The China Labor-force Dynamics Survey (CLDS), launched by Sun Yat-Sen University, is the first national longitudinal social survey targeted at the labor force in China. Using a rotating panel design, the survey is conducted every two years and has accumulated three waves of data now. In this article, we introduce the theoretical background, sample design, and implementation of the survey. We also summarize some scholarly themes which CLDS can be applied to by presenting descriptive statistical results.
