本研究考察了1996年至2016年期间欧盟居民和工业用电需求的短期和长期价格和收入弹性。工具变量模型使用之间的估计，以及动态面板模型提出了强大的估计，并评估不同的方法对报告的弹性的影响。居民用电量的长期价格弹性估计在-0.53和-0.56之间。这些弹性比工业用电的弹性更缺乏弹性，据报道，工业用电的弹性在-0.75到-1.01之间。选择不同的计量经济学方法对估计数的影响不大。虽然长期居民收入弹性估计是适度缺乏弹性，估计约为0.61，工业用电往往与收入密切相关，弹性在0.76和1.08之间。所有部门的电力需求在短期内都高度缺乏价格和收入弹性。此外，人口密度、温度和政策措施也影响部门用电。上述估计可以帮助欧洲能源和环境政策的设计。
This study examines the short- and long-run price and income elasticities of residential and industrial electricity demand in the European Union between 1996 and 2016. Instrumental variable models using the between estimator, as well as dynamic panel models are employed to present robust estimates, and to assess the impact of different methodologies on the reported elasticities. The long-run price elasticity of residential electricity consumption is estimated between -0.53 and -0.56. These elasticities are more inelastic than that of industrial electricity use, which is reported between -0.75 and -1.01. The choice of different econometric methodologies has only moderate impact on the estimates. While long-run residential income elasticity estimates are moderately inelastic and estimated around 0.61, industrial electricity use tends to be closely tied to income, with elasticities between 0.76 and 1.08. Electricity demand in all sectors is highly price and income inelastic in the short run. Additionally, population density, temperatures, and policy measures also influence sectoral electricity use. The above estimates can aid the design of European energy and environmental policy.
