為了克服農家農場土地面積細小且分散所導致的無效率農業經營，與提升台灣農業之競爭力，政府仍採取農地集團化利用之政策。本文基於治理理念，探討我國農地集團化利用之背景與四個治理模式，包括民國六十一年的農業生產專業區、民國七十三年的農地利用綜合規劃之組織、民國九十四年之稻米產銷專業區與民國九十五年農業經營專區，並比較上述四種農地集團化利用治理模式之特質，比較結果得知，於愈來愈競爭的環境下，農地集團化利用之治理模式，已由早期偏向官僚層級的混合型治理模式逐漸轉偏向市場之混合型治理模式，以適應市場上競爭之需要，更重要的是，動態環境與制度環境以及制度安排間是有交互影響關係。

台灣自第一階段農地改革後，逐漸有為降低生產成本與提高農民收入之大規模策略出現。本研究定義出台灣歷經包括農業生產專業區、農地利用綜合規劃之共同經營班與其後之產銷班、稻米產銷專業區與農業經營專區等四種大規模策略之農地集團化利用階段，是在公共秩序之法規命令，與集團成員契約簽訂所建立之私人秩序下而得以成立運作，符合混合式治理的特徵；而此治理理念的應用，可以新制度經濟學中微觀的角度，對組成各階段公共秩序和私人秩序的規則和執行機制，進行治理結構之比較分析。此係分別展現公共秩序與私人秩序規則中，誘因和安全措施是如何的賦予，與集團運作時是藉由第三者執行或自我執行之執行機制，以分析各農地集團化利用階段所採行的混合式治理，其治理結構如何具有階層與市場屬性程度的差異，進而探討所呈現的變遷趨勢，供政府對農地集團化利用輔導之策略擬定，與營運主體設計契約化私人秩序時之參考。研究發現在市場越來越競爭之下，台灣各農地集團化利用階段之治理結構，不僅於規則中誘因的提供與安全措施的設置朝向由私人秩序賦予，更從集團之規劃召集、與集團成員行動的裁決等，都趨向依私人秩序訂定條款，由集團成員自我執行。故政府對農業經營的混合治理，在逐漸有由營運主體自發地根據公共秩序組織集團，擬定私人秩序自我執行運作的趨勢下，建議可增強公共秩序需對私人秩序治理結構之支持，並於公共秩序執行排除考量給予改善之機會，讓農地集團化利用更具競爭力與建立永續發展的空間。 / In Taiwan, after the first farmland reform, an integrated strategy has been adopted to pursue lower production cost and higher agricultural profit. This study defines four stages of integrated farmland use in Taiwan, i.e. Agricultural Production Special District, Agriculture Production Section and Production Group, Rice Production Special District, and Special Agriculture Enterprise District. Those stages of integrated farmland use have characteristics of hybrid governance which are established under laws i.e. public ordering and contracts among members of groups i.e. private ordering. The idea of hybrid governance, derived from the New Institutional Economics, is a micro-analytic point of view and can be employed to conduct a comparative study on governance structures. The governance structures, namely the rules and the enforcement mechanism in the public and private ordering of every stage, are analyzed and compared. How incentives and security measures are adopted in the rules and whether third party enforcement or self-enforcement is used in the enforcement mechanism of the public and private ordering are provided. After the analysis of hybrid governance structures, differences on their hierarchy and market orientation will be revealed. In Taiwan the governance structures of integrated farmland use has a tendency of market orientation and private ordering. The result can be considered by the government in deciding the policies for integrated farmland use, and can help the operating group to formulate private contracts for their own private ordering.
