本研究之目的係探討臺灣銀行產業存款與放款市場借貸行為中之資訊不對稱現象。資訊不對稱現象是導致銀行產業存放款市場代理成本發生的主要原因之一,因此,如何有效降低銀行產業內資訊不對稱現象,進而降低代理成本並增進該產業競爭力是一個值得重視的課題。然而過去大部分的研究僅著重於銀行產業中存款或放款市場之單一方面資訊不對稱現象的探討,未嘗以系統性的觀點同時探討存在於銀行產業存款與放款市場之資訊不對稱現象,以及它們之間的互動關係。事實上,銀行產業之存放款市場間存在著連動關係,欲有效解決代理問題,必須從存款人、銀行與借款人之雙重代理關係的整體性觀點探討資訊不對稱現象。
為達本研究目的,本研究首先整合過去學者的論點,針對臺灣銀行產業存放款市場之資訊不對稱現象提出一個全面性與系統性之概念化分析模式,接著以本國之銀行產業為例,收集1999年至2006年,共計8年9,839筆之銀行存款與放款合約進行資訊不對稱現象之實證。根據資料分析結果顯示,國內銀行產業存放款市場之資訊不對稱現象確實存在著連動關係,且放款市場之放款利率及公司年齡變數會顯著影響存款市場之存款利率及銀行資產總額變數。此外,藉由集群與區別分析,本研究發現可將銀行存放款市場之資訊不對稱現象區分為三個集群,並依據各集群特徵分別命名為資深大規模群、低利貸中規模群及高存放利率群。三集群之意涵分別為:(1)資深大規模群:此一集群是大規模銀行與成立較久的公司的組合,屬於低風險群,即資訊不對稱程度較低;(2)低利貸中規模群:此一集群是中小規模銀行與放款利率較低借款公司的組合,屬於中度風險、中度資訊不對稱的集群;(3)高存放利率群:此一集群是高存款利率銀行與高放款利率借款公司的組合,屬於高度風險、高度資訊不對稱的集群。
This paper investigates the phenomenon of information asymmetry in the context of the savings and lending behavior in Taiwanese banking industry. The information asymmetry phenomenon is one of the important reasons that cause agency cost occurrence in the savings and lending activities in service banking. Therefore, it is a important issue in dropping the information asymmetry phenomenon of the banking industry, and reducing the agency cost to promote the industry competitiveness. Although information asymmetry has been previously studied in the context of savings and lending activities, such studies have only concentrated on either the bank–depositor relationship or the bank–borrower relationship. Few studies have undertaken research on the basis of a model which takes into account both of the bank’s bilateral asymmetrical relationships. In fact, there has a linkage relationship between savings and lending markets of the banking industry. If we want to resolve the agency problem effectively, we need to investage the information asymmetry phenomenon from a comprehensive view with dual-bilateral agency relationship among depositors, banks, and borrowers.
For the purpose of this research, the present study therefore integrated the standpoint of the scholars, and proposed a comprehensive and systematic analysis conceptual model, and then conducted an empirical study by totally 9,839 contracts from 1999 to 2006 of service banking in Taiwan. According to the data analysis, it is really existing the linkage relationship of the information asymmetry phenomenon in banking industry in Taiwan. The implications of these findings are further discussed in the paper.
