| Research Abstract |
Reconciling Spectral Graph Theory with Input-Output Analysis, this paper develops a method to detect groups of industries that are strongly connected through exchanges of energy inputs. This method developed was applied to automobile supply chain in Japan, and major clusters with high energy intensity in the automobile supply-chain, Motor vehicle parts and accessories cluster, Sheet glass and safety glass cluster, and Motor vehicle bodies cluster, were identified. I find that Mthe energy consumptions in the three clusters account for 74% of the total energy consumption associated with the automobile supply chain of Japan.
