摘　　要：文章通过分解模型从横向和纵向两个方面分析影响碳排放强度变化的因素。研究表明,江苏省碳排放强度变动由行业碳排放强度和行业产出份额共同作用。相对于行业产出份额,行业碳排放强度对整个社会碳排放强度变动影响更大。而工业行业对整个社会碳排放强度贡献较大,工业部门内部结构变化对碳排放强度变化有较大影响。因此,江苏省碳排放强度研究应该重点放在行业碳排放强度的变化,尤其是研究工业行业碳排放强度的变化上以及工业结构的调整上。This article attempts to use the decompositions model analyzes the factors that influence carbon dioxide emissions intensity change from crosswise and the longitudinal aspects. The research shows that carbon dioxide emissions intensity change caused by the profession carbon emissions intensity and the profession share. In proportion to the share in the profession, the carbon dioxide emissions intensity is bigger to the entire social carbon emissions intensity change. And the industry profession has a big contribution to the entire social carbon emissions intensity. The internal structural change of industry sector also has a big influence to the carbon emissions intensity change. Therefore, the research of carbon dioxide emissions intensity should place an emphasis on the profession carbon dioxide emissions intensity change, particularly profession carbon dioxide emissions intensity change of industry as well as the industry structure adjustment.
