Abstract: 【Purpose/significance】This paper aims to explore the impact of big data environment on the ecological development of orga⁃nizational knowledge innovation,so as to adapt to the new situation and new needs of knowledge innovation,knowledge ecosystem con⁃struction and knowledge economy development in the era of big data【. Method/process】Based on the ecological theory,this paper ana⁃lyzes the basic research components of knowledge ecosystem and big data ecosystem,so as to provide a basic reference for the study of knowledge innovation ecology driven by big data.【Result/conclusion】The basic concept of big data-driven knowledge ecosystem is put forward,and the components of the system are listed.The new characteristics of knowledge ecosystem embedded in big data culture
are analyzed.Based on big data,knowledge ecosystem theory and knowledge ecosystem model,the theoretical model of the system is constructed,and the operational evolution mechanism is studied【. Innovation/limitation】Integrate big data resources and technological environment into knowledge management research from an ecological perspective.
