基于最终需求视角的中国碳排放分析

Analysis of China's Carbon Emissions:Based on Final Demand Perspective

基于最终需求的研究视角,运用投入产出模型,测算了居民消费、资本形成和出口所导致的碳排放。结果表明,2007年中国农村居民消费、城镇居民消费、政府消费、固定资本形成、存货增加、出口所导致的碳排放量分别占各行业碳排放总量的5.29%、17.08%、5.51%、38.39%、1.83%和31.91%。平均而言,农村居民和城镇居民每1元的消费支出分别导致所有行业总计排放0.18和0.196千克的CO2;每1元的固定资本形成导致所有行业总计排放0.3千克的CO2;每1元的出口导致所有行业总计排放0.28千克的CO2。

Based on the perspective of final demand, we use the input-output model to measure carbon emissions caused by household consumption, capital formation and exports in China. The results show that carbon emissions caused by rural residents＂ consumption, urban residents＂ consumption, government consumption, fixed capital formation, increase in inventories, and exports in 2007 respectively account for 5.29%, 17. 08%, 5. 51~, 38. 39 %, 1. 83%, and S1. 91% of the total carbon emissions from all industries. On average, one Yuan RMB consumed by rural residents or urban residents led to 0. 18 kg or 0. 196 kg of CO2 emissions, one Yuan RMB of fixed capital formation or export cause 0.3 kg or 0. 28 kg of CO2 emissions from all industries.
