贸易创造了一种具体化的二氧化碳排放在地区之间转移的机制，导致总排放量的扭曲。作为世界第二大经济体，中国的贸易规模很大，这就导致了体现型二氧化碳排放转移的严重问题。本文从省域角度分析了中国在国际贸易和省际贸易中所体现的二氧化碳排放特征。多区域投入产出模型用于从地理和部门层面明确各省的二氧化碳排放量，包括30个省和28个部门。应用了两个计算原则(生产核算原则和消费核算原则，Munks Gaard和Pedersen，2001)。结果表明，在国际贸易中，东部地区在中国体现的二氧化碳排放量中占有较大比例。作为有形二氧化碳排放净出口国和进口国的部门分别属于劳动密集型和能源密集型行业。对于省际贸易，体现二氧化碳排放量的净转移是从东部地区向中部地区，能源密集型行业是主要贡献者。东部地区是二氧化碳直接排放量最大的地区，在二氧化碳减排中发挥着重要作用。中西部地区需要扶持政策，避免高排放产业转移。(C)2011爱思唯尔有限公司。保留所有权利。
Trades create a mechanism of embodied CO2 emissions transfer among regions, causing distortion on the total emissions. As the world's second largest economy, China has a large scale of trade, which results in the serious problem of embodied CO2 emissions transfer. This paper analyzes the characteristics of China's CO2 emissions embodied in international and interprovincial trade from the provincial perspective. The multi-regional Input-Output Model is used to clarify provincial CO2 emissions from geographical and sectoral dimensions, including 30 provinces and 28 sectors. Two calculating principles (production accounting principle and consumption accounting principle, Munksgaard and Pedersen, 2001) are applied. The results show that for international trade, the eastern area accounts for a large proportion in China's embodied CO2 emissions. The sectors as net exporters and importers of embodied CO2 emissions belong to labor-intensive and energy-intensive industries, respectively. For interprovincial trade, the net transfer of embodied CO2 emissions is from the eastern area to the central area, and energy-intensive industries are the main contributors. With the largest amount of direct CO2 emissions, the eastern area plays an important role in CO2 emissions reduction. The central and western areas need supportive policies to avoid the transfer of industries with high emissions. (C) 2011 Elsevier Ltd. All rights reserved.
