工业互联网是推动工业高质量发展的重要引擎，加快发展工业互联网，有助于我国制造业转型升级，提高国际竞争力。为构建适用于大、中、小、微企业的工业互联网模型，本文在对国内外工业互联网模型进行分析的基础上，运用系统分析方法，创新性地提出了由“三维四流六层”空间结构构成的工业互联网生态系统模型。本文分析了工业互联网生态系统模型的运行机理，即实体流、资源流、数智流及动态价值流运行机理，其中数智流展现出了数据作为新型生产要素在该模型不同层级、维度的流动价值，说明了企业生产系统和交付产品的智能化水平提升的基本逻辑，同时也阐明了数字化转型的基本路径。工业互联网生态系统模型强调工业属性，通过案例实证研究，本文验证了该模型在助力企业深刻认知工业互联网演进及实现路径、融入工业互联网平台的有效性。

Industrial Internet can drive the high-quality development of industries, and accelerating the development of industrial Internet is conducive to the transformation and upgrading of China’s manufacturing industry and to the improvement of its international competitiveness. To build an industrial Internet model that is universally adapted to large, medium, small, and micro enterprises, this study analyzes the existing industrial Internet models in China and abroad, and proposes an industrial Internet ecosystem model (IIEM) composed of three dimensions and six layers. Additionally, the operation mechanism of IIEM is presented in terms of entity, resource, digital intelligence, and dynamic value flows. Digital intelligence flow exhibits the flow value of data—a new production factor—at different levels and dimensions of IIEM, which explains the basic logic for improving the intelligent level of enterprise production systems and delivered products and expounds on the basic paths of digital transformation. IIEM emphasizes industrial attributes. Furthermore, the effectiveness of IIEM in assisting enterprises to understand the evolution and realization paths of industrial Internet and to integrate into the industrial Internet platform is verified through case study.
