摘要
改革开放初期随着经济的增长,居民收入差距在缩小;但近年来我国经济快速发展,收入差距反而持续拉大。本文首先对中部六省的城乡收入差距进行测算,发现经济增长与收入差距一阶差分后均平稳,且存在协整关系。因此本文利用门限回归模型,基于中部六省1981年到2012年的面板数据,根据我国的经济政策对经济增长和收入差距进行实证分析。根据门限值和门限自抽样效果检验确定门限回归的类型,由门限回归的参数估计值确定最终的门限回归模型。最终根据不同制度变量下的门限回归模型,判断收入差距对经济增长的门限效应。
At the beginning of China’s reform and opening-up,with economy growing,the income gap is narrowing.But recently,in sharp contrast with rapid economy development,the income gap is widening. After measuring the income gap between urban and rural areas in six central provinces,this paper finds that economic growth and income inequality were stable after the first difference,and there exists co-integration. This paper on the basis of six central provinces’ panel data from 1981 to 2011,uses threshold panel data regression model to analyze the relation between economic growth and the income gap. According to LR statistics this paper determines the threshold number,then uses the threshold panel to judge the income gap’s threshold effect on economic growth from the perspective of policy.
