摘　　要：以调整后的2007年中国投入产出表为基础对铁路运输业的直接、完全碳排放量进行了计算,提出采用碳排放弹性系数对计算结果进行定量评价,然后利用投入产出法的影响力和感应度系数将铁路运输业碳排放对其他行业部门和总碳的影响程度进行量化.结果表明,铁路运输业碳排放中以最终产品的碳排放为主;铁路运输业碳排放对其他部门推动作用小,对总碳排放拉动作用低于其他部门;同时验证了控制铁路运输业减排是发展低碳交通的关键.Based on the adjusted Input-Output table of China,the direct and full carbon emission of railway transportation are calculated. Elastic coefficient is put forward to quantify the influential extent of railway carbon emission to other industries and total carbon emission. Then the results of influence and response coefficient demonstrate railway＇s significance in low carbon transportation. The result shows that the end-product＇s carbon emission takes the main part in railway transportation＇s emission which has little effect on pushing other departments＇ emission and has lower effect on increasing the total emission than other departments. The reduction of railway transportation is the key to low-carbon transportation.
