GENERAL EQUILIBRIUM ANALYSIS OF URBAN SPATIAL STRUCTURE. THE PORT‐CITY MODEL RECONSIDERED*
构建了一个港口城市的一般均衡模型，采用柯布-道格拉斯函数，能产生四种土地利用模式，其中一种为就业郊区化提供了新解释，并证明了每种模式的存在性和唯一性。
ABSTRACT In this paper, I consider a general equilibrium urban spatial structure in the setting of a port city by adopting Cobb‐Douglas type functional forms for production and utility functions. Unlike previous port‐city models, this one can generate four land‐use patterns, that is, (1) monocentric, (2) completely integrated, (3) partially integrated (with integration at the center), and (4) partially integrated (with integration at the urban fringe) land‐use patterns, and the last pattern suggests a new explanation of suburbanization of employment. The existence and uniqueness of each land‐use pattern is proven in a simple constructive way.
