Social dilemma for 30 years: Progress, framework, and future based on CiteSpace analysis

Social dilemmas have been a popular research topic in the past 30 years, yet there is still a lack of interdisciplinary reviews. This study represents the first attempt to conduct a bibliometric analysis of social dilemma research over the past 30 years, aiming to identify the research status, research hotspots, and future trends in this domain. We conduct an interdisciplinary analysis of 3630 articles from 1993 to 2023 using CiteSpace software. We find that: (1) this research domain exhibits a fluctuating upward trend and possesses evident interdisciplinary characteristics. (2) Collaboration among authors, institutional and regional, is much more prevalent, especially in the evolutionary dynamics of human behavior, cooperation, and reinforcement learning. (3) The current hot trend in this field of research is to investigate the influencing factors and solutions for social dilemmas. Researchers have shown great interest in value orientation, social norms, fairness, punishment, and rewards in promoting cooperation. (4) In the future, this field will cover different disciplines, develop theoretical frameworks grounded in bounded rationality, explore the boundary conditions of effective strategies, and integrate emerging technologies. This study serves as a valuable reference for scholars seeking to navigate social dilemma research while also providing insights for managers aiming to devise practical solutions to social dilemmas.
