Abstract: New public cultural spaces represent an emerging force in the delivery of public cultural services with Chinese characteristics. In recent years, these spaces have developed rapidly and closely aligned with the spirit of the 3rd Plenary Session of the 20th CPC Central Committee. They are expected to play a greater role during the 15th Five-Year Plan period. Shanghai attaches great importance to the construction of new public cultural spaces, incorporating them into the legal framework of public cultural services and embedding them in the broader layout of public cultural facility planning. A variety of types have emerged, including reading-theme, time-sharing, community-distributed, embedded-sharing and resource-product models. The successful practices of Shanghai in promoting the high-quality development of public cultural services include five major aspects: top-level design, legal guarantees, scientific governance, professional team building, and social development advancement. Drawing from Shanghai’s experience, the paper proposes ten recommendations for vigorously promoting the construction of new public cultural spaces: pragmatic positioning, top-level design, social operation, systemic support, distinctive development, intelligent technologies, scientific evaluation, child-friendly design, new-era cultural missions, and legal safeguards.
