Innovation ecosystems are characterized by the coordination mechanisms among diverse organizations around shared value propositions.This topic has become a significant academic issue in business management recently.This study reviewed the innovation ecosystems based on the quantitative analysis,and analyzed 1856 pertinent journal papers through bibliometric and content analysis techniques.The main findings include:Firstly,quantitative research on innovation ecosystems has identified three literature clusters related to corporate affiliation,technology connections and interaction mechanisms,with emerging related themes.Secondly,regarding quantitative measurements,both corporate affiliation and technology connections concentrate on ana-lyzing the composition and relationship dimensions,developing distinct quantitative methods in terms of nodes,indicators,and modeling techniques;and despite their differences,they converge in research methods at the interaction mechanisms level.Thirdly,this study proposed an integrated framework combining"corporate affiliation-technology connections-interaction mecha-nisms"within the innovation ecosystem's quantitative analysis.It highlights the importance of adapting between corporates and technologies during innovation,coordinating supply and demand to facilitate value creation and value capture through interactions.Reviewing the innovation ecosystem literature based on the quantitative analysis is an attempt to fill the current gap dominated by quali-tative rather than quantitative research and lack of quantitative reviews.This will suggest directions for future quantitative empirical studies on innovation ecosystems and offer insights for integrating theory into academic,commercial,and policy-making practices.
