| 摘要: |
| 将影响城乡收入差距的因素分解为对外开放程度、教育发展水平、金融发展水平、经济发展水平、市场化进程和城镇化进程，采用2005—2015年31个省市区面板数据进行夏普利值分解，结果表明经济发展、市场化和城镇化对城乡收入差距的贡献率较大，而对外开放、教育发展和金融发展对城乡收入差距的贡献率较小。线性回归分析表明扩大对外开放、深化市场化改革、加快经济和金融发展以及推进城镇化均有利于缩小城乡收入差距。进一步采用以经济发展水平为门槛变量的门槛效应模型的分析表明，经济发展对城乡收入差距的影响作用呈现倒U形曲线，而且经济发展水平越高，教育发展、金融发展、经济发展、市场化和城镇化等因素缩小城乡收入差距的作用越大。因此，要缩小城乡收入差距，必须加快欠发达地区的经济发展、对外开放、金融发展以及市场化和城镇化进程。 |

| Abstract: |
| The factors influencing urban-rural income gap are decomposed into opening-up degree, education development level, economic development level, marketization progress and urbanization process, the panel data of 31 provinces and municipalities during 2005-2015 are used to make the Shapley value decomposition, and the results show that economic development, marketization and urbanization have bigger contribution to urban-rural income gap, however, opening-up, education development and financial development have smaller contribution to the gap. The linear regression analysis indicates that the enlargement of opening-up, deepening the market-oriented reform, accelerating financial and economic development and boosting the urbanization are conducive to narrowing the income gap. The analysis of threshold effect model by further using the level of economic development as the threshold variable indicates that the effect of economic development on the urban-rural income gap shows an inverted U shape curve, furthermore, the higher the economic development level is, the bigger the effect of education development, financial development, economic development, marketization and urbanization and so on on the action narrowing the income gap is. Thus, in the process of narrowing the rural-urban income gap, China must accelerate the economic development, opening-up, financial development, marketization and urbanization for the less-developed areas. |
