| Research Abstract |
This study proposes clustering techniques for finding groups of industries with relatively large CO2 emissions through industrial relations, that is CO2 cluster. According to our empirical results, the optimal number of industry clusters from the automobile supply-chain network is 19, and 4 industry clusters are playing a key role in CO2 emission reduction. In addition, this study attempted to detect CO2 clusters from the industrial structures of Japan, U.S.A., and China by applying the environmentally-extended Asian input-output table to the clustering technique. The results show that the Japanese economy, US economy, and Chinese economy include 5 clusters, 11 clusters, and 7 clusters, respectively and reveal a variety of cluster structures in their economies.
