The purpose of this study is to analyse the influences of information and communication technology (ICT) on the structural changes of Japanese energy sectors from 1985-2005. In this study, ICT is represented by two explanatory variables, namely: 1) computers, main parts and accessories; 2) telecommunications equipment. We employ a statistical tool in investigating the influences quantitatively, namely constrained multivariate regression (CMR) model. Likelihood ratio test (LRT) method is applied in order to test the statistical significance of estimators in the fitted model. In this study, we focus on: 1) coal mining, crude petroleum, and natural gas; 2) petroleum refinery products; 3) coal products sectors. We then conduct the deeper analysis, the microscopic analysis, for each analysed sector. The results show that the explanatory variables gave the significant influences on the structural changes of analysed sectors during the period of the analysis. Besides, the results also describe that, in microscopic investigation, ICT instruments had a strong influence on the relationship between analysed and other sectors during 1985-2005.
