Abstract: Taiwanese lighting manufacturers are adopting sustainable operational processes from eco-design and searching for green materials in a dynamic environment. Hence, dynamic organizational capabilities and eco-innovation are necessary for sustainable development. Dynamic organizational capability primarily allows manufacturers to reduce the impact of eco-innovation and environmental changes. It might be possible to discover eco-innovation opportunities in the green markets by enhancing the dynamic organizational capabilities of a single firm. However, existing studies have not yet comprehensively assessed dynamic organizational capability and eco-innovation together in the Taiwanese lighting industry because of incomplete information. Hence, this study proposed interval-valued triangular fuzzy numbers to convert the experts׳ opinions into comparable measures and used grey relational analysis to facilitate and clarify the weights of eco-innovation under dynamic organizational capability. The results show that path-dependent learning is the top priority and that manufactures should consider opportunity-sensing capability and integrative capability simultaneously in the operational process.
