辽宁省能源消费和碳排放与经济增长的关系

The relationship between energy consumption and carbon emissiont with economic growth in Liaoning Province

在广泛收集资料的基础上,对辽宁省的能源利用效率、能源消费强度与经济增长的关系进行探索,其目的为辽宁省的节能与CO2减排及经济的快速发展提供科学依据。结果表明:辽宁整体单位GDP能耗高出全国水平52%—70%,第二产业单位GDP能耗是第三产业的5.67—8.41倍,第一产业的7.2—9.0倍;辽宁能源利用率只有全国平均水平的60%左右,第二产业能源利用效率只有第一产业的11.89%,第三产业的12.60%;GDP年增长速率大于能源消费量年增长速率,能源投入增加促进了国民生产总值的提高,但是经济增长并不是完全依赖能源消费的增长;能源消费量与经济增长的关系,呈现出"N型"曲线特征,随着GDP的增加,能源消费量出现反复上升和下降过程,辽宁省能源消费和经济增长关系没有达到长期的均衡性,尚处于非平衡的发展阶段。

In order to provide the scientific basis for saving energy,reducing CO2 emissions and promoting the rapid development of economy of Liaoning Province,the Gross Domestic Product（GDP） and CO2 emissions were surveyed and the relationship between economic growth and energy utilization efficiency,energy consumption intensity was analyzed in this study.The results showed that total energy consumption in second industry was extremely high,which was 5.67—8.41 times higher than that of the third industry,and 7.2—9.0 times higher than that of the first industry.The energy consumption per unit capita of GDP was 52%—70% higher than the national average level,mainly due to concentrated high energy demanding industries,such as coat mining,dressing,electricity and supply,etc.Besides,the energy utilization efficiency of second industry was quite low,equivalent to 11.89% of the first the industry,12.60% of the third industry.Although annual GDP growth rate was faster than the growth rate of energy consumption,which might indicate the increased energy input promoted the improvement of gross domestic product,economic growth is not completely dependent on energy consumption growth.Instead,the adjustment of industrial structure and technical innovation played a critical role on the development of economy in Liaoning.CO2 emissions and annual change of per capita GDP presented turning point in 2001 and 2005,with the increase of per capita GDP,emissions of CO2 appeared to fluctuate repeatedly,suggesting the relationship between environment and the economy in Liaoning is still not in the balanced and collaborative developing stage.To solve these issues,structure adjustments,technology innovation and reform were needed to improve energy utilization efficiency and improve economy.
