Abstract

Technological innovation has become the main driving force for economic and social development, and also the focus of competition between countries or enterprises. This paper uses the propensity score matching method (PSM) in causal reasoning to study and analyze the impact of cross domain fusion of patent knowledge and technology on changes in patent value. Specifically, this paper selects patent data from the "Chemistry and Metallurgy" field of the China Intellectual Property Office from 2011 to 2020, and analyzes the frequency of patent citation as a substitute variable for the value of patent technology. The experimental results indicate that cross domain fusion of patent technology has a significant positive effect on improving patent value and is a related factor in increasing the frequency of patent citations; And the processing effect of multi domain fusion is significantly better than that of dual domain fusion. Therefore, cross domain integration of technology can increase the frequency of patent citations and ultimately enhance patent value. Our research can capture the causal relationship between the cross domain phenomenon of patent technology and the frequency of patent citations, and provide corresponding suggestions for promoting knowledge innovation.
