摘要

本文通过研究能源需求的收入弹性是否随经济发展水平而变化，重新审视了有关能源需求收入弹性的经验证据。我们使用均值组类型的估计方法对三十年间 111 个国家的样本进行了估计。我们的分析表明，该弹性并非恒定不变，而是随着国家变得越来越富裕而趋于下降。随着经济体越来越发达，其能源强度也会下降，最终达到零弹性，这表明经济增长与能源需求之间存在脱钩。这一发现强调了在预测能源前景时考虑各国经济发展阶段的重要性。

Does the income elasticity of energy demand vary with the stages of economic development?

This paper revisits the empirical evidence on the income elasticity of energy demand by investigating whether it varies with the level of economic development. We estimate the elasticity using mean-group type estimators for a sample of 111 countries spanning three decades. Our analysis reveals that the elasticity is not constant and tends to decline as countries become wealthier. As economies become more developed, their energy intensity falls, eventually reaching zero elasticity, indicating a decoupling between economic growth and energy demand. This finding underscores the importance of considering countries’ stages of economic development when making energy outlook projections.

期刊介绍： Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
