This book presents a rigorous academic investigation into the digital transformation of public hospitals in China, drawing upon four in-depth case studies from leading tertiary hospitals in Shanghai--Ruijin Hospital, Zhongshan Hospital, Huashan Hospital, and the Sixth People's Hospital. The cases, selected into the five major international business case repositories (ChinaCases.Org, Harvard Business School, Ivey, European, and Japanese Business Case Centers), provide rare empirical evidence and analytical frameworks for understanding the strategic, technological, and organizational dimensions of digital transformation in large-scale public healthcare institutions. Notably, three academicians also contributed directly to the writing of this volume, further enhancing its scholarly depth and practical relevance. Beyond descriptive accounts, the book critically examines the design and deployment of digital platforms, AI-powered diagnostic systems, clinical data integration architectures, and governance models for patient-centric services. Contributions from renowned academicians, experts, and senior hospital administrators complement the case studies with theoretical perspectives and policy-relevant insights into digital infrastructure development, talent-system alignment, and the evolving role of public hospitals in the smart healthcare ecosystem. Positioned at the intersection of health economics, hospital management, and digital strategy, this book offers high scholarly value to researchers, graduate students (MBA, MHA, EMBA), healthcare policymakers, and practitioners. It serves as both a research-based reference and a pedagogical resource for advancing the theory and practice of healthcare digitalization in emerging economies.
