Abstract: Based on the perspective of the academic and political roles of university think tank experts, the article explains the collision and conflict of university think tank experts in their academic roles and political ones. Academic and political roles are interactive and inverse. When the think tank experts are involved in the academic and political interaction without limits, the role images will be damaged. When the academic and political roles are "mutually exclusive", the political role is fulfilled while the academic role is shelved. After all, the academic role is the foundation of university think tank experts. It is suggested that the university think tank experts, playing a political think tank role, should have a warning line. To this end, the university think tank experts between the academic and political roles should adhere to the principle of value neutrality, appropriate blending, keeping distance, keeping the balance, so as to avoid confusion and conflict of roles.
