1970年代興起的新公共管理帶來「公私協力」模式，同時使得我國在1990年代開啟一連串教育改革，而體制外之教育需求—實驗教育及家長教育選擇權，開始逐步受到政府重視，並使實驗教育走向合法化。直至2014年立法制定實驗教育三法—公辦公營學校方式、公辦民營學校方式、非學校型態方式，更使實驗教育走向興盛化，截至109學年度我國已有13所公辦民營學校，較過去幾乎成倍數成長。公辦民營學校即為公私協力代表類型之一而本文所探討的個案學校即為實驗教育三法通過後，首次出現協力失靈的案件，惟目前公辦民營學校之協力失靈相關文獻仍不充足。據此，本文使用文件分析法，來探進行探討，並得出以下結論：代理人理論可用於解釋本次解約事件、現行政策環境與法令仍限制實驗教育、協力夥伴關係尚待建立。

The trend of New Public Management in 1970s urged each government to care about demands from citizens and the quality of public service so much that Public-Private Partnerships (PPP) showed up. Likewise, education reform in Taiwan began in 1990s, so experimental education and school choice were emphasized as well. Taiwan didn’t legislate 3 laws for experimental education— public school、privatized schools and non-school until 2014. Up to 2020, there are 13 privatized schools in Taiwan. However, due to the lack of concerned literature to discuss Collaborative Partnership between the local government and private sector, this study chose one case school that terminated by one local government and applied documentary analysis to explain possible reasons. Finally, some results present as follow: This case can be explained through agency theory, decision-making environments and modern regulations restrict experimental education and collaborative partnership needs establishing.
