The landscape of digital publishing is experiencing a fundamental transformation driven by unprecedented technological advancements. Central to this transformation is the concept of "digital affordance," which serves as the theoretical foundation for age-friendly digital publishing initiatives. In the new era of media convergence, the development of age-friendly digital publishing inherently reflects the evolution and transformation of digital affordance. China's demographic shift toward an aging society, resulting from an imbalance between birth and mortality rates has prompted the government to prioritize the adaptation of digital technologies for elderly citizens. Various governmental departments have implemented policies and initiatives to enhance digital technologies beneficial to the elderly. These measures provide both a policy framework and valuable research cases essential for this study's development and reasoning. Through case analysis, digital affordance emerges as a robust framework for identifying challenges in China's age-friendly digital publishing landscape. This paper delves into digital affordance through three dimensions: social affordance, portable affordance, and productive affordance. Through empirical analysis, it demonstrates digital affordance as an effective lens for studying age-friendly digital publishing. This perspective enables a comprehensive analysis of the current state and future direction of age-friendly digital publishing in China. The analysis reveals three major issues: excessive openness in content creation, inadequate adaptation of technical affordance, and limitations in stakeholder affordance within age-friendly digital publishing. The paper examines the underlying causes of these issues to develop a deeper understanding of the development process and its associated challenges. Based on case studies and international best practices, this paper presents strategic recommendations to address the identified obstacles in age-friendly digital publishing development. These strategies encompass strengthening digital affordance to reinforce the age-friendly digital publishing production chain, utilizing artificial intelligence and other emerging technologies to create new growth opportunities for the age-friendly digital publishing industry on the whole, and enhancing industry governance to foster sustainable development. These strategies aim to establish a more user-friendly and accessible digital service system for elderly users while creating new opportunities for China's age-friendly digital publishing industry. The long-term outlook for China's age-friendly digital publishing industry remains positive. Through continued policy optimization, implementation of supporting initiatives, and multi-stakeholder collaboration, the industry is positioned to enhance the digital experiences of elderly users while fostering a society that emphasizes humanistic care and social values.
