雖然公共外交已行之有年，但隨著科技的革新和非國家行為者的崛起等國際社會的改變，公共外交的策略與手段勢必面對一番調整與改變。對於受制於傳統政治、地理位置、權力等中小型國家，這番外交的變革所帶來的並不僅僅是挑戰，更是機會與創新。這些國家藉由這些變革，發展出獨特的外交策略並拓展其在國際領域上的影響力。而藉由提供援助和救濟、致力於維護人類福祉的人道外交，是中小型國家採取的外交手段之一。為了有進一步的探討，本研究聚焦於挪威、土耳其、和台灣做為比較案例，並分析其人道外交背景、策略、和手段。 / Public diplomacy is not a new phenomenon in the history, yet with the changing features in the 21st century, such as the rise of the non-state actors and the technology advancement, the strategies and practices of public diplomacy have also been adjusted and modified. For small and middle size states that are constrained by power, politics, or geographic location, the changing environment has brought them both challenges and opportunities. They are able to develop diplomatic strategies beyond these hindrances through concentrating resources in specific areas that best able to increase the influence and visibility on the global stage. In this regard, humanitarian diplomacy is one of the niches that small and middle size states adopt to carry out their foreign policy goals, while generating awareness and providing assistance for areas suffering from severe humanitarian conditions and political conflicts. To further the study and to shed light on how small and middle size countries adopt humanitarian diplomacy as their diplomatic niches, the three cases, Norway, Turkey, and Taiwan, are selected and compared in terms of background, strategies, and practices. The comparison indicates that different countries develop their diplomatic strategies and practices based on state’s characteristics and existing resources. However, under the notion of public diplomacy, there are still several essential requirements needs to be examined in order to “make each punch above its weight.”
