Abstract This study involved a meta‐analysis of 506 estimates extracted from 75 studies to estimate the effect size of rural household registration ( hukou ) on wage levels. Our meta‐synthesis results indicated that the negative effect of rural hukou on wages is statistically significant; however, the effect size remains small in terms of the partial correlation coefficient. The results of the meta‐regression analysis and test for publication selection bias indicated that the differences in the wage effect of hukou among genders, corporate ownership sectors, and periods are insignificant. We also found that publication selection bias is unlikely, and genuine evidence exists in the literature.
