能源弹性是分析经济增长与能源生产、消费增加之间关系的重要指标。选取了2001～1010年我国煤炭、石油、天然气和水电、核能的生产、消费弹性作为数据样本,通过建立灰色关联度模型,得出煤炭、石油、天然气及水电、核能的生产弹性与总能源生产弹性的关联度分别为0.708946,0.669974、0.765697、0.676101,煤炭、石油、天然气及水电、核能的消费弹性与总能源消费弹性关联度分别为0.708946、0.669974、0.765697、0.676101。在能源生产弹性和消费弹性中,煤炭和天然气的关联度并不具有完全的一致性,建议加大对天然气这种新型清洁能源的开发、利用,现阶段应大力发展洁净煤技术,提高煤炭的燃烧效率,减少环境污染;目前石油的生产、消费弹性与总能源生产、消费弹性的关联度均为最低,建议应适度提高石油使用水平;水电、核能与总能源弹性关联度不高,建议目前应加大科研力度。
Energy flexibility is an important indicator of the relationship between economic growth and energy production and consumption. By selecting the production and consumption elasticity of China’s coal, oil, natural gas, hydropower and nuclear energy from 2001 to 2010 as the data samples, the paper establishes the gray relational degree model to get the production elasticity of coal, oil, natural gas, hydropower and nuclear energy and total energy production The elastic correlations are 0.708946,0.669974,0.765697,0.676101 respectively. The elastic correlations between the consumption elasticity of nuclear energy, oil and natural gas, hydropower and nuclear energy and total energy consumption are 0.708946,0.669974,0.765697,0.676101 respectively. In the energy elasticity of production and consumption elasticity, the correlation between coal and natural gas is not completely consistent, it is proposed to increase the development and utilization of new clean energy such as natural gas, at this stage should be to develop clean coal technology, improve coal Combustion efficiency and reduce environmental pollution; At present, the correlation between oil production and consumption elasticity and total energy production and consumption elasticity are the lowest, suggesting that oil use level should be moderately increased. The correlation between hydropower and nuclear energy and total energy elasticity is not high, Should increase research efforts.
