全要素能效(TFEE)评价在运筹学和能源经济界受到越来越多的关注。早期的TFEE研究隐含地假设生产活动位于经济区域，这排除了生产活动位于非经济区域从而遭受拥堵的可能性。本文的研究有助于建立考虑拥堵影响的TFEE指标。从拥堵生产技术的定义入手，提出了几种数据包络分析模型，并在此基础上构建了拥塞TFEE指标。在此基础上，建立了由拥塞效应引起的能源低效量化模型。应用该指标体系对2010-2012年我国省级工业部门的能效绩效进行了评价。研究发现，在拥堵的情况下，TFEE可以为选择适当的方式来实现能源效率的提高提供有益的见解。与无拥塞生产技术下的实验结果比较表明，当拥塞效应确实存在时，忽略拥塞效应可能会导致显著不同的TFEE得分。
Total-factor energy efficiency (TFEE) assessment has received increasing attention in both operations research and energy economics communities. Earlier TFEE studies implicitly assume that production activity lies in the economic area, which precludes the possibility that the production activity lies in the non-economic area and thus suffers from congestion. This paper contributes to develop TFEE index by taking into account congestion effect. It starts with the definition of congested production technology, based on which several data envelopment analysis models are proposed to construct TFEE index with congestion. The models for quantifying energy inefficiency caused by congestion effect are also developed. We apply the proposed index to evaluate the energy efficiency performance of Chinese industrial sectors at province level in 2010–2012. It is found that TFEE with congestion can yield useful insights about the choice of proper ways to achieve energy efficiency improvement. A comparison with the empirical results under congestion-free production technology indicates that ignoring congestion effect may lead to significantly different TFEE scores when congestion effect does exist.
