초록

본 연구의 목적은 자동차산업에서 실제 거래 데이터를 활용하여 구매업체-공급업체 간 거래관계(링크)에 연결강도를 반영하였을 때 특정기업(노드)의 중심성이 어떻게 달라지는지 사회연결망 분석을 통해 살펴보는 것이다. 이를 위해 중국에 진출한 글로벌 완성차업체의 여덟 개 현지 합작법인(상하이폭스바겐, 일기폭스바겐, 광주도요타, 광주혼다, 상하이지엠, 장안 포드, 북경현대, 동풍열달기아)과 다양한 공급업체들을 대상으로 연구를 진행하였다. 보다 구체적으로 세 개 품목(에어백, 인테리어, 시트)별로 거래관계 네트워크와 연결강도 네트워크를 비교하여 연결중심성과 위세중심성이 어떻게 변화하는지, 그리고 품목별 특성에 따라 네트워크 구조가 어떻게 달라지는지 살펴보았다. 그 결과 공급네트워크에 관계 속성인 연결강도를 추가하는 경우 모든 품목에서 공통적으로 연결중심성이나 위세중심성 값이 더 커지는 것으로 나타났으며, 모든 연결강도 네트워크에서 한국계 완성차업체가 자사 공급업체들과 상대적으로 더욱 강한 연결을 구축하고 있음을 확인하였다.

Abstract

This study aims to examine how the centrality of a specific node (firm) changes when tie strength is reflected in a link (buyer - supplier relationship). By using actual transaction data, we researched eight global automakers (SAIC Volkswagen, FAW Volkswagen, GAC Toyota, Guangqi Honda, SAIC GM, Changan Ford, Beijing Hyundai, and Dongfeng Yueda Kia) and various suppliers who have entered China and supplied them with several items. All of eight automakers are joint ventures with global carmakers and Chinese state-owned enterprises

We have examined how the degree centrality and eigenvector centrality change in transaction network and tie strength network of the airbag, interior, and seat-related product categories. As a result, adding the tie strength to the transaction relationship would increase the value of degree centrality or eigenvector centrality in all product categories in common. This is quite different from existing research that only considered transaction networks. It also confirmed that Korean carmakers have strong ties with their suppliers in all tie strength networks. The reason for this is that Korean suppliers have been in business for a long time with customers in Korea.

This study has significant meaning in terms of understanding the dynamics and network structure of the actual supply network of automobile industry considering the tie strength, but there are limitations due to the data. First, we measured the tie strength with the number of product items because we were unable to figure out the sales between buyer and supplier. Second, we could not grasp the tier of the supplier and the transaction relation between suppliers in the data. Therefore, improving these limitations in future studies will allow us to analyze supply networks closer to reality.
