【摘要】：全球變暖已成為當(dāng)前人類面臨的嚴(yán)重環(huán)境問題。目前國際社會(huì)已經(jīng)普遍認(rèn)為人類活動(dòng)產(chǎn)生的溫室氣體特別是C02是導(dǎo)致全球變暖的主要原因。隨著經(jīng)濟(jì)社會(huì)的發(fā)展、城市化進(jìn)程的加快以及人民生活水平的提高,居民家庭生活碳排放量不斷增加。相關(guān)研究表明,居民家庭和個(gè)人消費(fèi)行為的改變,有助于減少碳排放,促使碳排放結(jié)構(gòu)更加合理,家庭生活領(lǐng)域有巨大的減排潛力。分析碳排放影響因素,通過限制某個(gè)或某些因素,可以有效減少碳排放。本文利用國家統(tǒng)計(jì)數(shù)據(jù),評(píng)估了1995-2012年西北地區(qū)(陜西、甘肅、青海、寧夏、新疆)家庭碳排放的基本狀況,基于STIRPAT模型的擴(kuò)展模型,結(jié)合嶺回歸擬合,對(duì)西北地區(qū)家庭碳排放的影響因素進(jìn)行了實(shí)證研究。本文主要做了以下幾個(gè)方面的工作：(1)評(píng)估1995-2012年西北地區(qū)家庭生活碳排放的基本狀況。從家庭碳排放總量、人均家庭碳排放量、直接間接碳排放量、家庭碳排放結(jié)構(gòu)等角度入手對(duì)西北地區(qū)整體及五省之間的生活碳排放進(jìn)行了分析。結(jié)果顯示：西北地區(qū)家庭碳排放總量在1995-2012年間增加了2.82倍,人均家庭碳排放量增加了2.36倍；西北五省之間家庭碳排放總量的差距始終較大,但人均家庭碳排放的差距卻逐漸減�。婚g接碳排放在排放總量中所占比重持續(xù)上升,人均間接碳排放已遠(yuǎn)高于人均直接碳排放；家庭碳排放重點(diǎn)從煤炭排放轉(zhuǎn)移為電力和食品排放。(2)基于STIRPAT模型的擴(kuò)展模型,對(duì)1995-2012年西北地區(qū)家庭碳排放的影響因素進(jìn)行了實(shí)證研究。結(jié)果表明,1995-2012年西北地區(qū)家庭碳排放的各影響因素按其影響程度從大到小依次為：人均GDP(20.26%)、家庭碳排放強(qiáng)度(17.38%)、人均消費(fèi)支出(11.51%)、城鎮(zhèn)化率(10.75%)、家庭規(guī)模(-10.18%)、勞動(dòng)年齡人口比重(9.61%)、大專以上文化程度人口比重(9.43%)、人口總量(5.36%)。其中,家庭規(guī)模對(duì)家庭碳排放的影響是負(fù)向的。(3)基于STIRPAT模型的擴(kuò)展模型,對(duì)1995-2012年陜西、甘肅、青海、寧夏、新疆各省家庭碳排放的影響因素進(jìn)行了分析。結(jié)果發(fā)現(xiàn),人均GDP(20.62%)、家庭碳排放強(qiáng)度(17.35%)、人均消費(fèi)支出(12.23%)是影響陜西家庭碳排放的主要因素；人均GDP(18.22%)、家庭規(guī)模(-15.13%)、家庭碳排放強(qiáng)度(14.9%)是影響甘肅家庭碳排放的主要因素；家庭碳排放強(qiáng)度(18.47%)、城鎮(zhèn)化率(14.86%)、人均消費(fèi)支出(12.83%)是影響青海家庭碳排放的主要因素；人均GDP(17.06%)、人均消費(fèi)支出(12.92%)、勞動(dòng)年齡人口比重(12.55%)是影響寧夏家庭碳排放的主要因素；家庭碳排放強(qiáng)度(28.25%)、人均GDP(16.63%)、人均消費(fèi)支出(14.37%)是影響新疆家庭碳排放的主要因素。
[Abstract]:Global warming has become a serious environmental problem faced by human beings. At present, the international community has generally believed that greenhouse gases, especially CO2, are the main causes of global warming. With the development of economy and society, the acceleration of urbanization and the improvement of people's living standards, the carbon emissions from household life are increasing. Relevant studies have shown that the change of household and personal consumption behavior is helpful to reduce carbon emissions, promote a more reasonable structure of carbon emissions, and has great potential to reduce emissions in the field of household life. By analyzing the influencing factors of carbon emissions, carbon emissions can be effectively reduced by limiting one or some factors. Based on the national statistical data, this paper evaluates the basic situation of household carbon emissions in Northwest China from 1995 to 2012 (Shaanxi, Gansu, Qinghai, Ningxia, Xinjiang). Based on the extended model of STIRPAT model, combined with ridge regression fitting, This paper makes an empirical study on the influencing factors of household carbon emissions in Northwest China. The main work of this paper is as follows: (1) to evaluate the basic situation of carbon emissions from household life in Northwest China from 1995 to 2012. From the point of view of total household carbon emissions, per capita household carbon emissions, direct and indirect carbon emissions, household carbon emission structure and so on, this paper analyzes the domestic carbon emissions in Northwest China as a whole and among the five provinces. The results show that the total household carbon emissions in Northwest China increased by 2.82 times in 1995 / 2012, and the per capita household carbon emissions increased by 2.36 times. The gap of total household carbon emissions between the five provinces of Northwest China is always large, but the gap of per capita household carbon emissions is gradually decreasing. The proportion of indirect carbon emissions in the total emissions continues to rise, and the per capita indirect carbon emissions are much higher than the per capita direct carbon emissions. The focus of household carbon emissions from coal emissions to electricity and food emissions. (2) based on the extended model of STIRPAT model, this paper makes an empirical study on the influencing factors of household carbon emissions in Northwest China from 1995 to 2012. The results showed that the influencing factors of household carbon emissions in Northwest China from 1995 to 2012 were as follows: per capita GDP (20.26%), household carbon emission intensity (17.38%), per capita consumption expenditure (11.51%). Urbanization rate (10.75%), family size (- 10.18%), proportion of working-age population (9.61%), proportion of population with higher educational level (9.43%), total population (5.36%). Among them, the influence of household size on household carbon emissions is negative. (3) based on the extended model of STIRPAT model, the influencing factors of household carbon emissions in Shaanxi, Gansu, Qinghai, Ningxia and Xinjiang provinces from 1995 to 2012 are analyzed. The results showed that per capita GDP (20.62%), household carbon emission intensity (17.35%) and per capita consumption expenditure (12.23%) were the main factors affecting household carbon emissions in Shaanxi. Per capita GDP (18.22%), household size (- 15.13%) and household carbon emission intensity (14.9%) were the main factors affecting household carbon emissions in Gansu Province. The intensity of household carbon emissions (18.47%), urbanization rate (14.86%) and per capita consumption expenditure (12.83%) are the main factors affecting household carbon emissions in Qinghai. Per capita GDP (17.06%), per capita consumption expenditure (12.92%) and proportion of working-age population (12.55%) were the main factors affecting household carbon emissions in Ningxia. Household carbon emission intensity (28.25%), per capita GDP (16.63%) and per capita consumption expenditure (14.37%) are the main factors affecting household carbon emissions in Xinjiang.
