ABSTRACT

Recent materials play a significant role in the acquisition of technological innovation capacity for new products, and with technological complexity gradually increasing, it is necessary to integrate technological knowledge such as technology convergence to interpret technological innovation. In this context, accurately understanding technology convergence of materials and predicting promising technology convergence is essential to securing continued national and corporate competitiveness. Therefore, this study investigated technology convergence in the material field focused on automotive lightweight materials. The data were extracted from the Korean Intellectual Property Office, to which the methodologies of technology convergence ratio, similarity measures, and network analysis were applied. Our findings are as follows: (1) the proportion of patents containing technology convergence increases over time, and the convergence between technology fields in mechanical engineering is more active than between technology fields in chemistry; (2) convergence between a few core technologies within the network is weakening, and a new and strengthening pattern of technology convergence can be confirmed; (3) the network is more complex and the convergence of different areas of technology is increasing. These results enable an accurate understanding of the present and future of technology convergence and support government initiatives.

摘要

新材料对新产品技术创新能力的获得具有重要作用，随着技术复杂度的逐渐增加，需要结合技术融合等技术知识来解读技术创新。在这种情况下，准确理解材料的技术融合并预测有前途的技术融合对于确保持续的国家和企业竞争力至关重要。因此，本研究调查了以汽车轻量化材料为重点的材料领域的技术融合。数据来自韩国知识产权局，应用了技术融合率、相似性度量和网络分析的方法。我们的调查结果如下：(1) 包含技术融合的专利比例随时间增加，机械工程技术领域之间的融合比化学领域技术领域之间的融合更为活跃；(2) 网络内少数核心技术之间的融合减弱，可以确认新的技术融合强化格局；(3) 网络更加复杂，不同领域技术的融合越来越多。这些结果有助于准确了解技术融合的现在和未来，并支持政府的举措。(2) 网络内少数核心技术之间的融合减弱，可以确认新的技术融合强化格局；(3) 网络更加复杂，不同领域技术的融合越来越多。这些结果有助于准确了解技术融合的现在和未来，并支持政府的举措。(2) 网络内少数核心技术之间的融合减弱，可以确认新的技术融合强化格局；(3) 网络更加复杂，不同领域技术的融合越来越多。这些结果有助于准确了解技术融合的现在和未来，并支持政府的举措。
