Although "Urban Memory Project" has been implemented for many years in our country, it still has the problems of the singleness of main construction body, shortage of social participation, etc. In order to change this situation, "Urban Memory Project" needs the government, functional departments and social forces to carry out extensive cooperation.

In order to achieve the unity of individual rationality and collective rationality, to pursue the great construction results, we can introduce the concept of the authoritative organization, repeated game and commitment.
