青海省主要能源消费碳排放影响因素及脱钩效应研究

Analysis of Factors Influencing Carbon Emissions from Energy Consumption in Qinghai Province and the Decoupling Effect

通过2010-2021年的能源消费相关数据和能源消费碳排放量,利用LMDI模型对青海省煤炭、石油、天然气等三种主要能源消费碳排放量进行分解,利用脱钩模型分析青海省经济增长与主要能源消费碳排放量的脱钩关系。研究发现:青海省经济增长与主要能源消费碳排放量总体上处于弱脱钩状态;能源强度效应是抑制主要能源消费碳排放的主要因素,产出效应和人口规模效应对主要能源碳排放量的增长具有促进作用但影响较小。

Based on energy consumption data and carbon emissions from 2010 to 2021,the LMDI model was used to decompose the carbon emissions of three main energy sources in Qinghai Province,including coal,oil and natural gas.The decoupling model was used to analyze the decoupling relationship between economic growth and carbon emissions from major energy consumption in Qinghai Province.Research has found that the overall economic growth and carbon emissions from major energy consumption in Qinghai Province are in a weak decoupling state.The energy intensity effect is the main factor that suppresses carbon emissions from major energy consumption,while the output effect and population size effect have a promoting effect on the growth of carbon emissions from major energy sources,but their impact is relatively small.
