| 摘 要： | 基于多区域投入产出模型，以上海市为例全面了探讨城市地区的贸易隐含碳排放，并在此基础上深入分析贸易对城市产业与最终消费部门碳排放及其减排责任的影响。研究发现：2007年上海市各部门的国内贸易隐含碳总量为68.97 MtCO2，约占当年上海碳排放总量的42.31%；而其国际贸易隐含碳量的上限值和下限值分别为44.39和25.93 MtCO2，分别约占当年上海碳排放总量的27.23%和15.91%。与此同时，2007年上海市最终消费的国内贸易隐含碳总量为13.63 MtCO2，约占当年上海碳排放总量的8.36%；而其国际贸易隐含碳量的上限值和下限值分别为4.58和0.59 MtCO2，分别约占当年上海碳排放总量的2.81%和0.36%。此外，上海市的国际与国内贸易隐含碳流入量和流出量等均存在显著的部门差异。而在国内贸易中上海市贸易隐含碳的流入与流出上，流入上海的贸易隐含碳排名前五的地区分别是河北、浙江、湖北、江苏和河南，接受流出上海的贸易隐含碳量排名前五的地区分别是浙江、广东、江苏、河北和安徽。

| Abstract: | In order to provide an important theoretical basis for proper policymaking to allocate the responsibility for CO2 emission reduction at the city scale and make targeted reduction policy for urban economy, Shanghai city was used as a representative case to calculate the embodiment of local CO2 emission based on the Chinese MRIO tables of 2007. Two CO2 emission accounting approaches (production accounting principle and consumption accounting principle) were also applied, and the sources and flows of the embodied CO2 emission in domestic import by and export from Shanghai in 2007 were discussed. One finding from this study was that Shanghai’s CO2 emission embodied in domestic trade was 82.60 million tons, which accounted for approximately 50.67% of Shanghai’s CO2 emission in 2007. The lower limit and the upper limit of Shanghai’s CO2 emission embodied in international trade were 48.97 and 26.52 million tons, which accounted for approximately 30.04% and 16.27% of Shanghai’s CO2 emission in 2007, respectively. Moreover, the difference between the lower limit and the upper limit of Shanghai’s EEI was very large, indicating that Shanghai had a great potential in realizing energy-saving and emission reduction. In addition, Embodied CO2 emission in total output and final consumption differed widely between the 30 industrial sectors in Shanghai. Notably, the higher the net output of CO2 emission embodied in various sectors in international trade was, the less obviously Shanghai’s CO2 emission was affected by a production-based approach. Another important finding was that the top five contributors in terms of CO2 emission embodied in domestic import by Shanghai were Hebei, Zhejiang, Hubei, Jiangsu and Henan. Additionally, further calculation suggested that the CO2 emission embodied in domestic import by Shanghai from these five regions accounted for approximately 45.74% of the total and 17.05% of Shanghai’s CO2 emission respectively, suggesting that these regions provided a strong support for Shanghai’ economic growth through trade. The top five receivers in terms of CO2 emission embodied in domestic export from Shanghai were Zhejiang, Guangdong, Jiangsu, Hebei and Anhui. Additionally, further calculation suggested that the CO2 emission embodied in exports from Shanghai in domestic trade to these five regions made up 50.04% of the total and 6.71% of Shanghai’s CO2 emission in 2007, respectively, suggesting that the impact of CO2 emission embodied in export trade from Shanghai on these regions’ responsibilities for CO2 emission reduction may be greater than on the other regions of China. |
