Abstract: This paper uses the “ employer-employee” matching data of Nanhai District, Foshan City, Guangdong Province in 2013 and 2016, and uses the estimation method of propensity score matching and instrumental variables to empirically test the influence of union membership on the wage rate of migrant workers and the differences between two generations of migrant workers, followed by the exploration and analysis of the mechanism. It is found that after the wage premium effect of union membership is decomposed into coverage effect and membership effect, the impact of coverage effect hardly exists, and the influence of membership effect has inter-generational differences, which is only significant in the new generation of migrant workers. Further study finds that the non-existence of the coverage effect is mainly due to the fact that the union fails to carry out collective bargaining. The inter-generational difference of the membership effect is due to the different behavior orientation of membership caused by different demand levels of two generations of migrant workers. The findings of this paper will help company trade unions to solve the wage problem of migrant workers, establish a long-term wage growth mechanism for migrant workers, and provide a reference for enterprises to build harmonious labor relations and implement diversified human resource management strategies.
