隨著經濟的發展，國民所得增加生活水準的提昇，電力的重要性與日俱增，而最適電價的訂定，則成為政府當局及學者們所關切的課題。因此，本文旨在分別就資訊對稱與資訊不對稱下靜態兩種情況，進行最適電價管制模型之研究，以期達到社會福利最大化之目標。

本研究首先對於電力事業所具備的特性，加以闡述。同時由於電力事業係屬公用事業，電價的影響層面又既深且廣，並具有自然獨占之屬性，因此政府管制當局通常採取價格管制措施介入市場。本文將就常見之單一定價模式及尖離峰定價模式，作一扼要說明。

其次，先就探討資訊不對稱之相關文獻，稍作概述。並將針對資訊對稱與不對稱下，產生道德障礙、逆選擇、和成本浮報等問題之靜態最適電價模型，與產生道德障礙之動態最適電價模型，作深入探討。且將就所得結果之政策涵義，作一評論。最後，對未來研究發展之方向提出建議。
