Abstract

As South Korean large business groups, also known as Chaebol, have broadened their influence in the domestic economy, it is important to analyze the influence of internal transactions among Chaebol affiliates on their performance. In this paper, relationship between internal transactions and efficiency of Chaebol affiliates has been analyzed. Top five Chaebol groups in South Korea are selected; they include Samsung, Hyundai Motors, LG, SK, and Lotte group. Based on internal transactions among affiliates, social networks are constructed for each Chaebol group to analyze centrality, network structures and cliques. Data Envelopment Analysis (DEA) was conducted to examine the efficiency of the Chaebol affiliates. Then, correlations between the degree centrality and the efficiency of Chaebol affiliates were analyzed, and the network structures of Chaebol groups are presented. The result shows that positive correlations between degree centrality and efficiency are observed among four Chaebol Groups. This paper shows that the Social Network Analysis (SNA) techniques can be used in the empirical research for the analysis of internal transactions of Chaebol groups.
基于社会网络分析的财阀子公司内部交易与效率的相关性分析
随着韩国大型企业集团(财阀)在国内经济中的影响力不断扩大,分析财阀子公司之间的内部交易对企业业绩的影响非常重要。本文分析了财阀子公司内部交易与效率的关系。选出韩国五大财阀集团;包括三星、现代汽车、LG、SK、乐天等。以子公司之间的内部交易为基础,构建各财团的社会网络,分析中心性、网络结构、派系。通过数据包络分析(DEA)分析了财阀子公司的效率。在此基础上,分析了财阀集团关联方的中心性与效率之间的相关关系,并给出了财阀集团的网络结构。结果表明,四个财阀集团的度中心性与效率之间存在正相关关系。本文表明,社会网络分析(SNA)技术可以用于财阀集团内部交易分析的实证研究。
