This document discusses emerging industries, open innovation, and innovation policies to support emerging industries using open innovation approaches. It defines emerging industries as new industries in the earliest stages of development involving new technologies. Open innovation is described as combining internal and external ideas and pathways to market. The document proposes that innovation policies aim to promote open innovation projects between firms, universities, and pioneers of new technologies in order to identify and develop promising new industries, rather than trying to predict specific industries. This approach could help emerging industries form through collaboration and pooling of resources.
