中国农村居民生活间接能源消耗与碳排放分析

Analysis to the Indirect Energy Consumption and Carbon Emissions by Chinese Rural Residents

通过编制能源环境投入产出表,结合农村居民消费支出数据,计算了2000～2007年我国农村居民八项消费支出的间接能耗强度系数、碳排放强度系数,进一步测算了由农村人均生活消费支出及农村五个收入组居民人均消费支出所诱发的能源消耗量及碳排放量。结果表明,由农村居民生活消费诱发的间接能耗量及碳排放量远高于其生活直接能耗量及碳排放量;农村居民的居住、家庭设备用品支出所诱发的能耗量及碳排放量在总能耗及总碳排放中所占比重逐年加大,至2007年,此二项的能耗比重及碳排放比重值分别达到了63.03%及63.2%;居民基本生活消费支出之一的食品,其诱发的能耗量及碳排放量有逐年下降的趋势;居民生活消费诱发的能耗量及碳排放量与其收入水平表现较强的正相关性,即收入水平越高,其能耗量及碳排放量也越大;技术水平的改进有利于能耗强度系数及碳排放系数的降低,进而减少能耗量及碳排放量。

The paper first drows up an Energy-Environmental input-output model, then combines with the data from rural household survey, it calculates the indirect energy intensity and carbon intensity of eight kinds of expenditure during 2000-2007,and further more, it estimates the energy consumption and CO2 emissions from the expenditure per captia of rural and the expenditure per captia of rural five different income gap. The results show that,the amount of energy consumption and CO2 emissions from direct rural household consumption is far more than that from indirect consumption; The dwelling and equipments expenditure cause 63.03% energy consummption and 63.2% CO2 emission;The energy consumption and CO2 emissions from food expenditure is slowed down a little in these years; there is a high relevance between the amount of energy consumption and CO2 emission; techology is a good fact because it can reduce the energy intensity and CO： intensity,then reducing the energy consumption and CO2 emissions.
