Abstract:Digital innovation has a profound impact on the efficiency of digital economy construction and is of great strategic significance for China to build a competitive advantage in the digital era. Based on the Statistical Classification of Digital Economy and Its Core Industries by the National Bureau of Statistics and the Reference Table between International Patent Classification and National Economy Industry Classification by the Intellectual Property Office, this article uses patent data to identify digital innovation at the level of IPC main groups, and analyzes the current situation of digital innovation in China from three aspects: quantitative characteristics, technical characteristics, and quality characteristics. It is found that there is a single type of innovation subject in current digital innovation in China Problems such as concentrated technological scope and imbalanced development between regions. We propose that policies should be formulated to promote the participation of diverse entities in digital innovation, improve the efficiency of related patents, enhance the diversification of digital innovation technology paths, promote the balanced development of digital innovation between regions, encourage exploratory digital innovation, and enhance its fault tolerance mechanism.
