Major science and technology project generally got high social expectations as a result of high investment. To ensure that the science and technology teams follow the norms of S&T research and make full use of the investment, the effective norms maintenance mechanism must be established which includes punishment for violators and burnout of teams of supervisors, namely setting up the meta-norm execution mechanism. It is very important to establish the effective major science and technology project evaluation system to reduce the norm and meta-norm execution cost. In this paper, the principles, methods and implementation system guarantee of evaluation system building are studied as well.
