“…Moreover, patents' metadata, e.g. who invented what and when, can provide the basis for social network analysis to visualise and streamline the interpretation of social dynamics (Meyer 2002, Binz et al 2014, Liu et al 2022. The underlying assumption of knowledge transfer is that through collaborative innovation activity, social interactions facilitate the flow of (implicit) knowledge (see (Howells 1996, Breschi and Lissoni 2009, Dima and Vasilache 2015 for more information).…”

Radical innovations can shift the global competitiveness of entire nations. While countries typically struggle to absorb knowledge about novel technologies quickly, in which knowledge tends to be spatially sticky, an important exception is the fast catch-up of the Korean Li-ion battery (LIB) industry from Japan in the early 2000s. In this paper, we conduct an exploratory case study on this surprising success story. Focussing on patent co-inventions between Korea and Japan, we investigate their significance, as well as underlying types of co-inventions and types of transferred knowledge. To this end, we proceed in four steps: 1) a Poisson regression model; 2) social network analyses; 3) patent inventor tracking and 4) patent coding. Our results indicate that Korean-Japanese co-inventions hold significantly greater influence than other cross-country co-inventions, including with patents without cross-country collaboration. We find a pronounced knowledge-transfer intensity during the early 2000s and observe two types of co-inventions: organisation-level and inventor-level. Predominantly, we observe inventor-level co-inventions, i.e., Korean companies hiring experienced Japanese engineers, that proved important to transferring sticky knowledge. Moreover, while most patents target the design of core battery components, the share of manufacturing patents are – contrary to theoretical expectations – highest during the first half of the observation period. We also discuss our findings and draw implications for policy, industrial and academic players, including industry localisation policies, technology-inherent catch-up strategies and directions for future research.

“…In the future work, we will further extend the research perspective to the global NEV industry, including special samples such as multinational companies and joint ventures in the research framework of the article. At the same time, based on the perspective of knowledge spillover and knowledge flow, this study will deepen the research and enlightenment on the development of the global NEV industry [26]. On the other hand, the data sources are expanded.…”

“…This study finally obtained 9852 joint patent application data in the field of NEV. The essence is an interactive and innovative process in which organizations are embedded in social networks and carry out knowledge flow and resource integration [26]. It can reflect the sharing and transfer of knowledge across organizations.…”

Under the dual pressure of energy transformation and environmental protection, how to use the innovative network and enhance technical innovation (TI) are significant problems for new energy vehicle (NEV) enterprises in China. Based on the patent data of China’s NEV industry from 2001 to 2022, combined with the logical framework of “Patent Analysis—Network Evolution—Empirical research”, this study deeply discusses the influence of enterprises’ innovative network on TI. It is shown that there is an inverse U-relationship between the cooperation breadth of the enterprises, and that the appropriate cooperation breadth favors TI. At the same time, structural holes, knowledge diversity and technical value have a significant positive impact on TI. In addition, the study performs a series of robustness tests and heterogeneity checks. The conclusions are conducive to further improving the study of the relationship between innovative networks and TI, which is important both theoretically and practically for promoting the energy transformation of automotive enterprises.

“…However, the ultimate goal of technological inventions is commercialization, that is, bringing the invention to market (Walsh et al, 2016). Paper collaboration is an active and mutual process involving financial and knowledge exchange, but not a purely transactional act (Zhang et al, 2016), and patent citations reflect more the technical value than the economic value of the patent (Liu et al, 2022). The patent transfer is regarded as the core process of technology commercialization (Choi et al, 2015).…”

Does external linkage stimulate innovation capacity? The analysis based on “dual‐pipelines” framework

Drawing on "buzz-and-pipeline" theory, we develop a framework termed "dual-pipelines" to discover how the local innovation capacity can benefit from transnational and domestic introduced technology. We find that the intensity of transnational and domestic patent introduction both have an inverted U-shaped relationship with local innovation capacity. Also, the relatedness and similarity of domestic technology introduced are advantageous to local innovation. However, the transnational introduced technologies are only beneficial if they perform similarly to the local knowledge base while having no significant effect if merely showing relatedness. Finally, transnational and domestic technology introductions complement each other in promoting local innovation capacity.
