本文将调整成本下的储蓄和投资最优增长模型与具有Dixit-Stiglitz结构的现代部门空间CGE模型相结合，建立了一个空间动态CGE框架。由于动态均衡路径上产品多样性的增加，该模型属于半内生增长模型的范畴。我们克服了现有的多区域模型的困难，正确地近似无限地平线均衡采用理论上一致的终端条件。货物，要素，企业和家庭的位置的区别，并在模型中纳入贸易成本允许研究各种问题的区域和运输经济学。我们描述了模型校准和量身定制的求解算法。使用两个说明性的例子演示的功能。
This paper sets up a spatial dynamic CGE framework by combining the optimal growth model of saving and investment under adjustment costs and the spatial CGE model with Dixit–Stiglitz structure in the modern sector. Because of increasing product diversity on the dynamic equilibrium path, the model belongs to the category of semi-endogenous growth models. We overcome the difficulty of existing multiregional models to correctly approximate the infinite horizon equilibrium by employing a theoretically consistent terminal condition. The distinction of goods, factors, firms, and households by location, and the incorporation of trade costs in the model allow to study a variety of issues in regional and transport economics. We describe the model calibration and a tailor-made solution algorithm. The functionality is demonstrated using two illustrative examples.
