有別於一般政策研究學者之認為政府組織是一個制度化的決策環境，本文以為民國 八十年代以來我國的政治決策環境，由於立法委員自我意識的高張，決策自主能力的增強， 加上社會多元利益團體遊說形響的機會與能力也大為增加，制度上經常充斥著偏好錯置、技 術混沌、以及決策者流動性參與的雜亂失序狀態。也正因為這種制度化失序狀態的存在，組 織決策的達成並不一定會依循傳統「問題→方案→決策」的程序，有時候也會受到某些機會 因素的影響而隨機產出。本文從立法院法案制定過程的案例研究當中就證實這種機會決策的 觀點。

　　　　　Different from the traditional point of view that government is a well- nstitutionalized decision-organization, this study regards the government as an institution with organized anarchy, full of problematic preferences, unclear technology and fluid participation, which is due to the congressmen's growing self-awareness, increasing power in law-making, and the expansive influence of various societal interest groups on government's policy-decision since the 90's. And because of the organized anarchy, government's policymaking does not always proceed through the rational process of "problem defining-alternative designing-legislating" but sometimes reach the agreement immediately after some critical political issues or precarious social events, which is validated by this research through the case study of two legislative decision-makings.
