Abstract:Micro-innovation is an important way for specialized new enterprises to solve the "stuck" problem and achieve technological leaps. The development of specialized, special and new enterprises is currently a hot topic in academic research, but the current understanding of the driving factors and stages of specialized, special and new micro-innovations is not yet deep enough. This study collected relevant secondary data from corporate annual reports, corporate websites and academic journals, used Python for text mining and patent citation network analysis to identify specialized, new and micro-innovative enterprises with a high degree of digital transformation, and used grounded theory coding technology for data processing. , study and construct a dynamic mechanism model of micro-innovation in specialized and special new enterprises, and take two typical enterprises as examples to use case analysis method to study the different stages of micro-innovation and the influencing factors and interactions between influencing factors at each stage. . Research shows that (1) industry environment and partners are external guiding factors, knowledge ecology and organizational capabilities are internal driving factors, and digital infrastructure and digital economy are reinforcing factors; (2) Micro-innovation is divided into micro-innovation opportunity identification and There are three stages: framing, continuous trial and error and rapid iteration, and a round of micro-innovation implementation. In the continuous trial and error and rapid iteration stage, the enterprise"s knowledge ecology and organizational capabilities interact with each other. The industry environment and partners are the external factors of micro-innovation. Orientation, digital infrastructure and digital economy provide digital empowerment for micro-innovation. Based on this, it is proposed to focus on the construction of enterprise knowledge ecology and the cultivation of organizational capabilities, constantly adapt to the external environment and strengthen the connection between partners, develop the enterprise"s digital infrastructure, and the government promote the development of the enterprise"s external digital economy.
