Sustainability-oriented innovations in smart cities: A systematic review and emerging themes.

The purpose of the paper is to clarify the relationship between sustainability-oriented innovations (SOI) and smart city development based on the systematic review of existing literature in the field. As an outcome of the review process, 159 articles were carefully selected for the in-depth analysis of the inter-linked concepts of smart city and sustainability-oriented innovations. The results show a growing trend of research papers in this field, especially in the last five years. The findings show the significance of a systemic multi-dimensional view of innovations for the smart sustainable development of cities. We have identified four main perspectives through which the scholars discourse the SOI dimensions in the smart city context: technology perspective, organizational perspective, social innovation perspective with citizen engagement, as well as system-level changes with innovation ecosystems. Second, we have recognized various focused themes under each main perspective. The various types of innovations also have impacts on different components of smart cities. Although the technological innovation perspectives dominate, and governance aspects are also paid attention to in recent studies, the increasing amount of research outputs also report on the developments of other components and perspectives, such as new human-centric approaches like citizen engagement. • Growing trend in papers connecting sustainability innovations and smart cities • Four main perspectives of innovation dimensions in smart cities recognized • Technological and governance perspectives dominate in earlier research. • Recent increase in research of human-centric approaches and citizen engagement [ABSTRACT FROM AUTHOR]
