銀行業被認為是提升企業社會責任(corporate social responsibility, CSR)的關鍵行為者,因為它們有能力通過其產品和服務影響其客戶和其他公司,而且相對於其它行業別是表現較差者。本研究在藉由常用的多準則決策分析(multi-criteria decision analysis, MCDA)方法來評估台灣銀行業的企業社會責任績效。 本研究選擇Preference Ranking Organization Methods for Enrichment Evaluations (PROMETHEE II) 以及 Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) 兩方法進行分析。蒐集15家台灣銀行與其它歐美一些頂級銀行的環境、社會和公司治理(environmental, social and corporate governance, ESG)資料為分析對象。 分析結果顯示,此15家銀行在 TOPSIS和PROMETHEE II 兩方法的評估結果排序相近,並且這在銀行排名差異不明顯。對於主要準則權重變化的敏感度分析,並沒有產生顯著不同的排序,因而推斷這些排名是穩定的。根據以上MCDA方法分析結果,我們可以得出結論:台灣銀行的企業社會責任表現明顯低於資料中歐美頂級銀行的表現,因而這些表現優良銀行多個面向的指標可以作為台灣銀行績效改善的參考。
The banking industry is considered as a key actor to enhance corporate social responsibility (CSR) since they have the ability to influence their customers and other companies through their products and services, and achieve relatively poor performance compared to other industries. This study aims to evaluate CSR performance of the banking industry in Taiwan through multi-criteria decision analysis (MCDA) methods. Preference Ranking Organization Methods for Enrichment Evaluations (PROMETHEE II) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methods were selected to perform the analysis. The environmental, social and corporate governance (ESG) data of fifteen banks in Taiwan and some top-performed banks from different continents is collected and analyzed. Findings show that both, TOPSIS and PROMETHEE II, generate close rankings and ranking differences, among the banks by the two methods, are considered as insignificant. Sensitivity analyses on weight changes of major criterion do not provide significantly different rankings which are regarded as stable rankings. Based on the rankings obtained from above MCDA methods, we can also conclude that Taiwan-based banks have a significantly lower CSR performance than the top-performed banks from our dataset. We consider that using top CSR performing banks as a guidance to implement better CSR initiatives could help as a starting point to find improvement opportunities for the Taiwanese banks, especially in the lowest performing CSR criteria like resource management and board activities and its functions.
