Objective/Meaning Exploring the new era "cross-village joint construction" development model can help solve the problem of uneven and insufficient development among different villages in the region, and promote the comprehensive revitalization of rural areas and the construction of China-style modernization.

Methods/Procedures From the perspective of community theory, on the basis of field investigation, through literature research, analysis and induction, taking Changtai District of Zhangzhou, Fujian Province as a case, this paper explores the practice path and existing problems of the "cross-village joint construction" model, and puts forward corresponding policy suggestions.

Results/Conclusions The research shows that Changtai District, taking the effectiveness of the rural community as the starting point, innovatively reshaped the internal structure of the community with the organization joint construction mechanism, stimulated the development momentum of the community with the industrial joint development mechanism, exerted the functional value of the community with the governance linkage mechanism, and constructed a new model of cross-village collaborative development. However, in practice, there are still problems such as low degree of resource integration, weak support for development talents, and insufficient public service capacity of united villages. Therefore, suggestions on deepening the "cross-village joint construction" model are put forward from four aspects: stimulating main body development vitality, strengthening regional resource integration, improving talent service system, and promoting digital rural governance.
