目的：美容醫學現今已是百花齊放、百家爭鳴之發展，建構出一套適合美容醫學競爭力指標系統，對經營管理者及衛生主管機關至為重要，在未來擬訂醫療服務政策之參考。方法：主要以國家競爭優勢「鑽石模型」理論的觀點，透過10位專家學者進行三次德菲法問卷調查，利用層級分析法，將回收問卷整理後，以Excel 2013和Expert Choice決策支援軟體，進行一致性及指標權重等統計分析，建構出美容醫學競爭力指標系統。結果：美容醫學競爭力六項構面，一致性比率檢定為0.007是符合研究之要求，影響指標權重值與重要性之排序1至6，依序為需求條件之權重0.214；生產要素之權重0.185；相關及支援供應產業之權重0.180；企業策略、結構和同業競爭之權重0.161；機會之權重0.145；政府之權重0.116。結論：綜合專家學者所填答，「需求條件」是發展美容醫學重要的關鍵構面，其次是「生產要素」構面。滿足顧客的偏愛，在物質上、精神上、環境上、安全上、技術上的滿意，為前兩項關鍵構面指標，可為美容醫學中心或診所帶來獲益，故具備發展美容醫學之競爭力的關鍵指標因素。

Objective: The development of aesthetic medicine is highly diversified. This study constructed a competitiveness indicator system suited for aesthetic medicine that can serve as a key reference for business managers and health authorities in formulating medical service policies. Methods: This study was primarily based on the ＂diamond model＂ theory of national competitive advantage. A three-round Delphi questionnaire was completed by a panel of 10 experts. After using the analytic hierarchy process to organize the responses, Expert Choice and Excel 2013 were employed as decision support software to analyze the consistency and indicator weights and construct a competitiveness indicator system for aesthetic medicine. Results: The consistency ratio of the six dimensions of aesthetic medicine competitiveness was 0.007, which met the study requirements. Regarding the relationships between the sequence of weights, demand conditions was ranked first in affecting the importance between the indicators (0.214) and production factors was ranked second (0.185), followed by relevant and supporting supply industries (0.180); corporate strategy, structure, and horizontal competition (0.161); opportunity (0.145); and government (0.116). Conclusion: In summary, ＂demand conditions＂ was considered by the experts as the key dimension for the development of aesthetic medicine, followed by ＂production factors.＂ Satisfying the customers' preferences and achieving their material, spiritual, environmental, safety, and technical satisfaction were indicators of the two aforementioned key dimensions. Because these indicators can help improve the profitability of an aesthetic medicine center or clinic, they are crucial for developing competitiveness in aesthetic medicine.
