碳排放与能源消费和经济增长的灰色关联分析

中国碳排放问题成为世界关注的焦点问题。研究碳排放与经济增长、能源消费关系有助于实现2020年碳减排目标。选取2001～2009年碳排放与能源消费、经济增长数据,运用灰色关联分析模型,分别计算碳排放与能源消费、经济增长的灰色关联度。研究结果表明,无论是从折线的相似程度还是相对于始点变化速率的接近程度来看,碳排放曲线与能源消费曲线、经济增长曲线十分相似,说明碳排放与能源消费、经济增长之间存在紧密联系。

Grey Correlation Analysis on Carbon Emissions, Energy Consumption and Economic Growth

Carbon emissions in China have become the focus of world attention.Study on the relationship among carbon emissions,energy consumption and economic growth can help to achieve the carbon reduction targets in 2020.This article selects data about carbon emissions,energy consumption and economic growth during 2001～2009,uses grey correlation analysis model to calculate the grey correlation grade among carbon emissions,energy consumption and economic growth.The results show that curve of carbon emissions is very similar to that of energy consumption and economic growth,from the degree of poly-line similarity as well as proximity relative to the starting point change rate.It indicates that there exists a close relation among carbon emissions,energy consumption and economic growth.
