The changes in labor supply and demand are important factors affecting economic growth.The purpose of this paper is to predict and analyze the trends in China's labor supply and demand during the 13 th Five-Year Plan period and the longer period in the future.The scale and structure of the annual new entrants of labor force are predicted by accounting the numbers who are leaving from various stages of education.while trends of labor demand are predicted according to employment elasticity from the experience of industrialization of developed countries. The results show that, during the 13 th FiveYear Plan period.the scale of the new added labor would decrease slightly, with an average annual increment of around 15.68 million. At the same time.labor demand would increase steadily, with annually 15.42 million employment opportunities. Labor supply and demand would be roughly balanced; however,there would be increasing structural contradictions of the labor market.Based on the analysis of labor supply and demand,we provide an estimation of the unemployment scale of the 40's and 50's generations,migrant workers and college graduates,and discuss policy suggestions on promoting employment of college graduates.
