Assessing advancements of technology is essential for creating science and technology policies and making informed investments in the technology market. However, current methods primarily focus on the characteristics of the technologies themselves, making it difficult to accurately assess technologies across various fields and generations. To address this challenge, we propose a novel approach that uses bibliometrics, specifically literature citation networks, to measure changes in knowledge flow throughout the evolution of technology. This method can identify diverse trends in technology development and is an effective tool for evaluating technological advancements. We demonstrate its accuracy and applicability by applying it to mobile communication technology and comparing its quantitative results with other assessment methods. Our work provides critical support for assessing different technical routes and formulating technology policy.
