“电力弹性系数”是一个老话题：说它“老”就是在几十年来的电力发展中常被人们议论和研究，是在一直作为电力需求预测的方法被人们接受和使用。“电力弹性系数”又是一个新课题：“新”就新在当前国民经济结构性调整使电力弹性系数研究远远超过了“大于 1”或“小于 1”的范? “Electricity Elasticity Coefficient” is an old topic: to say that it is “old” is often discussed and studied by people in the development of electricity for decades. It has been accepted and used by people as a method of forecasting electricity demand. “Electricity Elasticity Coefficient” is also a new topic: “New” is new. In the current structural adjustment of the national economy, the study of the power elasticity coefficient has far exceeded the “greater than 1” or “less than 1” range.
