Public-Private Partnership（PPP）model are an important mode of infrastructure investment and financing. Since 2014，PPP in China has experienced a development process of fanaticism，calmness and standardization. In recent years，PPP talents training emerged at the historic moment，and many universities have set up professional courses or training systems. By reviewing the evolution and international practice of multi-disciplinary PPP and interdisciplinary education theories，and taking a PPP dule-degree programme in a university as an example，this report proposes that PPP curriculum should not be a simple “combination”，but should adopt the “trinity” education concept of knowledge，value and skills. Also it is important to integrate the knowledge of public administration，business administration，project management，project management，law and finance，and train more interdisciplinary talents in the new stage of “normalizing and orderly promoting the cooperation between government and social capital”.
