能源生产弹性系数和消费弹性系数
能源生产弹性系数和消费弹性系数能源弹性系数说明能源数量对经济增长的反应性。它是反映经济发展变化引起能源数量相对变化的指标。能源数量可分为生产量和消费量,因而能源弹性系数也分为能源生产弹性系数和能源消费弹性系数。能源生产弹性系数或消费弹性系数,表示经济总量增长1%,相应的能源生产量或消费量增长百分之几,以反映能源生产量或消费量增长与经济总量增长之间的关系。其计算公式分别为:能源生产弹性系数能源消费弹性系数一瞥灌鬓黔进矍纂鲁赣叫擅肇率上式中,西方国家一般采用国民生产总值来计算经济总量增长率。 从西方国家经济发展情况来看,在工业化初期,能源消费弹性系数一般都大于1;实现工业化或工业有较大发展以后,一般都小于1。
