This article mainly answers the issue of the wage gap between urban and rural workers under multiple segmented labor market.Based on the baseline survey data of CFPS2014 and the Neumark and Brown decomposition methods, this study examines the wage gap and causes of urban-rural workers under multiple segmented labor market in China.As a result, it is found that wages in China's industry, ownership, occupation, and local urban workers are significantly higher than rural workers; Neumark's decomposition results show that 82.24% of urban-rural workers wage gap are caused by the individual characteristics, among which education is the main cause of labor wage gap, and 17.76% is caused by huji discrimination; Brown's decomposition shows that, regardless of industry, ownership, occupation, and regional division, the employment opportunity difference is not the main cause of urban-rural workers wage gap.What same work with different pay is the main reason for huji discrimination.This paper enriches the existing research in the following aspects:1) Using the Neumark and Brown decomposition methods to deeply analyze the impact of labor market multi-segmentation on urban-rural wage gap, from the perspective of individual labor characteristics and market discrimination for urban-rural workers.2) This paper uses micro data to investigate the difference between urban and rural workers' wages.It provides the most direct evidence for the impact of multiple segmentation of labor market on the wage difference of urban and rural household labor.
