PurposeThe study proposes and evaluates a parsimonious research framework by integrating the major strategic theories related to an international firm's internal dynamics. This research's essence lies in the proposition that organizational competencies, knowledge resources and processes, absorptive capacity and innovativeness form the underlying base for sustainable competitive advantage in this dynamic world.Design/methodology/approachA cross-sectional explanatory research design is adopted. Using the quantitative data obtained from the sample of Indian international joint ventures (IJVs), partial least squares structural equation modeling (PLS-SEM) is deployed to confirm the proposed relationships among the research constructs. Finally, qualitative interviews helped in triangulating the primary survey's results.FindingsA well-established relationship between knowledge transfer and innovation is negated by the Indian IJVs' data, which is delved deeper with cross-industry qualitative analysis. The novel hierarchical model with multiple mediations has nurtured quite exciting results for the business world with some significant theoretical and managerial implications.Research limitations/implicationsThis study has investigated the nexus between multi-dimensional organizational competencies, knowledge transfer, absorptive capacity and venture innovativeness in the context of Indian IJVs. It has emphasized the role of internal dynamics in cross-cultural joint ventures to attain sustainable competitiveness through strategic and technological efficiency.Originality/valueThe study has addressed the specific research gap of under-investigation of dynamic capabilities and sustainable competitiveness in international joint ventures. It has investigated a complex model of multiple mediations, yielding interesting quantitative results with qualitative insights; which is rare to match in literature.
