二氧化碳减排是否会在短时间内抑制减贫仍不清楚。运用扩展的线性支出系统模型和CO2排放核算方法，测算了湖北省脱贫和CO2减排的价值，并引入脱钩分析模型，对湖北省CO2排放与脱贫的关系进行了实证分析。结果表明，尽管湖北省贫困线已远远高于2美元/日，但贫困指数仍然很小。贫困人口数、贫困差距和贫困差距平方指数的最大值分别低于0.25、0.10和0.05，说明扶贫开发具有良好的现实基础。与此同时，该地区的CO2排放量和能源强度呈倒U型曲线，目前处于下降阶段，但CO2排放量却大幅增加。多期数据分析结果表明，CO2减排与减贫之间的脱钩关系已由“扩张负脱钩”转变为“弱脱钩”，表明二者之间存在脱钩关系。研究结果可为进一步厘清两者关系、安排政策实施方案提供参考。
Whether CO2 emission reduction will inhibit poverty alleviation in a short time still remains unclear. In this paper, the extended linear expenditure system model and the CO2 emission accounting method were applied to measure the values of the poverty alleviation as well as CO2 emission reduction, and then decoupling analysis model was introduced to identify the relationship between CO(2 )emissions and poverty alleviation within Hubei Province, a poverty-stricken area in China. The results show that the poverty indices all remain small although poverty line within Hubei Province is much higher than two dollars per day. Maximum values for head count, poverty gap, and squared poverty gap indices are all lower than 0.25, 0.10, and 0.05 respectively, implying that there are good realistic bases for poverty alleviation. At the same time, CO2 emission and energy intensities within this region are characterized by inverted U-shaped curves and are currently in a declining phase, but CO2 emissions have significantly increased. Results derived from multi-period data analysis show that the decoupling relationship have switched from 'expansive negative decoupling' to 'weak decoupling', indicating that there is a decoupling relationship between CO2 emission reduction and poverty alleviation. The data and results can be used to provide further references for clarifying the relationship between the two and arranging the plan of policy implementation.
