This monograph establishes a pioneering analytical framework to examine China’s low-carbon transition through the synergistic interaction of financial innovation and technological empowerment. By integrating green finance, digital infrastructure and green credit policies with the rapid advancement of Artificial Intelligence (AI), the monograph offers a comprehensive understanding of the mechanisms driving sustainable development. At the macro-urban level, this book demonstrates how financial innovation catalyzes AI adoption, yielding measurable improvements in energy efficiency and significant reductions in carbon intensity. At the micro-enterprise level, this book reveals how technological empowerment directly reduces energy intensity through digital technologies, with financial innovation further amplifying this impact via targeted credit mechanisms that incentivize exploratory innovation and ESG integration. By resolving the “dual-impact paradox” of technological solutions and quantifying multi-scalar policy efficacy, this book provides emerging economies with an empirically validated blueprint for synchronizing financial systems, digital disruption, and hierarchical governance in the global climate transition.
