Abstract

The research question of this article is how to introduce alternative technologies that enhance social welfare. To answer this question, we analyzed the cases of introduction of alternative technologies in a transportation sector. They are six local activities that promote car sharing, biodiesel fuel and light rail. As a consequence, we identified three-stage niche strategy that consists of niche creation, niche management and niche extension as a common tendency among the six cases.
