Table 4: Wage-inducing effects of steam and hot water supply and city gas supply sectors. a government-owned agency with public confidence. The IO table and the IO analysis, which are the data and the methodology adopted in this research, respectively, do not contain any political perspective. The research used data with public confidence and applied a methodology that was scientifically standardized without much controversy in the literature. Therefore, the authors think that the data and methodology do not diminish the value of the research, but rather enhance it. Third, the analysis in the paper may support the results and conclusions only partially. There can be a variety of factors to consider in order to choose between DHS and IHS. For example, there are factors such as cost, environmental impacts, consumer convenience and preference, governmental policy direction, and economic effects. The factors except for economic effects have been sufficiently analyzed for DHS and IHS. However, the economic effects have not been fully investigated and the government is in dire need of quantitative information about them.
