The Study On Embodied Carbon Emissions And Its Influencing Factors In The Sino-Japanese Bilateral Trade

Since the21st century, China’s foreign import and export trade is developing rapidly. The large-scale international trade not only has created the huge economic output and employment opportunities for China, but also caused a large number of energy consumption, carbon emissions and environmental damage. The relationship and interaction between international trade and carbon emissions is increasingly attracting the attention of the international community. With the deepening of bilateral economic and trade relations, both sides have become very important trade partners to each other. At present, the carbon emissions amount of China doubles compared to a decade ago, and China has become the country with the largest carbon emissions in the world, while the carbon emissions of Japan is basically in a stable state. The research on whether the bilateral trade between Japan and China produces carbon emissions transfer has very important significance.Firstly, the author puts forward the concept of implicit carbon, and analyze the trade’s impact on the environment and international trade pollution liability. On the basis of relevant theories, according to the input-output table, the energy consumption statistics and the import and export data we use the input-output model to calculate the embodied carbon emissions and the difference between China and Japan bilateral trade from2002to2011. The results show that during2002-2011Sino-Japanese trade implied carbon emissions increase or decrease has the same trend with import and export trade change, with2009as the turning point firstly increases sharply decreases and rebound phenomenon. Net exports in China and Japan trade implied carbon emissions shows that China in the bilateral trade is a net exporter of embodied carbon emissions, and it also shows that Japan through bilateral trade transfers a part of the carbon emissions to China, which is not conducive to the realization of China’s carbon emissions reduction target.Then, by using structural decomposition analysis based on input-output model from the structure effect, technology effect, and scale affect three aspects of influence factors, this paper carries on decomposition analysis about sino-Japanese trade implicit carbon emissions. The results show that changes in implied carbon emissions, China exports to Japan mainly depend on the common role in the scale effect and technical effect, and the scale effect is the main factor to promote China’s implied carbon emissions growth in export trade. The effect of the structure has less effect, and technology effect is inhibitory factor to export implied carbon emissions growth. Embodied carbon emissions in the import of scale effect for each year is positive, the technical effect is negative, and structural effect is firstly negative and then positive. The scale effect has important impact on import trade Embodied Carbon emissions, which is same with the export situation. From the sector analysis, China’s exports to Japan industries implied coefficient of carbon emissions are higher than import industry. Finally, On the basis of empirical analysis results the paper puts forward relevant policy recommendations to reduce China’s implied carbon emissions.
