Digital New Quality Productive Forces: The Key Driver of High-Quality and Sustainable Growth in the Global Economy

Digital new quality productive forces has emerged as a pivotal force in driving the contemporary economic transformation and upgrading.This study integrates Schumpeter’s theory of innovation with Romer’s theory of endogenous growth to systematically explore the impacts of digital infrastructure development, industrial digital transformation, and the integration of digital and real economies on high-quality economic growth.It highlights the pivotal role of digital new quality productive forces in enhancing total factor productivity(TFP),optimizing industrial structures, and promoting sustainable growth.The findings reveal that digital new quality productive forces not only significantly boosts economic efficiency through enhanced TFP and an innovation-driven approach but also provides essential empirical support for policymakers during the digital transformation process. Moreover,by promoting technological innovation and talent development, it facilitates continuous optimization and upgrading of industrial structures,thereby laying a solid foundation for achieving high-quality and sustainable economic growth.
