The introduction of the new biomass industry exerts influences that change the interactions among economic sectors by drawing the resources for generating electricity, pricing alterations from the existing market and competitively selling electricity to the power grid. These influences should be described and identified to ensure the benefits to the local economy. In this article, we deem to test the potential of hybrid I-O analysis to analyze the economic impacts and address the change in characteristics of the economic impacts of the biomass power plant. The resource utilization data from the existing biomass power plant located in Kochi Prefecture (Japan) is collected and then analyzed by a hybrid input-output (I-O) analysis. We found that (1) the use of cutoff function could determine the new economy’s structure included the biomass power plant where the allocation of resource in the economy is changed according to the consumption and production of the biomass power plant, (2) The power plant increases the total production of Kochi prefecture’s economy, and this benefit overthrows the negative effect of the loss of resource demand of the existing economic sectors. The use of the hybrid I-O to forecast the economic impacts on the local economy could enhance the decision made by the policymaker.

新的生物质能产业的引入通过改变发电资源，改变现有市场的价格以及向电网竞争性出售电力的方式，改变了经济部门之间的相互作用。应该描述并确定这些影响，以确保为当地经济带来收益。在本文中，我们认为将测试混合IO分析的潜力，以分析经济影响并解决生物质电厂经济影响特征的变化。收集位于日本高知县的现有生物质发电厂的资源利用数据，然后通过混合投入-产出（IO）分析进行分析。我们发现（1）截断函数的使用可以确定包括生物质发电厂在内的新经济体的结构，其中生物质发电厂根据生物质发电厂的消耗和生产来改变经济中的资源分配，（2）该发电厂增加了高知县经济的总产量，这种好处推翻了现有经济部门资源需求损失的负面影响。使用混合IO预测对当地经济的经济影响可以增强决策者的决策。这种好处推翻了现有经济部门资源需求损失的负面影响。使用混合IO预测对当地经济的经济影响可以增强决策者的决策。这种好处推翻了现有经济部门资源需求损失的负面影响。使用混合IO预测对当地经济的经济影响可以增强决策者的决策。
