フィリピン銀行部門再編が経営効率性に与える影響: マルムクィストdeaによるフィリピン銀行の経営効率性の計測とその決定要因


  • 齋藤, 純


本稿の目的は、まず、フィリピン銀行業の経営効率性を計測し、経営効率性の変化が銀行業全体の技術進歩によるものであるのか、銀行の規模経済性の変化によるものであるのか、または個別銀行独自の経営努力によるものであるのかを分析することである。さらに、その経営効率化もしくは経営非効率化が、銀行の健全性、成長性、収益安定性などの経営体質、また人件費や物件費、金利収入、手数料収入などの経営活動内容、そして、2000年代に頻発した銀行間の統合・合併など、どのような要因によるものかを分析することである。経営効率性の計測の結論を整理すると以下の通りである;第一に、2000年代のフィリピン銀行業の経営効率化は、一般的に改善している。第二に、銀行業全体の技術革新が認められる。第三に、規模の経済性が計測された。最後に、民間商業銀行と専業貯蓄銀行の純技術効率性は増加した一方で、政府系銀行、外国銀行、関連貯蓄銀行については低下した。生産性指数を被説明変数とした回帰分析の結果からは、以下のことが結論づけられる;第一に、銀行間の合併・統合は経営効率性の改善には繋がらなかった。第二に、金利収入は経営効率性に負の影響を与え、手数料収入は正の影響をを与えていた。, This paper measures efficiency of the Philippine banking sector in 2000s and investigates the component of efficiency change. Moreover, this paper analyzes the factors of the efficiency changes. The conclusion of the efficiency analysis of the Philippine banking by Malmquist DEA is as the following;. First, total efficiency index was improved in 2000s. Secondly, technical innovation was observed in the whole Philippine banking sector. Thirdly, scale effect was measured at the positive value. Finally, larg and middle Philippine banks didn't improve their pure technical efficiency. The regression analysis also showed that bank mergers do not improve bank efficiency in the Philippine.
