摘要
目前,过大的城乡收入差距已成为中国经济发展的重要瓶颈,影响了社会的公正与稳定,故将城乡二元结构系数、外贸依存度以及城镇居民人均可支配收入发展速度作为城乡居民收入差距变动的影响变量,通过建立协整回归和误差修正模型得到反映它们之间长期均衡与短期波动的表达式。实证分析结果表明:城镇居民人均可支配收入发展速度是影响中国城乡居民收入差距变动的主要因素。
The income gap between urban and rural residents in China becomes much wider since reform and opening.The excessive rural-urban income gap becomes a major bottleneck in economic development,affecting social justice and stability.Therefore,it is necessary to analyze the factors that affect the rural-urban income gap,and to put forward some corresponding proposals to narrow this gap based on the results of the study.It＇s important for building a harmonious socialist society.This paper views dual structure coefficient,dependence on foreign trade,and growth rate of annual per capita disposable income of urban households as variables which affect the changes of rural-urban income gap.We get expressions reflecting the long-run equilibrium and short-term fluctuations between them through the establishment of cointegration regression and error correction model.The empirical results show that growth rate of annual per capita disposable income of urban households is a major factor affecting the changes of rural-urban income gap.
