This book is the latest scholarly masterpiece in the field of corporate strategic management, launched by the author after years of dedicated research. In the current era of artificial intelligence and the new digital economy landscape, as the Chinese path to modernization and global sustainable development progress further, Chinese enterprises are facing historical opportunities and practical challenges stemming from the deep integration of digital transformation and sustainable development. Sustainable development, as the core of national strategy, inherently requires the coordination of its economic, environmental, and social dimensions, which resonates profoundly with the technology-empowering characteristics of the digital economy. Digital transformation is not only a key means for enterprises to cope with resource constraints and environmental pressures but also a core engine for reconstructing the creation models of economic value, environmental value, and social value. Against this backdrop, deeply analyzing how the digital transformation of Chinese enterprises promotes sustainable development through multidimensional mechanisms of economy (high-quality development, organizational resilience), environment (environmental performance, green innovation), and society (ESG performance) has become an important topic of theoretical and practical concern in the field of corporate strategic management.
