Abstract: Promoting open science has become a global consensus within the academic community, yet China's practical implementation of open science remains in its nascent stage. This study begins with a comprehensive overview of open science concepts, implementation approaches, and supporting platforms. Through a case study methodology, it systematically examines the complete workflow of open science practices experienced by researchers, including specific open science activities and their respective platforms, and procedural challenges, such as intellectual property concerns. It identifies a spiral escalation model comprising three progressive academic research phases: Public engagement through citizen science, open access in academic research, and expert consultation for policymaking. This model demonstrates three interconnected academic research closed-loops and their corresponding feedback mechanisms within open science practices. Based on this case study, the paper aims to enhance researchers' and stakeholders' understanding of open science concepts and practical implementations, thereby addressing existing reservations and encouraging active participation in open science initiatives.
