从新经济地理学、中心地理论和分岔理论等多学科视角研究了二维经济空间中经济模型集聚模式的自组织问题。从理论上预测了核-外围模型在均匀空间中出现各种大小的六边形分布。通过对特定核心-外围模型运输成本的比较静态分析，证明了六方分布作为稳定均衡的存在性。这些分布是中心位置理论所设想的，也是克鲁格曼（1996）在二维核心-外围模型中推断出来的。(C) 2013 Elsevier B.V.版权所有
Self-organization of agglomeration patterns for economic models in a two-dimensional economic space is studied from a multi-disciplinary viewpoint of new economic geography, central place theory, and bifurcation theory. Emergence of hexagonal distributions of various sizes in a homogeneous space is predicted theoretically for core-periphery models. The existence of hexagonal distributions as stable equilibria is demonstrated by a comparative static analysis with respect to transport costs for specific core-periphery models. These distributions are the ones envisaged by central place theory and also inferred to emerge by Krugman (1996) for a core-periphery model in two dimensions. (C) 2013 Elsevier B.V.
