The industrial Internet is increasingly active and has become an important carrier for regional innovation,while current research has not paid enough attention.This paper proposed the concept,connotation and inner structure of the industrial Internet ecosystem,and constructed the indicator measurement approach from enterprise participation,industrial application and regional support.Using the provincial data from 2012 to 2021 as research sample,this paper explored the impact and mechanism of in-dustrial Internet ecosystem on regional innovation capability.It was found that the industrial Internet ecosystem can effectively promote the regional innovation capability,among which the impact of industrial-level factors is the most significant.From the spatial perspective,the impact of industrial Internet ecosystem on regional innovation capacity presents significant differences,and presents a decreasing trend of"Eastern-Central-Western-Northeastern regions".From the perspective of transmission mecha-nisms,the industrial Internet ecosystem helps to enhance human capital level and technology market activity,and thereby enhan-cing regional innovation capability.The research will provide theoretical references and practical insights for constructing indus-trial Internet ecosystem and smooth flow of innovative elements to enhance regional innovation capability.
