基于变异系数和灰色层次分析法的CO2排放量影响因素分析

为探索CO₂排放量的影响因素及其各影响因素之间的相互关系，统计收集我国历年CO₂总排放量及各种影响因素的数据，将CO₂排放量的影响因素分为直接因素与间接因素两类.采用变异系数法、灰色关联分析法以及层次分析法对各类因素与CO₂排放量的影响关系进行了重要性与关联性分析.分析发现：天然气与其他能源消费总量是CO₂排放量增长的主要直接影响因素，全社会固定资产投资总额以及各产业国内生产总值是主要间接影响因素，同时，CO₂排放量与煤炭能源及我国传统3大产业之间关系最为密切.

An Analysis of the Influential Factors of CO2 Emission Based on Coefficient of Variation and GAHP

In order to explore the influential factors of CO₂ emission and the relationship between various factors, the statistics of total CO₂ emission and the influential factors of CO₂ in the recent years are collected. Meanwhile, the influential factors of CO₂ emission are classified into direct factors and indirect ones. By using Coefficient of Variation Method, Grey theory and Analytic Hierarchy Process (GAHP), the importance and relevance between the CO₂ emission and its various influential factors are analyzed. The results show that the total consumption of natural gas and other energy presents the main direct influential factors for the CO₂ growth, and total fixed asset investment of the whole society and the industry’s GDP are the main indirect influential factors. At the same time, the relationships between CO₂ emission and coal energy and the three major traditional industries in China are closest.
