The emerging service industry has grown out of the transformation of traditional services and is characterized by the application of new technologies and platform-based operations. Given that the production and delivery of the industry depend heavily on technical rules and platform systems, the development of high-end standards becomes a critical issue that bears directly on national systemic security. Focusing on intelligent equipment for the digital culture, digital content generation, digital trade services, and smart city platform services, this study examines the security risks arising from missing standards, delayed updates, and inadequate implementation. Starting from the service forms of each field, it identifies the key links at which high-end standards matter and the resulting security consequences, and groups the risks into four categories: technological self-reliance, industrial ecosystem security, public service operations, as well as international rules and market access. The study finds that China's emerging service industry has already developed a substantial market scale and a strong foundation for engineering applications, but it still lacks self-reliance and rule-setting influences regarding critical architectures, core interfaces, as well as evaluation and certification. Typical cases, such as labelling rules for artificial intelligence generated content and content provenance credentials formulated by the Coalition for Content Provenance and Authenticity (C2PA), demonstrate that once high-end standards are incorporated into such key links as platform interfaces, certificate trust systems, and testing and certification processes, their influence can extend from individual technologies to industrial collaboration, public service operations, and access to international markets. To improve the governance of high-end standards in the emerging service industry, this study recommends strengthening the self-supply of critical high-end standards and aligning standards development with technological research and development. It also proposes the establishment of a standards testing alliance to improve reference implementations, shared test datasets, testing and certification, and certification recognition mechanisms, thereby supporting industrial collaboration and cross-platform compatibility. Moreover, a dynamic review and resilience assurance mechanism should be established throughout the lifecycle of critical service systems, with a focus on strengthening switching and disaster recovery testing, and aligning financial support with implementation outcomes. Additionally, it is essential to coordinate participation in international rule-making and market access arrangements while preserving independent technical options and backup interfaces, and enhancing necessary security reviews.
