In recent years, with the acceleration of globalization and the surging international situation, the traditional food system is facing unpredictable risks and impacts, and the development of local food system has reduced the local dependence on the global food system to some extent. The driving force behind this phenomenon, apart from the implementation of government policies, is undoubtedly local consumers and producers. This study uses Giddens' reflexivity as an analytical tool to explore the behavioral motivations and practice paths of different actors in the local food system. It is found that the consumers and producers in the farmers' market give full play to their individual initiative in a system restricted by "globalization". Starting from their own needs, they promote the various actors within the network to build a local food system containing multiple ideas. This set of behaviors is not generated by individual will, but is passively formed by the influence of local food culture, global knowledge transmission and manufacturing standards, so that local producers and consumers become a close link in the system.
