Abstract:in the era of emphasizing high-quality economic development and soft power competition of enterprises, green technology innovation has become an important way for start-ups to open the market and seize the competitiveness. Based on the panel data of China's gem enterprises from 2009 to 2019, this paper divides green technology innovation into two dimensions, and deeply explores the mechanism of radical green technology innovation and incremental green technology innovation on enterprise growth and the regulatory role of organizational slack. It is found that the positive impact of radical green technology innovation on enterprise growth is more significant than that of incremental green technology innovation; In addition, the organization's redundant resources strengthen the positive correlation between radical green technology innovation and enterprise growth. This paper further classifies green technological innovation, further improves the theoretical framework of the relationship between green technological innovation and enterprise growth, enriches the research results in the field of technological innovation, and provides theoretical support for start-ups to better allocate green technological innovation resources.
