Abstract: With the decrease of Public Library funds, the cultural and creative industries are becoming more and more important to the hematopoietic function of libraries. Taking the sales situation of the National Library Online store, the national library cultural and Creative Products Development Alliance online store and the Palace Museum online store as a microcosm, through SWOT analysis, this paper analyzes the fundamental reasons for the predicament of the literary and creative industry of Public Libraries: Imitating the cultural goods as the core of the cultural and creative industry of museums, and ignoring the market advantages of its own cultural services. This paper puts forward that in the era of paying for knowledge, libraries should innovate backward ideas and make great efforts to build cultural and creative industries with paid cultural services as the core, and we should standardize the types of services and revenue use and encourage libraries to develop paid cultural services.
