Structural characteristics and evolution of the “international trade-carbon emissions” network in equipment manufacturing industry: international evidence in the perspective of global value chains

The objective of this paper is to analyze structural characteristics and the evolution of “international trade-carbon emissions” network in the equipment manufacturing industry. To do so, we construct four kinds of networks, namely export trade network (E network), export implied carbon emission network (EC network), foreign value-added network (FVA network), and foreign value-added implied carbon emission network (FVAC network) for the said industry. The data obtained from world-input-output table and social network analysis method was used for empirical analysis. The results indicate that (1) the four types of networks show a trend of denseness, which also has the characteristics of trade clustering effect and small-world network. As the equipment manufacturing industry in various countries is increasingly embedded in the global value chain, the value chain is extended globally, which leads to the complexity of the international carbon transfer network. (2) The four types of networks’ pattern are basically stable. Germany plays an important intermediary role. Whereas China is deeply involved in the division of global value chain and has achieved the shift from the edge to the core in all four types of networks, but there is still a big gap compared with Germany. (3) The E network and EC network have the obvious core-edge feature, and the two kinds of networks can be divided into developed countries block represented by Germany, Japan, the USA; developing countries block represented by China and India; and European Union block represented by Spain and France. The developing world receives carbon emission transfer from the developed world. Finally, (4) the division of FVA network and FVAC network segment shows that the global value chain under the current international division of labor is characterized by multi-regionalization. Therefore, actively embedding in the regional value chain has become an important way for China’s equipment manufacturing industry to upgrade to low carbon.
