A widespread social concern has been caused by the corruption with high frequency in universities in recent years. Only by providing against possible trouble,can incorruptibility risks be controlled and reduced. Both motivation and opportunity are the central factors leading up to corruption. Opportunity is the external cause. It comes into existence because of the loss of restriction system for the authority. Motivation is the internal cause. It can be translated into action because of the collapse of ideological and moral defence lines. Earlywarning to the power operation not only relies on the system building and supervision with technological means that can reduce corruption opportunity, but also relies on the culture infiltration that can firmly construct ideological and moral defence. It’s the key element in preventing incorruptibility risks efficiently to strengthen the system construction, raise the incorruptible consciousness and create the easy supervision environment. The earlywarning and prevention mechanism of incorruptibility risks based on system, culture and technology, that can combine binding force of system, persuasive power of the education and balance power of supervision, gives us satisfying choice. Only by ramming the cornerstones of system building，supervision with technological means and culture penetration，can we achieve the goal of preventing and controlling corruption from fountainhead from our study.
