Enterprises engaged in supply chain operation services carry out value innovation and continue to deepen, and then gradually integrate retail, finance, information, logistics and other industries to upgrade to platform-based enterprises, and then rely on the internet to build a platform ecology for the supply chain industry. Based on the theories of value chain, value net, value co-creation and platform ecology, with the application of exploratory and case study methods, by interpreting the evolution path of value innovation in supply chain and referring to the architectural framework of industrial platform, and based on the perspective of platform ecology and value co-creation, this paper studies the ecological model of supply chain industrial platform from three dimensions: constructing the model of supply chain industrial platform, analyzing the operating mechanism of the platform and analyzing the value co-creation system of the industrial platform. The research results show that the construction of the industrial platform ecological model needs to follow the system mechanism of value cocreation; the formation of supply chain industrial platform ecological model needs to constantly integrate and create the system elements of platform ecology; the operation of supply chain industrial platform ecology needs to continuously integrate the resources of other industrial platforms; the deepening development of the supply chain industry platform ecology needs to take into account the ecological environment of the industry platform.
