市场化程度与社会网络的收入效应——基于农民工数据的实证研究

The Degree of Marketization and the Income Effect of Social Network : Empirical Study Based on Rural Migrant Workers

文章基于中国2010年22个省(市)的农民工数据,实证研究了市场化改革对社会网络收入效应的影响。研究结论显示,随着市场化改革的不断深入,社会网络的收入效应呈现减少的趋势,即市场化程度上升1个单位,社会网络的收入效应将下降0.3个百分点。然而在体制内部门,社会网络机制的作用却越来越强,这在一定程度上表明体制外部门的市场化改革较为顺利,体制内市场化改革的阻力仍然较大——市场化程度每上升1个单位,体制内部门的社会网络收入效应会增加0.7个百分点,改革没有达到预期的理想效果。

Based on the data of rural migrant workersin 22 provinces or cities in China, this paper empiricallystudies the effect of marketization reform on the income effect of social net- works. The regression results show that with the constantly deepening mar- ketization reform, the income effect of social networks has a decreasing trend, namely the increase in one unit of marketization degree leads to the decrease in the income effect of social networks By 0. 3%. But in state- owned or collective firms, the role of social networks is more and more strong, showing that the marketization reform in private firms is smooth and the resistance of marketization reform in state-owned or collective firms is still great, namely the increase in one unit of marketization degree leads to the increase in the income effect of social networks in state-owned or collec- tive firms by 0. 7%, and the reform does not achieve the desired outcomes.
