Abstract
This paper examines the issue of sustainable development of the region in relation to innovation. Sustainability has been discussed at various levels. This paper shows that when approaching the issue of sustainability from a managerial perspective, it is promising to study the issue on a regional basis. Theoretical examination was conducted by integrating the idea of collective impact into Kanai's (2012) model of regional innovation, which holds the key to sustainable development. Through this examination, it became clear that an entrepreneurial platform capable of involving people from diverse sectors and developing effective interactions plays an important function in approaching the ambiguous and complex issue of regional sustainability. The role of entrepreneurial platforms (Entrepreneurship II) in regional innovation can be thought of as a mechanism that brings together diverse dispersed knowledge, increases the potential for new combinations through new interpretations, and promotes innovation (Entrepreneurship I). In other words, by autonomous interaction among diverse actors through dialogue and practice, platform creates new practical knowledge as a base for innovation and stimulates entrepreneurship by reducing ambiguity and uncertainty. It functions as a mechanism to promote innovation by attracting potential entrepreneurs interested in the agenda and making entrepreneurs visible, thereby increasing the potential for resource mobilization.
