[Purpose/significance] The digitization of public culture is one of the main elements of the national cultural digitization strategy and a key issue for a sound modern public cultural service system. [Method/process] The article systematically compares the guidelines and tasks proposed by the National Culture Digitization Strategy, and further fo? cuses on the current construction logic of public culture digitization, pointing out that the current public culture digitiza? tion ecology composed of two types of institutions is somewhat alienated. [Result/conclusion] The author points out that the development of a national cultural digitization strategy provides an opportunity for the ecological transformation and adjustment of public culture digitization, but at the same time brings more challenges, and that the introduction of "re? sponsible innovation" into this issue may promote the healthy and sustainable development of public cultural digitization.
