近年来，国际贸易对碳排放的影响成为了重要的问题，但是非洲受到的关注远远少于其他国家。本研究使用投入产出模型从价值链视角分析了1995-2015年中非贸易对中国、非洲以及其他国家二氧化碳排放和增加值创造的影响，包括49个国家（地区）163个部门。

研究结果表明，1995-2015年，中国和非洲的二氧化碳排放均有增加，中国的二氧化碳排放量不仅远高于非洲，增长速度也明显更快，1995年中国二氧化碳排放量为30亿吨，非洲仅仅2亿吨，2015年中国二氧化碳排放量接近100亿吨，而非洲仅8亿吨。中国和非洲二氧化碳排放的主要来源都是从生产到消费完全发生在本地的产业链。在中国和非洲的双边贸易中，非洲主要出口中间产品，而中国的最终产品所占比重较高。中国和非洲碳排放和增加值创造的不同部门结构显示了中国的制造业最为突出而非洲以采矿业和农业为主。一些部门（例如，电力热力和水的供应）排放了大量的二氧化碳却只创造了很少的增加值，但一些部门二氧化碳排放量低而创造增加值的能力较高。中国和非洲之间的双边贸易也影响了其他国家（例如，美国、印度、日本、德国和俄罗斯）的碳排放，中国到非洲的出口贸易给美国、日本和韩国带来了大量的碳排放（30-56万吨）和增加值（5-11亿欧元），非洲到中国的出口则给美国、印度以及部分欧洲国家带来了较多碳排放（15-31万吨）和增加值（2-3亿欧元）。

The impact of trade on carbon dioxide emissions has become the main focus in recent years but Africa has received little attention as compared to other countries. This study analyses the impact of China-Africa trade on carbon dioxide emissions and value-added creation in China, Africa and other countries. Multi- regional Input-output analysis and data of 49 countries with 162 sectors from 1995 to 2015 were used in this study.

The results indicate that there is an increase of carbon dioxide emissions from 1995 to 2015 for both China and Africa; China's carbon dioxide emissions were not only significantly higher than those of Africa, but also increased more. Carbon dioxide emissions for China was 3 billion tonnes in 1995 while that of Africa was only 0.2 billion tonne), and in 2015 China had almost 10 billion tonnes of Carbon dioxide emissions while Africa had only 0.8 billion tonne. The most important sources of carbon dioxide emissions and value added creation in China and Africa are complete domestic production and consumption. For bilateral trade between China and Africa, Africa mainly exports intermediate products, while China's final products account for a higher proportion. The different sectoral structures of China’s and Africa’s carbon emissions and value added creation reflected that China had the stronger manufacturing industry while the mining and agriculture occupied higher proportion in industrial system of Africa. Meanwhile, it has also been found that some sectors emit high amount of carbon dioxide but they have very little value added creation (such as electricity, heat and water supply) while others have very little carbon dioxide emissions but they have high value added creation. Bilateral trade between China and Africa also had an important impact on the carbon dioxide emissions and value added creation of other countries such as the United States, India, Japan, Germany, and Russia. The United States, Japan and South Korea generated greatest carbon dioxide emission (300 – 561 kilo tonnes) and value added (560 – 1087 Million EUR) in the China's export to Africa, while United States of America, India and some European countries were affected most by African exports to China Carbon dioxide emission (150 - 306 kilo tonnes) and value added (190 -309 Million EUR).

This paper constructs an analysis framework for the impact of bilateral trade on the carbon emissions and value-added creation of trading countries and other countries. The results can provide support for climate policy adjustments related to China-Africa trade.
