Abstract: Professional degree has become one of the main degree types in China. Professional degree postgraduate education in developed countries such as the United States, Britain, France, Germany, Japan and South Korea has been developing for a long time. Summing up their experience and development trend will provide important reference for the sustainable development of professional degree postgraduate education in China in the future. Therefore, by using the international comparison method, this paper studies the international trend of professional degree postgraduate education, and finds that professional degree postgraduate education has the basic characteristics of increasing cognitive tolerance of professional degree, reasonable structure, continuous expansion of scale, stronger certification culture, deeper integration of production and education, and more standardized setting process. It is proposed that the sustainable development of professional degree postgraduate education in China should expand the scale of professional degree postgraduate education, promote the certification culture, promote the construction of quality assurance system, and pilot the deep integration of production and education training mode which is represented by "modern apprenticeship".
