摘要:建立了一种基于投入产出法的碳排放核算模型，对我国2020年造纸工业碳排放进行了核算和评估。结果显示，我国造纸工业具有一定碳排放影响力，直接碳排放强度在非传统高耗能制造业中位居第2，创造单位产值所产生的碳排放量相对较高；间接碳排放占比在非传统高耗能制造业中列倒数第2位，对电力供应业的碳排放拉动量最高，对化学工业和农林牧渔业的拉动系数明显高于其他行业；出口贸易中，越南的碳排放拉动影响力最显著。提出了应强化政策引导，优化产业布局，实施能源结构转型，重视中间投入的降碳，鼓励碳排放量低、附加值高的纸制品出口等多项举措。

Abstract:A carbon emission accounting model based on the input-output analyses was established to calculate and evaluate the carbon emissions of China’s paper industry in 2020. The results showed that China’s paper industry had a certain carbon emissions impact， direct carbon emissions intensity ranked the second among the non-traditional high energy-consuming manufacturing industry， with carbon emissions generated relatively high by creating unit output. Indirect carbon emissions were the second lowest among non-traditional high energy-consuming manufacturing industry， with the highest carbon emissions contribution to the electricity supply industry， followed with the chemical， agriculture， forestry， animal husbandry， fishery， and other industries. Among the export trade， Vietnam had the most significant carbon emission pulling influence. Several initiatives were proposed in this paper， such as strengthening policy guidance， optimizing industrial layout， implementing energy structure transformation， attaching importance to carbon reduction of intermediate inputs， and encouraging the export of paper products with low carbon emissions and high added value.
