摘要: 本文基于2002-2017年中国投入产出表(延长表),运用非竞争型投入产出模型测算出我 国各产业部门的隐含碳排放,并将其引入到碳排放效率测算模型当中,再利用三阶段DEA模型将外部 环境和随机干扰因素剔除,从而得到更加准确客观的各产业部门隐含碳排放效率水平。实证结果表明: 目前我国整体产业部门隐含碳排放效率还处于较低水平,且各产业部门之间的隐含碳排放效率水平差 异显著。根据第三阶段各产业部门隐含碳排放效率历年均值的聚类分析可知,农业、石油和天然气开采业、批发零售及餐饮业及其他服务业处于高等效率水平,电气机械及器材制造业、通信设备和计算机及 其他电子设备制造业、电力热力的生产和供应业、燃气的生产和供应业以及煤炭采选业等处于中等效率 水平,而资源依赖、创新能力较差的纺织服装鞋帽皮革羽绒及其制品业、木材加工及家具制造业等,水的生产和供应业、建筑业、交通运输、仓储及邮政业处于低等效率水平。外部环境对各产业部门隐含碳排 放效率影响显著,影响方式主要有三种,即“交叉型”“重合型”和“平行型”。 “交叉型”产业部门主要以制造业为主,外部环境对其影响先提升后抑制;“重合型”产业部门主要以第一、三产业为主,外部环境 对其影响甚微;“平行型”产业部门主要以资源型行业为主,外部环境对其影响就具体行业而定。

Abstract: Based on China’ s Input-output Tables ( extended) 2002 - 2017, this paper first applies the non-competitive input-output model to calculate the carbon emissions embodied in each industrial sector in China, introduces them into the carbon emissions efficiency model, and then uses the three-stage DEA model to eliminate the external environment and random interference factors, so as to obtain a more accurate and objective carbon emissions efficiency level embodied in various industrial sectors. The results show that the carbon emissions efficiency embodied in China’ s overall industrial sector is relatively low, and the levels of efficiency between industrial sectors are significantly different. The clustering analysis of the yearly average efficiency of carbon emissions embodied in each industrial sector in the third stage indicates that agriculture, oil and gas, wholesale and retail, catering and other services have high efficiency, electrical machinery and equipment manufacturing, communications equipment and computer and other electronic equipment manufacturing, electric power and heat production and supply, gas production and supply, coal mining have medium efficiency, while resource-dependent and less innovative industries such as textile, clothing, footwear, hats, leather, feather and their products, wood processing and furniture manufacturing, water production and supply, construction, transportation, storage and postal industries have low efficiency. The external environment has a significant impact on the carbon emissions efficiency embodied in various industrial sectors in three ways, namely “ cross type”, “ overlap type” and “ parallel type”. The “ cross type” is mainly in the manufacturing industry, the impact of external environment on its carbon emissions efficiency firstly improving and then suppressing. The “overlap type” is mainly in the agriculture and services industry, and the external environment has little impact on their carbon emissions efficiency. “Parallel type ” is mainly in resource-based industry, and the impact of the external environment on its carbon emissions efficiency depends on specific industries.
