In the new era,the role and planning strategies of new towns are evolving in response to the challenges posed by megacities(including megacities and metropolitan areas,hereinafter referred to as"megacities").Drawing upon theoretical concepts such as Garden City,polycentric urban region,global city network,and"space of flows",this paper reviews the process of new town development both domestically and internationally to explore their foundational and strategic significance and interprets emerging trends.On the one hand,new towns continue to serve as"anti-magnetic centers",alleviating population and industrial congestion in central areas of megacities.On the other hand,the roles of new towns are evolving into"regional node cities".In light of this,the paper concludes by exploring the new understanding of new towns and planning strategies in the new era.Since megacities are often characterized by global connectivity and advanced production and service industries exhibit both clustering and dispersion trends,these industries can be distributed across different hierarchical centers.Certain new towns,serving as sub-centers of megacities,can thus emerge as node cities within global/regional productive service networks.Therefore,it is crucial to proactively design and guide the functional evolution of new towns in the new era,thereby enhancing their dual role as anti-magnetic centers and regional node cities.
