本文采用全要素框架考察了1980-2005年间23个发展中国家的能源效率。利用数据包络分析（DEA）窗口，可以在横截面和时变数据中测量效率，探索全要素能源效率及其变化趋势。实证结果表明，博茨瓦纳，墨西哥和巴拿马在能源效率方面表现最好，而肯尼亚，斯里兰卡，叙利亚和菲律宾在整个研究期间表现最差。七个国家的能源效率随着时间的推移几乎没有变化。11个国家的能源效率持续下降。在全要素能源效率持续提高的五个国家中，中国的提高速度最快。中国的实践表明，有效的能源政策对提高能源效率起着至关重要的作用。Tobit回归分析表明，全要素能源效率与人均收入之间存在U型关系。
This paper uses a total-factor framework to investigate energy efficiency in 23 developing countries during the period of 1980–2005. We explore the total-factor energy efficiency and change trends by applying data envelopment analysis (DEA) window, which is capable of measuring efficiency in cross-sectional and time-varying data. The empirical results indicate that Botswana, Mexico and Panama perform the best in terms of energy efficiency, whereas Kenya, Sri Lanka, Syria and the Philippines perform the worst during the entire research period. Seven countries show little change in energy efficiency over time. Eleven countries experienced continuous decreases in energy efficiency. Among five countries witnessing continuous increase in total-factor energy efficiency, China experienced the most rapid rise. Practice in China indicates that effective energy policies play a crucial role in improving energy efficiency. Tobit regression analysis indicates that a U-shaped relationship exists between total-factor energy efficiency and income per capita.
