温室効果ガス排出規制の地域間CGE分析

Although many CGE models have already been developed for analyzing the climate policy in Japan, most of them only investigate national level impacts. However, impacts of emissions regulations are likely to vary considerably by region because there are large regional differences in household expenditure pattern and industry structure. To investigate regional impacts of greenhouse gas (GHG) emissions regulations in Japan, we construct a new multi-regional CGE model with 9 regions in Japan and estimate regional GHG emissions. We analyze impacts of 10% reduction of GHG on regional GDP, welfare and production. Our simulation shows that regions with the higher share of energy-intensive industries and thermal power generation incur the larger loss in GDP.
