Abstract: 【Purpose/significance】Analyze the information flow mechanism between different subjects in the tourism industry from the
perspective of value co-creation, improve the interpretation of information ecology theory, and promote the development of tourism in? formatization in the digital economy era.【Method/process】From the perspective of the information ecosystem, comprehensively use in? formation science, management and ecology theories and other related theories to construct a structural model of the tourism informa? tion ecosystem, and at the same time extract the factors affecting the operation of the tourism information ecosystem and establish re? search hypotheses, then construct a model and conduct empirical analysis of survey data through structural equations.【Result/conclu? sion】First, the interaction among people, information, and information environment in the tourism information ecosystem that inte? grates value co-creation is explained; then, the premise and mode of value generation in the system are discussed from the perspective of tourism demand and supply,and the whole process of value creation; finally, through empirical evidence, it is concluded that the tourism platform's capabilities and operating environment have a significant positive impact on user value co-creation behavior, and value co-creation behavior has a significant positive impact on platform co-creation value, which in turn affects tourism information Ecosystem operation.【Innovation/limitation】On the basis of constructing a tourism information ecosystem model, scientific data is used for in-depth research; however, the size of selected survey samples needs to be further expanded, and the theoretical model of system operation needs to be improved.
