The social and cultural activities this paper will discuss are a public service activity(free) catering to the public which are mainly held by the government. These services, which are the basic content of the public cultural service system, mostly rely on basic public facilities such as public library, cultural centers and museums, etc. The key solution to the problems of basic public facilities construction(such as funds investment, management, talent team construction, etc)is to establish the security mechanism and the performance evaluation mechanism, rather than assess on social culture (public culture) service units. This paper mainly focuses on how to establish security mechanism for county libraries and cultural centers, and to provide suggestions for cultural and financial departments. <<
