In recent years, with the frequent occurrence of the plasticizer incident, the research of plasticizer migration and its migration law becomes a hot research topic. In this paper, the research of determination of plasticizer migration and its migration model at home and abroad is reviewed. The research of determination of the migration assay is divided into two categories: the research of innovative experimental methods and the error analysis of experimental measurement results. According to the mathematical models adopted by research, the important documents of such three categories as Differential Equations、Statistical Model and Computer Simulation are briefly reviewed. The research progress of determination of plasticizer migration and its diffusion and transport model is prospected.
