## 3 Results and Discussion
### Results  
A total of two analysis results will be presented, including one for the IHS sector and the other for the DHS sector. Furthermore, as explained above, all results will be derived from analysis that specifies the city gas supply or steam and hot water supply sector as exogenous, not endogenous. The results of analyzing the production-inducing effects of the IHS and DHS sectors through Equation (2) using the demand-driven model are shown in Table 2.  
For example, one dollar of production or investment in the two sectors induces 0.00220 and 0.01457 dollars of production in sector 7, \"Chemical products,\" respectively. The sums of production-inducing effects for the two sectors are computed to be 0.07293 and 0.38770. The self-induced effect is naturally one. Thus, the total production-inducing effects of one dollar of production or investment in the IHS and DHS sectors are about 1.073 and 1.388 dollars. Interestingly, the latter is greater than the former. The results of assessing the value-added creation effects of the two sectors on other sectors through Equation (3) are presented in Table 3. For instance, one dollar of production or investment in the two sectors produces 0.00198 and 0.01182 dollars of value-added in sector 26, \"Professional, scientific, and technical services,\" respectively. One dollar of production or investment in the IHS and DHS sectors produces a total of 0.03597 and 0.14736 dollars of value-added in other sectors, respectively. \begin{table}

Table 1: Sector classification adopted in this study. The value-added ratio of a sector is defined as the value-added of the sector over the total input of the sector and denoted as self-induced effect in Table 3. The value-added ratios of the two sectors are 0.19168 and 0.51060, respectively. Therefore, the total value-added creation effects are about 0.228 and 0.658, respectively. One dollar of production or investment in the DHS sector creates more value-added in the national economy than that in the IHS sector.
