摘要

數量與價格競爭之議題已持續多年，過去有學者加入各種因素，例如:成本、勞力、研發、市場規模、資本額等各種更符合經濟現實面的狀況做探討。近年來更有學者研究日本製造業競爭模式，認為Cournot提出的數量模型概念雖然簡單明瞭，但是在計量經濟分析結果，發現市場採用Cournot競爭卻是較少發生的。本研究蒐集台灣製造業相關資料，分析台灣製造業在整體研發上偏向數量或是價格競爭，並使用迴歸檢定的方式作進一步檢驗。研究結果發現，台灣製造業在研發方面傾向採用混合式的競爭方式，意指同時採用Cournot 與Bertrand的競爭策略。本研究提供與以往不同之研究角度，以整體產業實證方式，闡明台灣製造業在研發策略上之競爭型態。

Cournot (quantity) and Bertrand (price) models have been utilized to explore market competition for a long tradition. Some studies revealed that Cournot competition was simple yet clear with common sense notions; however, quantity strategy seemed rare and less adopted in the market. The study utilized Taiwanese datasets to empirically verify the type of R&D competition of the Taiwanese manufacturing industry. The results demonstrated that Taiwan manufacturing enterprises tended to use a Hybrid method, i.e., both price and quantity strategies in R&D. The econometric results give a different perspective when one analyzes business competitive strategies in a market.
