Nowadays, the world is embarking on a process of transformation in the underlying dynamics of the digital ecosystem. With the aim of mitigating systematic cyber risks and reshaping the global competition landscape of digital industries, the developed countries are pushing the paradigm shift in the underlying dynamics of the digital ecosystems. Thorough research on this subject holds immense significance for boosting China's strength in cyber, digital, and intelligent development. Focusing on major developed countries, this study integrates literature reviews, intelligence analysis, and comparison study to investigate the essence, driving factors, primary objectives, and outlook of this shift. Drawing upon the fundamental principles of a paradigm shift, the study explores the core features of this underlying-dynamics shift, spanning aspects like mindset, methodology, practical norms, advancement strategies, security commitments, and ecological incubation models. Additionally, it delineates emerging trends, technological frameworks, and associated governance principles related to this paradigm shift. Challenges faced by developed countries' transformation strategies are discussed, along with the enabling advantages of China's endogenous security and safety (ESS) theory. The research puts forward five recommendations: (1) leveraging the first-mover advantage of the ESS theory to overcome limitations; (2) addressing pain points in critical areas of digital transformation; (3) maximizing the advantages of the large-scale domestic market by introducing more effective industrial policies to bolster novel paradigm shifts; (4) renewing the concept of personal training by cultivating responsible developers with "security-by-design" capabilities; and (5) enhancing the trustworthiness of Chinese digital products through technological innovation, thus facilitating China's Going Global initiative.
