Innovation and Smart Cities Research: A Review and Future Directions

Abstract

This chapter aims to review existing evidence and map research on innovation in smart cities. Based on data from 822 articles and chapters, bibliometric analyses were performed to capture descriptive statistics and key themes of this field of research. The results of our descriptive analysis show that interest in this field of research is increasing, and substantial contributions have been made in the past 12 years. Moreover, the results from co-citation analysis show that innovation in smart city research is grounded in four clusters: open, urban, sustainable, and digital innovation. Key contributions within each theme will be discussed, and future research opportunities will be highlighted.
