Abstract: This study measures the technological distance between firms within and across industries as a case study of Chinese firms to investigate firms’ technology accumulation patterns. Specifically, cosine similarity is used to compare the t echnology positions generated by the patent applications of Chinese firms. The analysis shows that as the number of patent applications increases, firms tend to deepen the technological characteristics of each industry and firm while broadening t he variety of technological fields. As a result, although the quantity and quality of t echnologies are critical, understanding the characteristics of technologies as a t echnological structure or system that differs from one firm to another is also crucial.
