基于内生经济增长理论的核心观点,本文在专用要素模型分析框架下将国际外包的经济效应分解为产出技术效应和成本技术效应,对外包与中国城乡收入差距的关系进行了实证研究。结果显示,在当前城乡人力资本水平存在明显差异的情况下,收入差距与中间品贸易存在着长期稳定的均衡关系,而中间品贸易进口和贸易结构的升级则是导致差距扩大的重要原因。因此,缩小城乡人力资本水平的差异应该成为解决城乡收入差距问题的长期着力点。 Based on the core view of endogenous economic growth theory, this dissertation decomposes the economic effect of international outsourcing into output technology effect and cost-technology effect under the framework of special factors model analysis, and makes an empirical study on the relationship between outsourcing and the income gap between urban and rural areas in China. The results show that there is a long-term and stable equilibrium relationship between income gap and the trade in intermediate goods under the current significant differences in urban and rural human capital levels, while the import of trade in intermediate goods and the upgrading of the trade structure are the important reasons leading to the widening of the gap. Therefore, narrowing the gap between urban and rural human capital should become the long-term focal point for solving the problem of urban-rural income disparity.
