Digital technology empowers home-school-community collaborative education in preschool education, representing a new direction for paradigm innovation in the digital era and a key driver for advancing high-quality preschool development^[1]. In this process, digital technology plays a pivotal role in enhancing collaboration efficiency, strengthening consensus on co-education concepts, improving stakeholder interaction effectiveness, and optimizing institutional implementation mechanisms, thereby continuously refining the collaborative education ecosystem. However, current home-school-community collaboration still faces practical challenges such as fragmented value recognition, inadequate coordination among stakeholders, insufficient policy implementation, and lack of technical application ethics guidelines. To effectively address these issues and promote deeper integration of digital technology with collaborative education, the study proposes optimization strategies from multiple dimensions: Conceptual Guidance: Establishing digital co-education awareness, consolidating value consensus, and solidifying the ideological foundation for collaborative education; Capacity Building: Enhancing digital literacy cultivation, strengthening stakeholder capabilities, and improving collaborative education outcomes; Institutional Support: Establishing diversified institutional frameworks, refining operational mechanisms, and providing robust support for collaborative education; Platform Optimization: Developing standardized digital platforms, purifying educational environments, and creating safe, orderly collaborative education ecosystems.
