Table 2: Production-inducing effects of steam and hot water supply and city gas supply sectors. The results of computing the wage-inducing effects of the IHS and DHS sectors through Equation (4) are summarized in Table 4. For example, one dollar of production or investment in the two sectors induces 0.00269 and 0.00385 dollars of wage in sector 27, \"Business support services,\" respectively. One dollar of production or investment in the IHS and DHS sectors produces a total of 0.01525 and 0.04850 dollars of wages in other sectors, respectively. It also leads to 0.03598 and 0.05975 dollars of self-induced wages, respectively. Thus, it causes about 0.051 and 0.108 dollars of wages in the national economy overall, respectively. The wage-inducing effect of one dollar of production or investment in the DHS sector is bigger than that in the IHS sector.
