本研究探討主流永續投資策略之基金是否較非使用主流永續投資策略之基金有較佳之風險調整報酬。結果顯示，CAPM模型中，有採主流永續投資策略之基金並不具較佳的Alpha表現，在將穩健性檢定下，也得出並採用主流永續投資策略與Alpha間並無顯著關聯。

The study examines whether funds with mainstream sustainable investing strategies have better risk-adjusted returns than funds that do not use mainstream sustainable investing strategies. The results show that in the CAPM model, funds that adopt mainstream sustainable investment strategies do not have better Alpha performance. Under the robustness test, it is also concluded that there is no significant correlation between adopting mainstream sustainable investment strategies and Alpha performance.
