摘要
本文通过构建包含外资研发嵌入的城乡收入差距数理模型,从理论上探讨了外资研发嵌入对城乡收入差距的影响,进一步利用2000—2016年中国30个省份的面板数据,借助不变替代弹性生产函数和有向无环图方法实证研究了上述影响机制。研究显示:(1)从理论来看,外资研发嵌入的增加一般会缩小东道国城乡收入差距,但是如果东道国是大国,寡占反应理论导致的“战略效应”会拉大东道国城乡收入差距,该结论对于跨国公司利润汇回和东道国乡村劳动力自由流动具有稳健性;(2)从历史来看,2000年以来,中国城乡收入差距的构成发生了明显变化,类似“直接效应”的“创新效应”在占比上明显下降,而类似“战略效应”的“要素积累效应”在占比上明显上升,其中的劳动力报酬边际递减程度在占比上甚至略胜资本净积累程度;(3)从实证来看,与理论模型研究结论类似,外资研发嵌入有效地抑制了城乡收入差距,这一结论对于分区域的讨论、影响路径的分析具有稳健性。
This paper constructs a mathematical model of urban-rural income gap including foreign R&D embeddedness,and theoretically discusses the impact of foreign R&D embeddedness on urban-rural income gap,which is further tested using the panel data of 30 provinces,autonomous regions and municipalities(hereinafter referred to as provinces)in China from 2000 to 2016,together with the techniques of the constant elasticity substitution production function and directed acyclic graph used.The research shows that:(1)Theoretically,the increase of foreign R&D embeddedness will generally narrow the income gap between urban and rural areas in the host country,but if the host country is a big country,the“strategic effect”caused by oligopoly reaction theory will widen the income gap between urban and rural areas in the host country.This conclusion is robust for the profits repatriation of transnational corporations and the free flow of rural labor in the host country.(2)Historically,since 2000,the composition of China's urban-rural income gap has undergone significant changes.The proportion of“innovation effect”,similar to“direct effect”,has weakened significantly,while the proportion of“factor accumulation effect”,similar to“strategic effect”,has increased significantly,in which the decline of labor marginal remuneration is even slightly better than the net accumulation of capital.(3)Empirically,as is shown in the theoretical model conclusions,foreign R&D embeddedness has effectively restrained the income gap between urban and rural areas of the host country.This conclusion is robust for the discussion of sub-regions and the analysis of the impact path.
