解耦分析能够揭示经济增长与环境压力之间的联系。然而，传统的研究大多集中在基于生产的解耦分析上，而忽略了供应链为满足最终消费者而产生的压力。通过一个综合投入产出分析、分解方法和Tapio指数的综合框架，本研究可以被认为是首次尝试同时从生产基础和消费基础的角度来探讨中国是否努力将经济增长与二氧化碳排放脱钩。研究发现：(1)2002-2015年，中国的二氧化碳排放量增长了约1.6倍，其中电力和热力的生产和供应以及建筑分别对生产型排放（PBE）和消费型排放（CBE）贡献最大；(2)四分之三的行业在PBE和CBE两种视角下均表现为弱脱钩或强脱钩，纺织行业是唯一在两种视角下均表现为强脱钩的行业；(3)在PBE视角下，所有行业都在努力实现经济增长与二氧化碳排放的脱钩，而在CBE视角下，部分行业未能实现经济增长与二氧化碳排放的脱钩。总体而言，在研究期间，PBE的脱钩状况优于CBE。我们的研究结果能够为生产者和最终消费者之间更充分、合理地分配解耦责任提供有针对性和有效的参考。
Decoupling analysis is able to reveal the linkage between economic growth and environmental pressure. However, traditional studies mostly concentrate on production-based decoupling analysis and ignore the pressure emerging from supply chains to satisfy the final consumption. Through a comprehensive framework integrating input–output analysis, decomposition methods, and the Tapio index, this work may be considered the first attempt to explore whether China made efforts to decouple economic growth from CO2 emissions from production-based and consumption-based perspectives simultaneously. We found that (1) CO2 emissions in China expanded by around 1.6-fold during 2002–2015, of which Production and supply of electricity and heat and Construction contributed most to the production-based emissions (PBE) and consumption-based emissions (CBE), respectively; (2) Three-quarters of sectors presented weak decoupling or strong decoupling under both PBE and CBE perspectives, and Textile was the only sector achieving strong decoupling under both perspectives; (3) All sectors have made efforts to decouple economic growth from CO2 emissions under PBE perspective, while several sectors failed under CBE perspective. Overall, the decoupling status for PBE was better than that for CBE during the study period. Our results are able to provide targeted and effective references for allocating decoupling responsibilities between producers and final consumers more adequately and reasonably.
