Abstract: 【Purpose/significance】This paper analyzes the implementation mechanism and promotion strategy of the indus⁃
try information service fusion in the open network environment, and provides reference for the implementation and top-lev⁃
el design of the industry information service fusion.【Method/process】Firstly, the general framework of industry information
service fusion in the open network environment is established, and the implementation mode of service fusion is discussed
in different scenarios. Then, the paper analyzes the promotion strategy of industry information service fusion.【Result/con⁃
clusion】In the open network environment, industry information service fusion can be regarded as a hierarchical structure
composed of resource layer, service layer, composition layer, UI layer and quality control mechanism. The specific mode of
service fusion can be classified into four modes: request-response mode, linear multi-stage mode, parallel multi-stage
mode and mixed multi-stage mode. In terms of promotion strategy, we should start from three aspects: building open service
fusion platform, promoting open service standardization, and promoting open information service fusion automation.
