IFSB(Islamic Financial Services Board)의 보고에 따르면 이슬람금융은 은행산업을 중심으로 지난 2000년 이후부터 국제유가의 상승과 더불어 연평균 20%에달하는 높은 성장율을 보여왔다. 글로벌 금융위기의 시작을 알린 2007~2008년도의 경우, GCC국가(바흐레인, 쿠웨이트, 오만, 카타르, 사우디아라비아, 아랍에미리트 등 총 6개국) 내 일반은행은 자본기준 16.3%, 수익기준 -6.1%의 성장율을 보인 반면, 이슬람은행은 38.2%의 자본성장율과 20.1%의 수익성장율을기록하면서 일반은행에 비해 높은 성과를 달성하였다(IFSB 2010).또한Bankscope 자료를 바탕으로 총자산 기준 세계 1000대 은행을 산출한 결과 이슬람은행은 1996년도에는 5개에 불과했으나 2010년도에는 12개로 증가하였음을알 수 있었다.1) 이러한 성장세와 더불어 최근 이슬람은행에 대한 관심이 높아지고 있는 가운데 이에 대한 학문적 연구가 상당히 진척되고 있다. 하지만 그 역사가 짧고외부에 노출된 것도 오래되지 않아 이슬람은행에 대한 선행연구는 주로 구조와특징을 소개하고 기존의 일반은행과 비교함으로써 차이점을 서술하는 소위 ‘개념적 연구’가 주를 이루었다(Archer, et al. 1998; Beck, et al. 2010; Grais & Pellegrini 2006b; Grais & Pellegrini 2006c). 또한 이슬람은행에 대한 실증연구는일천한 가운데 효율성 및 안정성(Cihak & Hesse 2008, 2008; Yudistira 2004), 또는 수익성(Zeitun 2012; Samad 2004)과 같은 재무 분석이나, 이익조정 문제를 탐색(Quttainah, et al. 2011)하는 정도에 그치고 있다. 한편 이슬람은행의 기업지배구조에 관한 연구 역시 다른 연구주제에 비해부족한 상태이며, 그나마 진행된 연구도 기존 제조업을 대상으로 한 지배구조연구의 지식재생산에 가까운 정도이다. 경영연구의 주요 이슈 중 하나인 기업지배구조의 관점에서 진행된 이슬람은행 연구는 지배구조의 역할 및 구조적 특성을 중심으로 일부 진행되었다. 이들 연구는 주로 이슬람경제(Islamic Ecnomics)라는 사회적 측면과 이슬람의 율법에 부합해야 하는 종교적, 윤리적측면을 중심으로 지배구조의 문제를 다루거나(Abdel Karim 2001; Haqqi 1999; Lewis 2005; Saeed 1996), 전통적인 지배구조 연구 경로를 따라 향후 지속적인사업성장을 위해 개선이 필요하다는 내용이 주를 이루고 있다(Abdussalam 2009; Chapra 1992; Chapra & Ahmed 2002). 이로써 이슬람은행의 지배구조가 기업가치에 미치는 영향에 대한 우리의 실증적 이해는 불균형 상태이며, 특히 투자결정 및 은행의 경영감독 등 주요 활동부문에 영향력을 행사함으로써 이슬람은행의 재무성과를 결정할 것으로 기대되는 샤리아위원회(Sharia Committee)에 대한 실증분석은 더더욱 일천하다. 이는 근본적으로 샤리아위원회에 대한 정보수집과 시계열 자료구축이 어렵기 때문인데, 이에 대한 실증연구를 위해 본 연구자들은 샤리아위원회 정보를 수집하여 기초 데이터를 구축하였다. 궁극적으로 이 글은 개념적 선행연구에서 한발 더 나아가 GCC 국가 내 48개일반 상업은행과 27개 이슬람은행에 대한 실증분석을 통해 다음과 같은 두 가지 목적을 추구한다: (1)일반은행과는 다른 이슬람은행의 지배구조가 지닌 특성과 은행의 기업가치 간 상관관계를 살펴보고, (2)샤리아위원회의 규모 및 외부감독기관의 구성원 비중이 이슬람은행의 기업가치에 미치는 영향을 확인하고자 한다. 이로써 이 글은 일반은행과 이슬람은행을 대상으로 은행의 지배구조와 기업가치 간 관계에 대한 이해의 폭을 넓히고, 이슬람은행 지배구조의 독특한 구성체인 샤리아위원회와 기업가치 간 관계에 대한 새로운 이해를 도모한다는 데 그 의의를 지닌다.
Abstract
This paper aims to explore the relationship between corporate governance and firm value of Islamic banks in countries of the Gulf Cooperation Council (GCC), and to investigate the direct effect of the scale of the Sharia Supervisory Board on the firm value. 38 conventional commercial banks and 27 Islamic banks are explored. The period of research lasted from 2003 to 2007. To conduct a comparative analysis on the 65 banks based on the panel data, the Hausman-Taylor analytical model was used. The findings of the analysis predominantly concerns: 1) the absence of a significant relationship between corporate governance and firm value for both Islamic and conventional banks in GCC countries, 2) the absence of a significant relationship between the scale of the Sharia Supervisory Board, which manages and monitors Islamic banks, and bank firm value.
