This study focuses on (1) the relationship between the network intensity of top managers and the R&D investment of Korean firms, and (2) the moderating effects of the type (related-division vs. unrelated-division) and system (physical division vs. spin-offs) of corporate division on this relationship. The sample of this study was all type and/or system of corporate division implemented by Korean firms during 18-years (1999-2016) study periods. The results of multiple regression analyses as follow. First, as was expected in hypothesis 1 the network intensity of top managers has a strong positive linear relation with the R&D investment of Korean firms. Second, regarding the moderating effect of division type the results show that related-divisions significantly intensify the positive relationship of the network intensity of top managers with the R&D of Korean firms although unrelated-divisions did not. Third, in the analysis of moderating effect of corporate division system the results present the stronger positive moderating effect of spin-offs rather than physical divisions. The findings of the study implies that strong network intensity of top managers can be beneficial to long-term decision such as R&D investment of Korean firms. They accords to network theory that emphasize the importance of strong network effect among top managers based on their trust. The findings also implies that researchers and practitioners should consider organizational-level factors such as organizational structure, culture, corporate governance, etc as well as individual-level factors such as the characteristics and relationships of organizational members when making the decision for firm.

According to the rise of the 4th Industrial Revolution, the need for innovation networks through cooperation between participants is increasing to respond to rapidly changing technologies and corporate environments. Especially, cooperation is essential to solve and innovate problems faced SMEs lacking human and material resources. We conducted a study to revitalize the regional cooperation network by analyzing the current status and problems of the existing SME support network. As a result, We derived a strategy to create a foundation for a regional cooperation network through reorganization of existing cooperation networks, the establishment of customized policies for SMEs, and linkage of support projects. And we derived a strategy for establishing a specialized network for regional innovation as a result of research through Establishing a network for regional bases, strategies for fostering companies by growth stage, and utilizing local data. We expect that it will help establish a policy to support SMEs by preparing an organic cooperation system between local businesses and local networks.

China has gone through rapid economic growth due to transitional economies since 1978. In particular, Chinese transitional economies has led to fundamental changes in firms' activities under the socialist system. Nevertheless, Chinese firms have formed new industrial production organizations and spatial orders by sustaining personal networks based on existing traditional firm practice, which is called 'guanxi'. Therefore, the main purpose of this research is to identify the influence of personal networks, guanxi, on the business activities of Chinese firms by investigating the formation of guanxi mechanism. The main characteristics of guanxi represented in inter-firm relations are as follows. First, guanxi has played a role in facilitating inter-firm relations and business activities, because it has an inter-debt relations based on inter-reciprocal relations between firms. Second, Chinese firms has depended on posteriori guanxi rather than inherent guanxi by the internalization of personal networks through 'guanxi communicators'.Third, guanxi between firms and local government in extra-firm relations has been established to minimize risks from unstable legal regulations.

In July 2021, UNCTAD classified Korea as a developed country. After the Korean War in the 1950s, economic development was promoted despite difficult conditions, resulting in epoch-making national growth. However, in order to respond to the rapidly changing global economy, it is necessary to continuously study the domestic industrial ecosystem and prepare strategies for continuous change and growth. This study analyzed the industrial ecosystem of the automobile industry where it is possible to obtain transaction data between companies by applying complexity spatial network analysis. For data, 295 corporate data(node data) and 607 transaction data (link data) were used. As a result of checking the spatial distribution by geocoding the address of the company, the automobile industry-related companies were concentrated in the Seoul metropolitan area and the Southeastern(Dongnam) region. The node importance was measured through degree centrality, betweenness centrality, closeness centrality, and eigenvector centrality, and the network structure was confirmed by identifying density, distance, community detection, and assortativity and disassortivity. As a result, among the automakers, Hyundai Motor, Kia Motors, and GM Korea were included in the top 15 in 4 indicators of node centrality. In terms of company location, companies located in the Seoul metropolitan area were included in the top 15. In terms of company size, most of the large companies with more than 1,000 employees were included in the top 15 for degree centrality and betweenness centrality. Regarding closeness centrality and eigenvector centrality, most of the companies with 500 or less employees were included in the top 15, except for automakers. In the structure of the network, the density was 0.01390522 and the average distance was 3.422481. As a result of community detection using the fast greedy algorithm, 11 communities were finally derived.

In this paper, we study the recent changes in the credit risk interconnectedness in Korea. Using the CDS spread data from November 2015 to August 2022, we estimate the network structure of sovereign and corporate credit risk. The results show that sovereign and corporate credit risks are interconnected significantly, particularly with respect to the banking sector where FX-related transactions are made. Since 2022 when the monetary policy has become contractionary, such credit risk interconnectedness seems to be strengthened because of greater common exposure.

The purpose of this study is to identify the role of T-shaped skill between customer/supplier network and innovation performance of firms. To manage effectively the relationship between collaborative firms, firms need to have a prior related knowledge. The premise of absorptive capacity is that the organization needs prior related knowledge to recognize, assimilate, and apply new knowledge. In this context, T-shaped skill facilitates the learning of new related knowledge. The skill is thus a critical component of innovative capabilities. We found that T-shaped skill plays a mediating role in the relationship between networks and innovation performance. The conclusions and implications are discussed.

오늘날의 기업들은 글로벌 갱쟁환경과 고객 기대수준의 상승 등의 이유로 글로벌 소싱 및 기업간 전략적 제휴나 협업 등에 많은 관심을 기울이고 있다. 공급사슬관리(Supply Chain Management: SCM)는 기업과 기업, 기업과 고객 사이의 물류와 정보로 이어진 네트워크를 가능하게 실현할 수 있는 혁신기법이다. 본 논문에서는 공급사슬구조를 하나의 네트워크로 파악하여 공급네트워크, 전환네트워크, 유통네트워크라는 유형으로 구분하였고, 공급사슬구조에 따라 SCM 활동에 차이가 있으며, 경영성과에도 차이가 있음을 입증하였다. 따라서 본 논문은 현재까지 사례연구로 행해지던 네트워크의 분류를 이용하여 각 공급사슬구조에 따른 SCM의 활동 및 경영성과에는 차이가 있음 실증분석을 통하여 입증하였다는데 의의가 있다.

This paper aims to explore the characteristics of regional network of Korean firms in Dalian City, China, which is focused on social, cultural and institutional characteristics. To achieve this goal, the paper attempts to analyze the supply of raw material and parts, sales and cooperative relations of the firms. Among Korean firms in Dalian City, the characteristic of non-local network can be seen in supply enterprise of raw material, parts and semi products. On the other hand, a tighter local network relationship can be seen in sales. Large companies appear stronger in non-local network than small businesses and small businesses are stronger in local network. In terms of cooperation among enterprises, many firms have networks of joint marketing, joint use of equipments, exchange of techniques and information with the supply enterprise. With the customer enterprise, there is a network in joint marketing and manpower training. Especially, most of the customer enterprises are Chinese ones, which have extensive networks in big cities, such as in Beijing, Shanghai, Guangzhou, Tianjin and Dalian. In local network, the Korean firms in Dalian cooperate in product development, finance and manpower training with local firms. And in non-local cooperation, Korean firms are active in tech support, information exchange and R&D.
