中文摘要：

本文运用我国1985—2012年的农民工、农民、制造业和农林牧副渔的收入数据，建立数理模型分析收入差距、农村人力资本深化以及城乡融合间的相互关系。比较分析得出，农村人力资本深化使得农民工、农民、制造业和农林牧副渔的收入差距存在逐渐缩小的收敛性特征，收入差距的收敛性促进了城乡融合。农村人力资本深化的主要原因是我国教育水平的提高和农村社会发生变化。因此，继续扩大义务教育年限和贯彻落实新型城镇化将会进一步提高农村人力资本深化，加快城乡融合。

英文摘要：

This article uses the data of the income of peasant workers, peasants, manufacturing industry, and agriculture, forestry, animal husbandry and fishery over the 1985 -2012 period, and sets up mathematical model to analyze the relationship among income gap, the deepening of rural human capital and the integration of city and the countryside. According to the analysis, we can draw the conclusion that the deepening of rural human capital makes such income gap show some convergence characteristics with gradual decrease which promotes urban - rural integration. The main cause for the deepening of rural human capital lies in the improvement of education level in our country and the changes in rural society. As a result, to continuously extend the years of compulsory education and realize new urbanization will not only further promote the deepening of rural human capital but also speed up urban- rural integration.
