The observation of the experimental bases of public cultural policy research shows that since 2017，China's public cultural policies have been intensively introduced with the core goal of promoting the construction of modern public cultural service system，focusing on such aspects as the construction of modern public cultural service，improving social participation in public cultural service system，accelerating the digitization of public culture，and accelerating the construction of a rural public culture service system，etc.Driven by the national cultural policy，the service efficiency of public cultural institutions such as museums，libraries，cultural centers，and cultural stations has been continuously improved.However，it has also been observed that some public cultural institutions have problems，such as weak public cultural infrastructure construction，a slight decline in input and output performance，loss of professional talents，and financial security methods and standards to be improved.It is recommended that implement the policies and regulations for the construction of public cultural service systems should be further implemented，performance evaluation and innovation of financial input methods need to be strengthened，and promoting corporate governance and digital construction of public cultural institutions should be the focus of work.
