GENERAL EQUILIBRIUM ANALYSIS OF URBAN SPATIAL STRUCTURE. THE PORT‐CITY MODEL RECONSIDERED *

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.
