The dynamics of the total outputs of Japanese information and communication technology sectors: A further study

[摘要] The purpose of this study is to continue the previous studies which discussed the impacts of the changes of final demands on the total outputs of the Information and Communication Technology (ICT) sectors of the specific country. More specifically, this study aims to conduct a deeper analysis regarding these impacts. This study focuses on the case of Japan. This study employs a demand-pull Input-Output (IO) quantity model, one of the calculation tools in the IO analysis, as an analysis instrument. Two conditions are included in calculations and analysis parts, namely (1) "whole sector change", and (2) "pure change". An initial period in this study is 2005. The results show that, in both conditions, the discussed sectors have similar patterns, namely these industries receive the positive impacts from scenarios 1, 3, and 4 while the opposite impacts are obtained from scenario 2. This negative impact also appeared in the previous studies. The results also expose that, in both conditions, the biggest positive impacts for analyzed sectors are given by scenario 4, the modification of the consumption expenditures of the private. Compared with the previous studies, these are new findings.
