本研究目的於探討總體經濟狀況和銀行體質特徵不同與銀行貸款行為之間的關聯性。本研究以2010至2023年6月共54個季度，與規模前30大之銀行特徵為樣本，並加入總體經濟之變數透過OLS方式做實證研究，結果發現銀行貸款成長率和承辦貸款的主軸種類，確實會因總體經濟因素與銀行特徵而有所不同。總體經濟變數中以實質有效匯率和貸款行為較具關聯性，而銀行特徵中則是資本適足率和逾放比，當總體經濟和銀行特徵同時納入考量後，總體經濟變數的影響性則會變為不顯著，表示銀行體質特徵與銀行貸款行為的相關性更為顯著。此外，本研究亦發現在多數期間和貸款行為有所關聯性之變數，皆為銀行風險管理能力的指標，因此投資人可透過風險管理指標找出在貸款舉措上可能表現較良好或穩定的投資標的，然而在持續降息的貨幣寬鬆政策期間，和貸款行為有所關聯之指標除了風險管理能力外，更需要考量銀行的資本實力、盈利水平和銀行對於未來市場的展望。

The purpose of this study is to explore the relationship between macroeconomic conditions and bank characteristic and their bank lending behavior. The study uses data from 54 quarters spanning from 2010 to June 2023, with a sample comprising the top 30 banks based on size, and employs Ordinary Least Squares (OLS) regression for empirical analysis. The results show that bank lending growth and the primary types of loans are indeed influenced by both macroeconomic factors and banking characteristics. Among the macroeconomic factors, the real effective exchange rate and lending behavior have the most significant correlation. Regarding banking characteristics, capital adequacy ratio and non-performing loan ratio are the most significant. However, when both macroeconomic factors and banking characteristics are simultaneously considered, the relevance of macroeconomic variables becomes insignificant; suggesting that bank lending behavior is more correlated with banking characteristics than with macroeconomic factors. Additionally, the study reveals that the variables showing correlation with lending behavior over multiple periods are mostly indicators of banks' risk management capabilities. Therefore, investors can identify potential investments that may perform better or be more stable in loan measures through risk management indicators. However, during periods of prolonged interest rate cuts and loose monetary policy, the correlated indicators with lending behavior also encompass bank capital strength, profit levels, and banks' outlook on future markets.
