Constructing a green and harmonious cyberspace in a network content ecosystem is a beautiful vision for millions of netizens. This study, by establishing a self-compiled corpus of judicial discourse from digital platform typical cases in China and using a combination of corpus-based approach and case analysis method, represents the development status of the Chinese network content ecosystem in order to develop a model for understanding and evaluating a network content ecosystem. Based on the analysis results of Chinese judicial discourse, an evaluation model, namely the People, Object, Technology, Organization, Government, Environment Framework (POTOGE), is derived after examining and evaluating four conceptual frameworks of the People, Process and Technology Framework (PPT), the Technology, Organization and Environment Framework (TOE), the Real Access/Real Impact Framework (RA/RI) and the People, Technology, Organization and Environment Framework (PTOE). To some extent, the POTOGE evaluation model presents a holistic and comprehensive perspective for understanding and evaluating a network content ecosystem and its key components, which can provide a reference for testing standards to ensure the sustainable development of current and future network content ecosystems. Meanwhile, the insights obtained from this study may help deepen our understanding of the judicial discourse and its thinking in the network content ecosystem. The analysis results of typical cases on digital platform can provide a reference for the formulation of future relevant laws and regulations and improve the legal protection and prevention awareness of society.
