Data for: Global energy use: Decoupling or convergence?

Abstract of associated article: We examine the key factors driving change in energy use globally over the past four decades. We test for both strong decoupling where economic growth has less effect on energy use as income increases, and weak decoupling where energy use declines overtime in richer countries, ceteris paribus. Our econometric approach is robust to the presence of unit roots, unobserved time effects, and spatial effects. Our key findings are that the growth of per capita energy use has been primarily driven by economic growth, convergence in energy intensity, and weak decoupling. There is no sign of strong decoupling.

关联论文摘要：本研究聚焦过去四十年来全球能源消费变化的核心驱动因素，同时检验两类脱钩情形：其一为强脱钩，即随着收入水平提升，经济增长对能源消费的影响逐渐减弱；其二为弱脱钩，即其他条件不变时，富裕国家的能源消费随时间推移呈下降趋势。本研究采用的计量分析方法可稳健应对单位根、不可观测时间效应以及空间效应带来的干扰。核心研究结果表明，人均能源消费增长主要由经济增长、能源强度趋同与弱脱钩效应驱动，未发现强脱钩的相关迹象。
