The boundaries of economic and social attributes of technology-based platform enterprises are more blurred in the platform ecological field, and the paradigm of social responsibility practice and governance mechanism have produced new changes, which require an in-depth analysis of their logic of origin, practice paradigm and governance mechanism. This paper takes Meituan-Dianping, a widely influential technology-based platform enterprise among platform enterprises, as the research object, and explores the definition of its social responsibility in depth to further explore the issue of social responsibility governance mechanism of technology-based platform enterprises. The study finds that the social responsibility of technology-based platform enterprises can be hierarchically divided according to their roles as ‘independent operating entities’, ‘business operation platforms’ and ‘social resource allocation platforms’. and ‘social resources allocation platform’. A contextualized governance mechanism centered on corporate value, a cross-level network governance mechanism, and an iterative ladder governance mechanism are formed to promote the goodness of science and technology.
