社会资本与中国农民工收入差距

Social Capital and Income Gap of China's Peasant Workers

文章在探讨社会资本对中国农民工收入差距的影响机制基础上,将农民工新型社会资本划分为情感性和工具性两种类型,并运用夏普利值分解方法对不同类型社会资本和农民工收入差距的关系进行实证分析。结果发现,新型社会资本中的工具性社会资本对农民工的收入和收入差距都有一定的影响,而造成这种影响的主要原因是工具性社会资本的分布不均。在市场化程度和经济发展水平较高的东部地区,作为非正式制度的社会资本对农民工收入差距的影响明显小于相对落后的中部地区,社会资本可能同市场化程度和正式制度有着相反的运动方向。

Based on the mechanism of social capital's influence on income gap of China's peasant workers,this study divides new social capital of peasant workers into two types,namely emotional type and instrumental one.The paper uses Shapley Value Decomposition method to empirically analyse the relationship between different types of social capital and the income gap of peasant workers.The results show that the instrumental type of new social capital has a certain influence on peasant workers' income and income gap,and the main cause of this influence is the unbalanced distribution of instnimental social capital.In the eastern region with better marketisation and higher economic development,social capital as an informal institution has significantly less impact on their income gap than that in the relatively less developed central region.Social capital mavbe has an opposite direction to the degree of marketisation and formal institution.
