Most studies on innovation capability analyze the firm level. Little efforts have been made to understand the interactions that take place in inter-organizational agglomerations and the capabilities that such arrangements retain. This study aims to develop a theoretical framework of cluster innovation capability. The academic production about innovation capability of clusters in the business field from 2005 to 2014 was analyzed and the databases consulted were: EBSCO, SCOPUS, and Web of Knowledge.311 items were cataloged, 144 were available in full text, and among those 18 papers were selected. The cluster innovation capability was structured based on a theoretical framework through qualitative content analysis. Thus, acquisition capability, diffusing capability, and knowledge management capability are the main capabilities that constitute the cluster innovation capability.
