Abstract: As the strategy of rural revitalization progresses, the planning and organization of individual villages have become inadequate in addressing the diverse and complex needs of current rural development. Consequently, synergistic development among villages has emerged as a crucial objective in promoting sustainable rural development. The concept of village cluster development facilitates the transformation of villages from 'standalone' entities to 'interconnected and integrated' entities, offering a potential solution to the dilemma of collaborative and sustainable village development. From a 'function-network' perspective, this paper takes Qingtang Township as an example. Firstly, based on the identification of rural geographical functions, we quantitatively analyze the network structure of the existing rural areas in Qingtang Township by refining the gravitational model and employing social network analysis. Secondly, techniques such as centrality calculation and cohesive subgroup analysis are utilized to delineate the cluster center and hinterland, supplemented by qualitative integration to determine different development types. Finally, planning applications are proposed at three levels: overall synergy, individual synergy, and elemental synergy, aiming to explore an innovative model for interconnected village development.
