Complexity Review of NIMBY conflict: Characteristics, Mechanism and Evolution Simulation

Complexity is an essential characteristic of NIMBY systems, and few studies have analyzed NIMBY conflicts using the theory of complex adaptive systems. From the perspective of complexity, this study re-examines the characteristics and evolution mechanism of NIMBY conflicts and draws the following conclusions: (1) NIMBY conflicts are a complex system of interaction between multiple subjects and the environment, characterized by aggregation, Linearity, dynamics, flow characteristics, and hierarchy. (2) Build a stimulus-response model for the evolution mechanism of NIMBY conflicts based on the theory of complex adaptive systems and consider that adaptability is the driving force for the evolution of NIMBY conflicts. The effector promotes NIMBY subjects to gradually adapt to changes in the external environment and maximize their interests. (3) Using Agent simulation technology to simulate the evolution mechanism of NIMBY conflicts, we found that how the government responds to conflicts is more important than the intervention time; Residents' communication efficiency and connection probability will affect residents' behavior choices； The lower the residents' communication efficiency, the less likely it is to form NIMBY conflicts， and stronger resident relations can accelerate residents' convergence to the exit state, affecting the evolution of NIMBY conflicts. This study deepens the understanding of NIMBY conflicts and provides a new reference perspective for the governance of NIMBY conflicts.
