低利率環境下銀行業獲利能力成長之影響因素探討
The Factors that Influence the Profitability Growth of the Banks when Interest Rate is Low
摘要
金融危機發生後，全球銀行業共同面臨低利率環境壓縮了獲利能力。本研究以ROA及ROE為銀行業獲利能力的指標，探討了銀行業在2010到2016年低利率期間的成長趨勢以及影響其成長趨勢的因素，亦發現銀行業為維持獲利能力所做的改變。其中，ROA是銀行業較為關注的指標，因為銀行的負債比例較高，ROA可以看出銀行不依靠槓桿的經營能力。本研究發現以ROE而言，獲利能力確實有逐年遞減的趨勢，而ROA則不明顯。另外，股東權益比例正向調節了ROE的成長趨勢，擁有較高股東權益比例的銀行，較能緩解ROE逐年遞減的趨勢。貸款比例及貸款損失準備率則負向調節ROA的成長趨勢。而以上三項比例皆與銀行業所面臨的各種風險有關，本研究亦發現銀行業在研究期間可能會調整其可能面臨的風險，緩解ROA隨時間遞減的趨勢。

After the financial crisis, the global banking industry faced a low interest rate period and compressed profitability. This study uses ROA and ROE as indicators of the profitability of the banking industry. It explores the growth trajectory of the banking industry during the low interest rate period from 2010 to 2016 and the factors affecting its growth trajectory. It is also found that the banking industry has done change. Among them, ROA is an indicator that the banking industry pays more attention to, because the bank's debt ratio is relatively high, ROA can see that the bank does not rely on the operating capacity of leverage. This study found that in terms of ROE, the profitability does indeed decrease year by year, while ROA is not significant. In addition, the equity ratio has positively adjusted the growth trajectory of ROE. Banks with a higher equity ratio can better alleviate the decreasing trend of ROE year by year. The loan ratio and loan loss provision negatively moderated the growth trajectory of ROA. The above three ratios are all related to the various risks faced by the banks. This study also found that banks may adjust the risks it may face during the study period to alleviate the decreasing trajectory of ROA over time.
