立法院內的公共政策制定，通常被描並應循某種邏輯過程。首先，立委們察覺到問題，然後評估問題成因，並儘快通過新法案以有效回應政策問題。本主旨在探討此一邏輯過程。透過對立委們黨派動態、委員激勵、及所有可能的方案組合分析，本主預測立委們將不會依照問題界定、方案產生、方案評估此一邏輯過程來處理問題。取而代之的是，唯有問題與解決方案的特殊組合，在某種抉擇的情形下，立委們才可能著手解決政策問題。

The process of public policymaking in Legislative Yuan has commonly been depicted in a prescribed logical routine. At first, policy problem captures the attention of legislators. Next, legislators assess that problem and its causes and to respond as efficiently as possible through new legislative enactments. Seeking to address this natural logical sequence, this article systematically examines the member's incentives, group dynamics, and potential combinations of alternatives in new Legislative Yuan, and predict that legislators tend to not go through a logical routine: defining the problem, generating the possible solutions, evaluating the alternatives Rather, legislators work on policy problems only when a specific combination of problem and solution in a choice situation makks it possible.
