自2012年以来，中国在全国范围内对住宅行业实施了递增的区块电价（IBT）。然而，关于IBT设计的知识仍然有限，特别是如何确定IBT方案的第一个区块的电量。假设第一个区块应该根据某种程度的电力贫困来设置，我们试图模拟家庭电力需求，这样就可以建立基本需求的范围。我们发现，在中国家庭中存在一个阈值的电力消费相对于收入，这可以被认为是一个衡量电力贫困，农村和城市地区的阈值不同。对于农村（城市）家庭而言，第7（5）个收入十分位家庭的用电量可被视为基本需求的门槛或衡量用电贫困的一个尺度，因为农村（城市）地区的家庭用电需求在第7（5）个收入十分位之后才对收入变化作出反应。因此，一些省份的第一个IBT区块（例如，北京）似乎被设定在一个过高的水平。然而，随着时间的推移，鉴于持续的快速增长，IBT将开始更好地反映实际的基本需求。(C)2015爱思唯尔有限公司版权所有。
An increasing block tariff (IBT) has been implemented nationwide in the residential sector in China since 2012. However, knowledge about IBT design is still limited, particularly how to determine the electricity volume for the first block of an IBT scheme. Assuming the first block should be set based on some measure of electricity poverty; we attempt to model household electricity demand such that the range of basic needs can be established. We show that in Chinese households there exists a threshold for electricity consumption with respect to income, which could be considered a measure of electricity poverty, and the threshold differs between rural and urban areas. For rural (urban) families, electricity consumption at the level of 7th (5th) income decile households can be considered the threshold for basic needs or a measure of electricity poverty since household electricity demand in rural (urban) areas does not respond to income changes until after 7th (5th) income decile. Accordingly, the first IBT block for some provinces (e.g., Beijing) appears to have been set at a level that is too high. Over time however, given continued rapid growth, the IBT will begin to better reflect actual basic needs. (C) 2015 Elsevier Ltd. All rights reserved.
