随着区域合作的深入，区域市场一体化成为未来的发展趋势，但区域市场一体化如何影响收入不平等仍不甚清晰。以长江中游三省为例，采用面板固定效应方法和面板分位数回归方法，实证检验了区域市场一体化、劳动力流动对收入不平等的影响。面板固定效应估计结果表明区域市场一体化、劳动力流动都有助于减小收入差距，并且区域市场一体化通过促进永久性的劳动力流入减小了收入差距；而暂时性的劳动力流入并没有明显改善收入不平等。面板分位数模型可以反映各条件分位点处变量间的关系，结果表明区域市场一体化、劳动力流动减小收入不平等的作用在收入不平等更加严重的地区表现更加明显。稳健性检验表明面板模型分析结果是可信的和稳健的，区域市场一体化通过促进永久性劳动力流入，减小了收入不平等。因此，通过深入推进区域市场一体化进程，消除行政和体制机制壁垒，改革户籍制度等制度性障碍，促进劳动力的永久性流动，将有助于减小收入不平等程度。另一方面，在不同地区应该采取差异化政策，通过积极参与市场一体化建设和消除阻碍劳动力流动的制度性障碍，改善收入不平等状况。

With the deepening of regional cooperation ,the regional market integration becomes a trend in the future ,but how the regional market integration affects the income inequality is still not very clear. Taking the three provinces in the middle reach of Yangtze River as an example ,we use fixed effect panel method and panel quantile regression method to investigate the effects of regional market integration ,labor mobility on income inequality. Fixed effect panel estimation results show that the regional market integration ,labor mobility is helpful to reduce the income gap. By promoting permanent labor inflow , regional market integration reduces income gap , while temporary labor inflow does not significantly improve income inequality. Panel quantile regression model can reflect the relationship between variables ,and the results show that regional market integration ,labor mobility may reduce income inequality where income inequality is more obvious. Robustness test shows that previous results are reliable and steady. So ,deepening regional market integration , eliminating the administrative and institutional barriers , reforming the household registration system ,et al ,to promote permanent inflow of the labor force ,it will help to reduce income inequality. On the other hand ,the government should take differentiation policies in different areas ,actively participate in market integration and eliminating of the institutional barriers which hinder the labor mobility to ameliorate income inequality.
