Bibliometric review about eco-cites and urban sustainable development: trend topics

The world is undergoing exponential urbanization, with consequences for society in general, both for cities and people, with serious economic, social and environmental implications. Therefore, it is crucial to reconsider urban models of cities, to ensure global, long-term sustainability. Numerous researchers have argued that one of these models involves eco-city projects, and this study aims to carry out a systematic review of the literature on this topic, through bibliometrics. To do so, the Smarter, Prisma and Vantage Point methods were used, reflecting the originality of the study. The results obtained show that China has aroused researchers’ interest regarding its eco-city projects, with most studies being empirical, and so this study complements them. The main contribution of this research lies in identifying the keywords most used by authors, these being eco-cities, sustainable cities (cluster 1) and eco-cities, China, sustainable urban development and eco-cycle model (cluster 2). Finally, implications for theory and practice are presented, together with suggestions for future research.
