“…Network analysis is a method used to quantitatively analyze the relationship of individualized nodes, and is also a technique to identify the regular and stylized patterns that are consequently induced by interactions between actors [ 28 ]. Network analysis can find various hidden relationship types that are not normally recognized, and can structurally grasp the expression of specific relationship types [ 29 , 30 ].…”

Background As the need for digital health care based on mobile devices is increasing, with the rapid development of digital technologies, especially in the face of the COVID-19 pandemic, gaining a better understanding of the industrial structure is needed to activate the use of digital health care. Objective The aim of this study was to suggest measures to revitalize the digital health care industry by deriving the stakeholders and major issues with respect to the ecosystem of the industry. Methods A total of 1822 newspaper articles were collected using Big Kings, a big data system for news, for a limited period from 2016 to August 2021, when the mobile health care project was promoted in Korea centered on public health centers. The R and NetMiner programs were used for network analysis. Results The Korean government and the Ministry of Health and Welfare showed the highest centrality and appeared as major stakeholders, and their common major issues were “reviewing the introduction of telemedicine,” “concerns about bankruptcy of local clinics,” and “building an integrated platform for precision medicine.” In addition, the major stakeholders of medical institutions and companies were Seoul National University Hospital, Kangbuk Samsung Hospital, Ajou University Hospital, Samsung, and Vuno Inc. Conclusions This analysis confirmed that the issues related to digital health care are largely composed of telemedicine, data, and health care business. For digital health care to develop as a national innovative growth engine and to be institutionalized, the development of a digital health care fee model that can improve the regulatory system and the cost-effectiveness of patient care, centering on the Ministry of Health and Welfare as a key stakeholder, is essential.

“…Indeed, the combination of innovation and spatial networks has allowed researchers to apply methods traditionally used in Social Network Analysis (SNA) [ 3 ]. For example, [ 6 ] explore comparative advantages and driving forces of technological innovation in China’s rare earth industry with the help of SNA methods. While [ 4 ] use SNA to investigate specifically how innovation is propagated through a network in the agricultural sector and which actors occupy positions of importance when it comes to sharing information.…”

“…One promising approach has proved to be analyzing innovation through the lens of geospatial company networks. In particular, this allows scientists to employ traditional Social Network Analysis methods ( SNA ) [ 3 ] which enable a more detailed analysis of innovation in company networks [ 4 – 6 ]. While some authors also specifically examine geospatial connection strategies of companies associated with more innovative behavior e.g.…”

Innovation in hyperlink and social media networks: Comparing connection strategies of innovative companies in hyperlink and social media networks

This paper seeks to unveil how (geospatial) connection strategies associated with business innovation, differ between geolocated social media and hyperlink company networks. Thereby, we provide a first step towards understanding connection strategies of innovative companies on social media platforms. For this purpose, we build a hyperlink and Twitter follower network for 11,892 companies in the information technology (IT) sector and compare them along four dimensions. First, underlying network structures were assessed. Second, we asserted information flow patterns between companies with the help of centrality measures. Third, geographic and cognitive proximities of companies were compared. Fourth, the influence of company characteristics was examined through linear and logistic regression models. This comparison revealed, that on a general level the basic connection patterns of the hyperlink and Twitter network differ. Nevertheless, the geospatial dimension (geographic proximity) and the knowledge base of a company (cognitive proximity) appear to have a similar influence on the decision to connect with other companies on Twitter and via hyperlinks. Further, the results suggest that innovative companies most likely align their connection strategies across hyperlink and Twitter networks. Thus, business innovation might effect connection strategies across online company networks in a comparable manner.

“…There is a lack of research on the security of the whole supply chain of “exploration, mining, beneficiation, separation, metallurgy and recovery” and even the security issues posed by the technology property rights barriers attached. Take the patents of the whole rare earth industry as an example, China’s patent advantage is concentrated in the middle-end of the chain, while Japan, the USA, Korea, and the EU hold the patent advantages in the upstream and downstream of the supply chain (Leng et al 2021 ). However, the risks posed by such industry-wide technical barriers are not reflected in the traditional safety evaluation system for critical minerals.…”

Critical minerals are the cornerstone of the new round of the industrial revolution. The global division of labor established under the traditional technology, industry, and trade systems is facing a significant restructuring. Global economic and technological changes will lead to a long-term increase in demand for critical minerals. The critical minerals supply chain is rife with political interference and distorted trade practices compared to the robust resource demand. It faces several challenges that threaten the sustainability of the supply chain. We analyze the evolving security connotation of critical minerals supply chains. We also provide an overview of research on quantifying risks of critical minerals from two aspects: security evaluation mechanism and global value chain. The interdisciplinary research techniques and methods are more adapted to the new trends of international competition in critical minerals. The article reviews relevant security risk identification and response research in critical minerals supply chains. It analyzes how to address the risk challenges from national strategies. Finally, the article explores new trends under new technological revolution and industrial change.
