Abstract: [Abstract]　Traditional publishing organizations once paid attention to the development of App interactive single book， but did not achieve good results. To analyze the reasons， firstly， App interactive orientation is not conducive to mass content delivery， and it is also subject to people’s acquisition of soft rights and technical support. Moreover， the huge investment and the deviation of evaluation system make it lose its right to speak. In the external environment， single books are easy to dilute in the sea of products. Monopoly of distribution platforms and ambiguity of access standards make it difficult to highlight the advantages of high-quality content App books. Consumption habits also hinder the spread of books. Making a single book simply by translating knowledge does not constitute a growth point for publishing organizations. To get out of the “walled garden”， we must consider the socialization of content， fragmentation of knowledge and cross-border cooperation.
