How to Support the Decision-Making Process of Community Regeneration in Megacities Based on Evolutionary Game——A Case Study in Shanghai

Abstract

AbstractUrban regeneration is an inevitable trend at a certain stage of urbanization, and as the basic unit of the city, how to develop suitable regeneration participation mechanisms and strategies has become an important issue, especially for the comprehensive design and management of integrated strategies to promote internal drive so that it can operate on a regular basis. The problem is systemic and complex, with different stakeholder cooperation mechanisms driven by different actors in the government-led, market-led and co-production models of participation and community planner participation models. Game theory has gradually become an important tool for delineating and studying interest groups, but simulation of game processes and derivation of outcomes based on participation mechanisms have not yet been applied in community regeneration. Moreover, using only case studies will have a long practice cycle with large economic and social impacts, and lacks reasonable and efficient experimental support. This study uses an evolutionary game model to explore the impact and association of different types of community regeneration participation patterns under various benefit reward and punishment strategies. Based on this, a system dynamics model is developed to analyze the dynamic changes of the multi-party competition in typical situations with the help of data simulation, and to explore the promotion of the balance between the reward and punishment strategies under different participation patterns, to achieve the strategic optimization for sustainable development. The expected research results will not only enrich and improve the theory of urban regeneration, reveal the influence mechanism of the dynamic cooperation strategies of different stakeholders in regeneration, but also provide scientific basis and technical support for decision making in fine urban governance and organic development, thus this project has important theoretical and practical value.KeywordsCommunity regenerationParticipation mechanismsEvolutionary game theorySimulationDecision-making support
