城市经济系统的结构模型及参数估计

Structural Models and Its Parameter Estimation of Urban Economic System

城市经济系统是由多个经济部门以某种方式和强度耦合而形成的,各部门间不同的偶合形式和耦合强度决定着城市经济系统的不同结构和功能。每一经济部门的生存和发展受城市经济系统内其它部门和系统环境的影响,市场需求的有限性、饱和性导致了微观部门之间的相互竞争;单个部门功能的有限性,使得它们需要相互依赖,出现了互惠增长的局面;而各个部门的素质,放大功能(劳动生产率。

Based on the different couple relations between dcparmcnts, this paper establishes the structural models of urban economic system. In accordance with the nonlinear characteristics of the models, a new recursive parameter estimation method is given and studied. Through analysis, a lot of useful conclusions arc obtained for the first time by authors.
