Business Strategy and the Environment, EarlyView.ABSTRACT Environmental entrepreneurship and eco‐innovation, although cornerstones in the transition to a sustainable world, form a research nexus that remains largely understudied. We draw on the theory of complexity and the notion of cultural, temporal, and relational complexities to explain the process of eco‐innovation among environmental small ...
