Abstract: Women's post-maternal employment status is an important factor contributing to gender inequality in labor market. Previous research mainly considered employment as a static and single event, lacking a dynamic life course perspective. Using the 2014 China Health and Retirement Longitudinal Study (CHARLS) data, this study applies sequence analysis for the first time to depict a period of twenty-one years of non-agricultural working women's employment trajectories before and after their first childbirth. We divide the sample born between 1940s to 1970s into different birth cohorts to cover three stages of labor market transformations in China:the early days of the PRC, the early stage of market reform and the mature stage of market reform. Results show six typical trajectories of women's post-maternal employment in China. They are:long-term regular employment (55.06%), early return to employment (8.69%), late return to employment (3.98%), self-employment or from employment to self-employment (19.78%), long-term unemployed (8.07%), and long-term informal employment (4.42%). Different employment trajectories reflect clearly the heterogeneity of female group characteristics. Our results also show that with the social changes, the complexity and diversity of Chinese women's employment trajectories have increased significantly, showing that more women frequently switch between multiple employment status. It can be seen from the trajectories of different cohorts that the proportion of women who are able to maintain full-time employment has significantly decreased, while the proportion of self-employed, part-time and non-employment trajectories have increased noticeably. In addition, human capital, institutional patronage, and shared childcare responsibility have significant positive effect on women's full-time employment. Nevertheless, with China's marketization, the protection provided by these factors have substantially weakened over cohorts.
