인터넷뱅킹과 은행 경영성과 = Internet Banking and Bank Performance: Evidence from an Internet Enthused Country

다국어 초록 (Multilingual Abstract)

First introduced in 1999, internet banking in Korea has grown in a surprising pace and emerged as the most important medium for banks' financial services. In 2005, 31.6% of services provided by banks was delivered by internet banking. Having observed the stellar growth of the internet banking, many commentators and practitioners asked a question on the profitability of internet banking services. Equipped with a very unique data set on internet banking services by Korean banks, we try to address the question. We believe that the evidence reported in the paper is the result of the first in-depth empirical investigation on the issue in Korea. First of all, we found that the increase in the share of banks' services delivered by internet banking did not contribute to higher return on equity in banking industry. We also found an evidence to support the claim that internet banking is beneficial to banks since it is much cheaper service providing channel than the traditional ones. We confirmed the negative relationship between expansion of internet banking and unit non-interest operating cost. Banks typically offer higher interest rate on deposit, better loan conditions and exemption of service fees to attract customers. Our conjecture is that the gain from cost reduction originated by expansion of internet banking is transferred to customers thanks to competition among banks.

국문 초록 (Abstract)

본 논문에서는 1999년 국내 은행산업의 새로운 서비스전달 채널의 하나로 등장한 이후 최근까지 빠르게 확산되고 있는 인터넷뱅킹이 은행의 수익성 향상에 기여하였는지 여부를 분석하였다. 더하여 인터넷뱅킹 확산이 비이자영업비용에 대한 영향을 점검함으로써 인터넷뱅킹의 비용절감효과 실현 여부를 확인하였다. 인터넷뱅킹의 확산이 국내 은행의 수익성에 의미 있는 변화를 결과하였다는 증거를 발견할 수는 없었으나 인터넷뱅킹의 확산에 따라 은행의 비이자영업부문의 단위비용이 낮아짐을 시사하는 증거를 확인할 수 있었다. 인터넷뱅킹의 확산이 이미 은행의 비용구조에 일정한 변화를 가져왔다는 발견에 근거하여 향후 시간이 경과하면서 인터넷뱅킹에 대한 투자의 효과가 본격적으로 나타남에 따라 궁극적으로는 인터넷 뱅킹의 확산이 은행의 수익성 증대로 귀결될 수 있을 것이라는 전망을 제시할 수 있다.
