台灣對現行的立委選制,一直不斷地加諸反省與檢討,並對未來可能取代的選制進行前瞻性評估,以為選制變遷合法化的基礎。本文乃射準這項立委選制變遷的演展,首先試圖找到原本選制,在過往實踐的過程上,已產生的各項異例,以及主權者對立法院的主觀評價,論證制度變遷的推動力量。 本文的第二個焦點在於:針對立法院於民國九十三年八月二十三日所通過,而尚待任務性國代複決的新選制,進行制度因子的剖析,並提出可再深化的制度面向,以及新制本身並未觸及的課題。 接著本文對新制進行前瞻性評估,指出單一選區制,業已在先進民主國家發生的後遺症,提醒職司當局的關注,進而採取相對應的舉措,杜絕在台灣發生類似的現象。
The paper takes aim at analyzing the change of legislator's electoral system in Taiwan. The first focus of this paper is concentrated on addressing anomalies arising during implementation of the existing system and disclosuring perceptions of the ruled to their congress. The second discourse is to anatomize and decompose the newly legitimatized electoral system. In addition, anatomization and decomposition also provide institutional dimensions which can be strengthened. The final part of this paper is to do prospective institution evaluation and try to find some of drawbacks implied in single-member-plurality-district-system. This finding can be utilized a basis to direct institutional implementation in order to avoid its derailment.
