台灣農會信用部之成本結構、效率評估及相關改革政策之研究---使用隨機成本前緣法及資料包絡分析法

Abstract

本研究之目的在運用參數式隨機成本前緣法以及非參數式資料包絡分析法來評估 台灣農會信用部之成本結構與效率指標，進一步對規模經濟與範疇經濟之效果，以及影 響效率之原因均詳加探討，並尋求其政策上之意含，尤其農會信用部最重要之逾期放款 問題將列入放款品質之考量，而不同之效率衡量將用於績效之分析與比較。 農會信用部是台灣鄉下最重要之金融機構，但因金融體系與市場之自由化，造成商 業銀行之強力競爭與威脅，而部分農會信用部又因人謀不臧、控制鬆散，近年幾度造成 擠兌，讓政府憂慮會成為金融風暴的導火線。因此，農會信用部之經營效率需要進一步 之瞭解與掌握，本研究使用幾種不同之方法，考量農會信用部之特性，分析各種影響因 素之相互關係，期望能夠提供農會管理者在提昇經營效率，以及政府主管機關在研擬改 革方案時的參考。

The purpose of this research is to study the cost structures and efficiency measures of the Credit Departments of the Farmers』 Associations (CDFA) in Taiwan, adopting both stochastic cost frontier analysis and data envelopment analysis. Economies of scale and scope as well as the factors affecting efficiencies will be investigated, and the policy implications then explored. In particular, the loan output will be adjusted to account for quality problems faced by the CDFAs. Various efficiency measures will be used for performance comparison. The CDFAs are the most important financial institutions in rural Taiwan. Influenced by the deregulation and liberalization of the financial system, the CDFAs have encountered severe competition from commercial banks. Fraudulent practice, loose internal controls and lack of managerial efficiency have caused several cash-runs in recent years. A possible financial crisis has raised concerns about the soundness of the CDFAs. Hence, their operational efficiency needs to be investigated in details. Our study tries to explore this important issues of the CDFAs by multiple approaches considering the impact of non-performing loans, and further to elucidate the relationship between the affecting factors and efficiency measures. The results and the policy implications should be useful to managers of the CDFAs, to the financial institutions that might acquire CDFAs, and the policy-makers in the government.
