Abstract: The green development of China's high-end manufacturing industry is of great significance for the sustainable development of the national economy. Taking the digital economy as the research background and thehigh-end manufacturing industry as the research object, this paper constructs agreen development evaluation index system by combining the characteristics of the high-end manufacturing industry, so as to describe the dynamic evolution process of digital transformation on the green development of the high-end manufacturing industry from the perspective of enterprise dynamic capability. The findings show that the digital transformation has a positive impact on the green development of China's high-end manufacturing industry. This conclusion is still valid after controlling the endogeneity and conducting a robustness test. The mechanism analysis reveals that in the process of digital transformation, the high-end manufacturing industrycan reduce resource consumption, cut down environmental pollution and promote green technology innovation mainlythrough the dynamic capability path of enterprises, thus promoting the green development of the high-end manufacturing industry. The regulatory effect reveals that sound internal control can positively adjust the relationship between digital transformation and green development of enterprises. The heterogeneity analysis finds that Digital transformation has a more significant role in promoting green development of the high-end manufacturing enterprises in the eastern region, where senior executives have financial backgrounds and where the two positions are separated. Therefore, it will empower China's high-end manufacturing industry to develop in a green way by widely applying digital technology tools to improve the green financial system, establishing a digital system management system to optimize the transformation environment, cultivating digital social capital to regulate enterprise resource allocation, and building a digital innovation network to reduce regional development differences.
