s dual economy must face. There is a certain relationship between economic development and the expansion of income gap. This paper, based on the data of economic growth (per capita GDP growth) and income gap between urban and rural areas in Wuhan, sets up a linear regression equation and the correction of sequence correlation to simulate the linear relationship between economic growth and income gap expansion. It is found that for each increase of economic growth rate 1%, the income gap between urban and rural areas has expanded by 0.935%, showing a positive and stable relationship. The adjustment of the income gap between urban and rural areas and the response to the “Lewis turning point” require the government’s efforts and the construction and development of the new rural labor force.
