本文的目的是以台灣2000年至2009年台灣36家銀行的資料,分析股權結構對銀行績效的影響。模型設定主要參考Berger et al. (2005)所提的綜合各類銀行所有權型態之靜態、選擇與動態效果之聯合分析模型。實證結果發現: (一). 在靜態效果上,泛公股銀行的績效表現與民營銀行並無顯著差異。 (二). 在選擇效果上,經歷過併購的民營銀行績效表現比其他的銀行好;反之,被外資併購或參股的銀行,其績效表現都是比較差的。這表示有能力進行併購的民營銀行條件較佳;而政府允許外資進行併購或參股的銀行都是較差的銀行。 (三). 在動態效果上,國內民營銀行併購後績效表現短期會提升但隨著時間經過有逐漸惡化的趨勢;相反的,外資併購或參股後的銀行短期績效表現會惡化但隨著時間經過有逐漸改善的情形。
Using a panel of 36 Taiwanese banks over the 2000-2009 periods, we access the effects of bank ownership on performance. Our model refers to Berger et al. (2005), which conducted a joint analysis to examine the static, selection and dynamic effects of various ownership types or changes on bank performance. Our results indicate that: (1). pan-public banks have no significant difference on performance from private banks. (2). banks undergoing a domestic acquisition outperform those that don’t; in contrast, banks undergoing a foreign acquisition or invested by foreign equities record poor performance than those that don’t. This means banks which are capable of acquiring others perform better while banks which government permits foreign banks to acquire or foreign equities to invest in perform worse. (3). banks undergoing a domestic acquisition perform well in the short-run but deteriorate in the long-run; in contrast, banks undergoing a foreign acquisition or invested by foreign equities perform poor but get better in the long-run.
