臺灣地方民選行政首長熱衷舉辦各種文化活動，而且大多數採用契約委外由民間廠商承辦，往往耗費巨資卻鮮少進行較嚴謹的績效衡量。本文採用績效觀感的研究途徑，並依據文化活動的複雜性質，發展出創新、負責、品質與效能等四項衡量文化活動契約委外階段的核心績效指標，進一步運用地方客家節慶包括傳統典慶（義民祭）與現代慶典（桐花祭）為經驗研究對象，透過委託人－代理人架構，針對契約委外的客家行政機關、承辦廠商以及地方公民團體和參與民眾等利害關係人進行訪談，分析它們對於客家文化活動的績效觀感，並深入探討績效觀感之間的差距及其原因，並根據文化活動契約委外的研究發現，提出提升績效的建議。

Taiwan's elected local administrative leaders have been keen to organize cultural campaigns, most of which are contracting out to private vendors. However, given the large amount of money spent, rigorous performance measurements are often lacking. Based on the complex nature of cultural campaigns, this article employed perceived performance approach and developed four core performance indicators to measure innovation, accountability, quality and effectiveness in outsourced cultural campaign stages. The article targeted local Hakka festivals, including traditional festivals (Yi-Ming Festival) and contemporary festivals (Tong Blossom Festival). Using a principal-agent framework, this article interviewed stakeholders including the Hakka administrative agencies contracting out the campaigns, the contractors, local nonprofit organizations and participating public to determine their perceptions of campaign performances. Furthermore, the reasons for differences in performance perceptions are also explored. Finally, according to the research findings on the outsourced cultural campaigns, this article recommended policy suggestions and institutional revision to improve performances.
