How does service-based education influence societal sustainability? Beyond product innovation, service innovation has been emerging as a paradigmatic issue for research. Human resource quality is one vital factor for service innovation. Service human capital development (i.e., education), however, has been relatively neglected in research on sustainability. This conceptual article discusses the chain of relationships between service learning and service climate, service innovation, and societal sustainability. In contrary to the widely spread concept of gaining competitive advantages through individual (organizational) service innovation, we emphasize the collaborative advantage that all individuals can construct together by service innovation to achieve sustainability. To achieve such a goal, the education for service human resources by service learning becomes a foundation. With these propositions, this paper contributes by offering possible future research issues, and by stimulating practice and policy discussions.
