确保减碳的首要任务是定量测度化石能源消费碳排放的增量影响因素及其大小。为分析北京市1997-2007年的碳排放增量,本文构建了一个扩展的(调入、进口)竞争型经济-能源-碳排放投入产出模型,从整体特征、不同产业、工业行业3个方面,对1997-2007年北京能源消费的碳排放增量进行了结构分解。分析发现:经济规模增长要素(消费、投资、调出和出口等)是拉动碳排放增长的主导因素,能源强度变动效应却是碳减排的决定性因素;在规模扩张因素中,消费和调出超过投资和出口,是碳排放增长的主要贡献者;2002以来新一轮“高碳”特征的工业化导致CO2排量呈急增之势;产业结构调整、三产比重最大使得服务业成为碳排放增长的最大部门,但工业排放的增长却后来居上;碳增排的重点行业是高能耗业,而碳减排的却是能源工业;两时段各效应在不同产业、不同工业行业的影响方向和大小不一。
確保減碳的首要任務是定量測度化石能源消費碳排放的增量影響因素及其大小。為分析北京市1997-2007年的碳排放增量,本文構建瞭一箇擴展的(調入、進口)競爭型經濟-能源-碳排放投入產齣模型,從整體特徵、不同產業、工業行業3箇方麵,對1997-2007年北京能源消費的碳排放增量進行瞭結構分解。分析髮現:經濟規模增長要素(消費、投資、調齣和齣口等)是拉動碳排放增長的主導因素,能源彊度變動效應卻是碳減排的決定性因素;在規模擴張因素中,消費和調齣超過投資和齣口,是碳排放增長的主要貢獻者;2002以來新一輪“高碳”特徵的工業化導緻CO2排量呈急增之勢;產業結構調整、三產比重最大使得服務業成為碳排放增長的最大部門,但工業排放的增長卻後來居上;碳增排的重點行業是高能耗業,而碳減排的卻是能源工業;兩時段各效應在不同產業、不同工業行業的影響方嚮和大小不一。

The first task in ensuring a reduction in CO2 emissions is to quantitatively measure the factors and their effect size on increasing CO2 emissions due to fossil fuel consumption. An extension of the buying and import-noncompetition economy-energy-CO2 emission input-output model was designed to analyze CO2 emission increases for Beijing from 1997-2007. The increase in CO2 emissions because of energy consumption was broken down into nine kinds of effects including the change in energy consumption intensity and structure, and economic scale expansion. We found that the effect of economic scale expansion such as consumption investment, export and selling were the main factors increasing CO2 emissions. The effect of the change in energy consumption intensity was the dominant factor reducing CO2 emissions. CO2 emissions increased rapidly from 2002. The ifrst increase in carbon emissions was related to the service industry, adjustment in industrial structure and the priority given to tertiary industries. High energy consumption manufacturing was the industrial branch driving CO2 emissions; the main industry driving CO2 emission reductions was the energy industry. The new round of industrialization with ‘high carbon’ features meant that CO2 emissions increased rapidly from 2002-2007. The quantity and direction of the nine focal effects varied across industries and different industrial sectors.
