企業環境社會責任（environmental corporate social responsibility, ECSR）在近年已是熱門議題，本文旨在討論肩負社會環境責任的技術領先廠商其生產技術在固定權利金及單位權利金兩種授權方式下的不同授權行為，對福利變動和市場均衡結果之影響。首先固定權利金下授權未必發生，授權後廠商利潤可能會下降，惟授權發生後廠商關心環境程度愈高則利潤有可能會增加；與未授權情境相較，福利變動方向未定。其次在單位權利金下，授權必定發生，此時授權廠商可能收取較成本差距小的單位權利金。最後與傳統認知不同，技術領先廠商可能會優先採取固定權利金而非單位授權金策略。

Environmental corporate social responsibility has become a hot topic in recent years. This article discusses the different licensing behaviors of the leading production technology manufacturer that shoulders social environmental responsibilities under the two licensing methods of fixed-fee and royalty, and the resulting changes in welfare and market equilibrium outcomes. First, authorization under a fixed-fee licensing may not necessarily occur, and the manufacturer’s profit may decrease post authorization. After the authorization occurs, the more the authorized manufacturer cares about the environment, the more profit may increase; compared with the unlicensed situation, the direction of welfare changes is uncertain. Second, under the royalty strategy, authorization must happen. At this time, the leading manufacturer may charge a royalty that is smaller than the cost gap. Finally, different from traditional cognition, the leading technology manufacturer may prioritize adopting a fixed-fee licensing rather than a royalty licensing strategy.
