Development of Spatial General Equilibrium Model for Economic Evaluation of Adaptation Policy and Biodiversity Change by Global Warming

为了评估气候变化对生物多样性服务变化的经济影响，本研究建立了符合经济模型和物理模型时空分辨率的空间可计算一般平衡模型，并通过数值实验分析了土地利用变化情景。将土地利用作为生产要素之一，将生物多样性变化设定为土地利用变化，可以捕获以网格单位计算的土地利用变化的经济影响。

To evaluate the economic impacts of change in biodiversity services by climate change, the purposes of this study are to develop a spatial computable general equilibrium model consistent with temporal-spatial resolutions between economic model and physical model, and to analyze land-use change scenarios by numerical experiments. By taking into account the land use as one of the production factors and setting the biodiversity change as land-use change, this study shows that the economic impacts of land use changes calculated in mesh unit can be captured.
