SPATIAL ECONOMIC INTERDEPENDENCE IN AN URBAN HIERARCHY SYSTEM
构建了一个模型，研究中心地与其腹地之间的经济互动，允许城市等级体系中的产业间联系和向上贸易流，发现经济基础乘数通常随城市规模增大，但有时可能小于低等级城市。
ABSTRACT. This paper develops a model to examine the economic interaction between central places and their hinterlands. The model allows interindustry linkages and upward trade flows in an urban hierarchy system. Trade balance equilibrium between hierarchical levels is established by direct mutual interlevel trade, rather than by indirect trade via the rural sector. The economic base multipliers generally increase with city size but occasionally they could be smaller than those of lower places. A continuous urban hierarchy is formed due to their relative location within the system, not to unspecified randomness.
