Accelerating the development of Industrial Internet is conducive to the transformation and upgrading of China's manufacturing industry and improve international competitiveness. In order to build a universal industrial Internet model suitable for large, medium, small and micro enterprises, the "Industrial Internet Ecosystem Model (IIEM)" is proposed, including the dimensions of entity dimension, resource dimension and digital-knowledge dimension, named "three-dimensional and six-layer" spatial model. And the operation mechanism of IIEM is described. In the convergence process of entity flow and resource flow, and in the process of product delivery and value realization bearing market demand, the synergy and enabling mechanism of digital-knowledge flow has been brought into full play. And digital-knowledge flow shows the value of data as a new production factor at different levels and dimensions of IIEM, explains the basic logic of improving the intelligent level of enterprise production system and delivered products, and also expounds the basic path of digital transformation. IIEM emphasizes industrial attributes, clarifies the basic principles and elements of the Industrial Internet Ecosystem, and its internal mechanism of promoting industrial and industrial development, and the views of bit based, semantic associated, model reused, knowledge gathered into wisdom is proposed, which will help enterprises deeply understand the evolution and realization path of Industrial Internet, and is conducive to the implementation and popularization of Industrial Internet Ecosystem.Keywords: Industrial internet; ecosystem; model; digital-knowledge flow; dynamic value flow.
