Equilibrium Market Areas in The Perfectly Competitive Spatial Market : Losch Revisited (1)

A．レッシュは，空間経済学的主要命題の一つである「蜂の巣状均衡市場領域定理」を，凡そ60年前に導出した。本稿は，「同定理の再考・再評価をあらためて試み，併せて同定理周辺部の未墾概念に多少の発展的考察を加える作業」の第一段階で得られた成果を纏めたものであり，一次元空間及び二次元空間に於ける家計の離散的分布を仮定した場合に考えられる「円形均衡市場領域の境界線形成過程」を，テーマの中心に据えて論ずる。The theorem of the”hexagonal equilibrium market area in the perfectly competitive spatial market”was constructed by A．L6sch around sixty years ago． The present paper is the first outcome of the study in which the authors have tried to（1）review and revaluate the L6sch’s theorem and（2）explore what has been left behind the derivation of his seminal classic theorem， for the purpose of shedding a slight new light upon the basic characteristics of the L6schian paradigm． Our first outcome discussed in this paper， focuses upon the dynamic process in which the boundaries of market areas are delineated towards the equilibrium situation in the perfectly competitive spatial market
