This book defines Business for Good as the strategic integration of social value into an enterprise's core competencies to realize commercial value through social progress. Unlike traditional charity's zero-sum redistribution of existing wealth, Business for Good moves beyond this mindset to advocate for profiting through altruism—enlarging the pie while distributing it more fairly.What happens when businesses stop treating social responsibility as an afterthought and instead make it central to their strategy? Can companies genuinely profit by doing good—not through charity or marketing stunts, but by solving real problems for real people? This book attempts to answer the above questions and more.Through the Business for Good Triangle Theory—encompassing co-benefit philosophy, institutional safeguards, and strategic integration—we offer tools that work across industries and company sizes. The Business for Good Action Map provides 35 actionable entry points spanning environmental, social, and governance dimensions, making sustainable practices accessible to everyone from startups to multinationals. These frameworks emerged from a decade of teaching and research at Cheung Kong Graduate School of Business, refined through thousands of student projects.Drawing on insights from behavioral psychology, this book features real-world cases from China and beyond: Patagonia's radical ownership restructure, Haidilao's employee empowerment model, accessible cable cars, and invisible office gyms. These examples demonstrate how small, well-designed interventions can trigger snowball effects of positive change, showing both successes and setbacks along the way.This book is for founders, executives, students, and anyone who believes commerce can be a force for progress. Business for Good isn't about choosing between profit and purpose—it's about recognizing they're fundamentally connected and building systems that make doing good the natural path to sustainable success.
