摘要

本文探討在遞增階梯訂價法下，電價制度對台灣不同所得家庭的公平性探討，估計樣本為100年至102年的家庭收支與用電資料。首先，本文估計家庭用電量、電費支出、電費支出占所得比例以及補貼。其次，依序把前面的數據代入各項公平性指標內，由不同家庭的個人所得水準排序成五等分，觀察在夏月及非夏月，不同等分家庭對遞增階梯訂價法下的電費負擔的公平性程度。最後，本文由各項公平性指標，總結出遞增階梯訂價法對不同所得家庭對電費負擔的公平性。本文主要實證結果如下:

一、在遞增階梯訂價法下，所得水準最低的家戶得到的正補貼皆比所得最高等分的家戶來得多。反之，所得水準最低的家戶付出的負補貼皆比所得最高等分的家戶來得少。

二、在遞增階梯訂價法下，所得水準最低的家戶得到正補貼的家戶數皆比所得最高等分的家戶數要來得多。反之，所得水準最低的家戶得到負補貼的家戶數皆比所得最高等分的家戶來得少。

三、夏月所得水準最高與最低等分家庭的正負補貼差距皆比非夏月者來得高。

四、由Ω指標可看出，遞增階梯訂價法對於不同所得家庭其公平性是有發揮其作用，且重分配機能是累進的。

This paper discusses the impact of increasing block pricing on income allocation and fairness of residential electronic power. This analysis has been performed by using the Family Income and Expenditure data in Taiwan for 2011 to 2013. First, I study the effect of estimates household electricity consumption, electricity expenditure, the share of electricity expenditure and the subsidy under the increasing-block pricing. Second, I study the fairness of different aliquots family of tariff burden ladder under increasing block pricing in the summer months and the non-summer months. Final, the main findings are as follows the fairness of indicators on the impact of increasing block pricing:

1. In the increasing block pricing, is the lowest level of subsidy income households are to get more than the highest income of households.

2. In the summer months are more than the resulting level of subsidy gap between the highest and lowest sign all families than non-summer months.

3. The increasing block pricing is to play its role in fairness portion for different household on the Ω indicators
