摘 要:隨著公司治理機制的不斷完善,除股東利益最大化和控制風險保證商業銀行的穩定之外,對債權人利益以及全社會福利的保護也成為了商業銀行高管的任務之一。更多的任務目標條件導致激勵契約也更為復雜。在委托代理框架下,進一步分析商業銀行委托代理關系與高管所承擔的任務內容,基于此在Holmstrom-Milgrom模型框架下建立多任務商業銀行高管激勵契約并求出滿足最優解的條件。分析可得當我國監管部門和社會公眾無法提供最優激勵時,管理層會愈發追求績效來保證產出,進而減少在風險控制和承擔社會責任上的努力。長期來看,若管理層欲獲得最優激勵,就必須保證對社會責任的努力是穩定持續的。
關鍵詞:商業銀行治理;多任務委托代理;社會責任;激勵契約

Abstract:Because of the improvement of corporate governance, the protection of creditor and social welfare becomes one of the aims of the executives in commercial banks. More targets lead to the incentives more complex. In the principal-agent framework, analyze the principal-agent relations of commercial banks and the tasks executives taking, establish a multitasking principal-agent model based on the Holmstrom-Milgrom model, and then obtain the optimal conditions .The result indicates that when the supervisory department and social public are unable to achieve the optimal incentives, the administrators endeavors more to pursue profits instead of the risk control and social responsibility. In the long run, if the executives would like to obtain the optimal incentive, they have to keep a constant and stable endeavor on social responsibility.
Key words:corporate governance of commercia banks; multitasking principal-agent; corporate social responsibility; incentive contracts
1 引言公司治理理論中,委托代理理論始終占據重要地位。該理論的中心問題就是委托人如何提供最好的激勵契約使得代理人按照委托人的要求完成任務。可見,代理人應完成的任務目標是激勵契約履行的目的。與一般企業不同,商業銀行具有利益相關者眾多、經營目標較多、監管更為嚴格和信息透明度較差等特殊性,其委托代理關系與代理人應完成的任務亦更為復雜。隨著公司治理機制的不斷完善,除最大化股東利益和控制風險以保證商業銀行穩定經營之外,保護債權人利益以及全社會福利也成為了商業銀行高管的任務之一。……
