Abstract:Based on the perspectives of systems theory, industrial ecology theory and ecological niche, this study analyzes the evolution mechanism of the information technology industry ecosystem from three levels of industrial chain extension, organizational form transformation and application scenario transformation. " as the core, the progressive process of "line" pulling, "surface" combining, and then "ecological" linkage, to build an information technology industry ecosystem model that combines industry and internal and external circulation of enterprises. Then, based on the Huawei Kunpeng industrial ecosystem as an example, the process of system construction and application is explained in practice, and the theoretical model is verified. This study can provide a feasible reference and reference for my country to adapt to the changes of the information technology industry under the new situation, and rely on the integration of information technology and industrial ecology to accelerate the transformation and upgrading of the industry.
