For a continuous core-periphery model, we construct a core-periphery model with n regions for each \(n\ge 2\). Assuming that the known functions of the core-periphery model with n regions and the diameters of n regions converge to the known functions of the continuous core-periphery model and 0 respectively as the number n tends to infinity, this paper proves approximate relations between the continuous core-periphery model and core-periphery models with a large number of small regions when the models are in short-run equilibrium.

用大量小区域的核心-外围模型逼近连续的核心-外围模型

对于连续的核心-外围模型，我们构建了一个核心-外围模型，每个\(n\ge 2\)都有n 个区域。假设随着n趋于无穷大， n个区域的核心-外围模型的已知函数和n个区域的直径分别收敛于连续核心-外围模型的已知函数和0 ，本文证明了当模型处于短期均衡时，连续的核心-外围模型和具有大量小区域的核心-外围模型。
