摘要


本研究以1990年到2014年美國Compustat非金融業上市公司為樣本,探討公司議價能力與權益資金成本之間關聯所在。實證發現議價能力會與權益資金成本呈負相關,顯示議價能力強的公司會利用其優勢改善其交易條件,讓其盈餘波動相較穩定,進一步降低權益資金成本。此外,議價能力也會與系統風險中的市場貝他呈現顯著負相關,顯示議價能力對於權益資金成本的下降主要透過市場風險的下降。再更進一步依照規模和市場競爭程度大小分組,分別探討規模和市場競爭程度會對議價能力與權益資金成本關係的影響,發現議價能力與權益資金成本的負向相關在規模小的公司間更為顯著。

The thesis investigates the correlation between a company’s bargaining power and cost of equity by adopting Compustat non-financial firms during 1990 to 2014 as the original study sample. Empirical results show that bargaining power is significantly and negatively correlated to the cost of equity, revealing that companies with stronger bargaining power uses their advantages to improve transaction condition to stabilize earning volatility, and further to cut down cost of equity capital. Further, this study finds that bargaining power is also significantly and negatively correlated to market beta. Finally, the influences of bargaining power on cost of equity and systematic risk are investigated by different levels of firm size and market competition. The results show that the negative relationship between bargaining power and cost of equity and market beta are stronger for small-sized companies.
