Abstract:Single innovation behavior obviously cannot meet the needs of sustainable and high-quality development. To promote the green and high-quality development of China's economy, it is urgent to explore the relationship between digital economy and regional green and high-quality development from the perspective of dual innovation. Select the panel data of 30 provinces in China from 2011 to 2020, integrate digital economy, technological innovation and regional green high-quality development into the dual innovation framework for regression, and find that digital economy is the core driving force to promote regional green high-quality development; Build a new pattern of green and high-quality development through the intermediary role of exploitative innovation; Achieve new results of green and high-quality development through the non-linear influence of interaction with exploratory innovation; There is driving heterogeneity in regions with low economic development, high industrial structure transformation and strong environmental regulation. At present, the key task of promoting regional green and high-quality development is to fully tap the synergistic driving role of digital economy and dual innovation, which requires the dual innovation needs of service enterprises to accelerate the deployment and improvement of new information infrastructure; Implement dynamic and differentiated digital economy strategies to release its development vitality in regions with high-level economic development, low industrial structure transformation and weak environmental regulations; Science and technology enterprises are encouraged to choose effective innovation ways, and form a strong synergy of digital economy and dual innovation in optimizing regional green and high-quality development.
