With the acceleration of urbanization, towns, as vital entities for coordinating urban-rural development and facilitating local urbanization, have garnered significant attention from Chinese scholars in recent years. Among these towns, Hangjiahu towns, as one of the fastest-growing and most promising regions for town development in China, is intricately intertwined with the optimization and adjustment of their spatial forms, guided by policies that continually evolve and adapt. This study begins by elucidating the evolution of policies of towns in Zhejiang province, summarizing the key focal points of higher-level planning in different phases. Subsequently, it delves into an in-depth analysis of the morphological transformations and organizational stages of Hangjiahu's towns under the influence of policy directives. Finally, it synthesizes the spatial evolution characteristics from the past and provides insights into future trends in spatial organization, to offer a template for the development of towns not only in China but also in other regions worldwide.
