中文摘要：

从质量视角出发，对城乡收入差距影响经济增长质量的作用机理进行理论阐释，并以1998--2012年中国30个省市区的面板数据为样本，采用差分GMM估计和系统GMM估计方法进行经验检验．结果显示：城乡收入差距过大，会影响经济增长的基础条件、运行过程以及最终结果，从而对经济增长质量产生制约作用。此外，人力资本投资、物质资本投资、政府支出规模、交通基础设施、非国有化程度以及经济开放的改善会对经济增长质量的提高产生积极影响，而金融发展和产业结构则对经济增长质量具有负面的影响。

英文摘要：

This paper explores the impact of urban-rural income disparity on quality of economic growth. By empirically analyzing Chinese provincial panel data from 1998 to 2012, the study finds that the estimation result of the model is well consistent with conclusions from theoretical study： urban-rural income disparity has significantly negative relationship with the quality of economic growth. Furthermore, the in- vestment in human capital, the investment in material capital, the government expenditure, the transporta- tion infrastructure, the non nationalization and the open economy have significantly positive relationships with the quality of economic growth, while the financial development and industrial structure are negatively correlated with quality of economic growth.
