项目摘要

In this research, it aimed to find for endogenous determination factors of the city configurations, a Spatial Economic System of the city was modeled, and a theoretical analysis of the equilibrium land use pattern of the city under a certain technological condition (communication technology etc.) was done. Concretely, the equilibrium bid rent of occurred with two or more concentrated locations in the same metropolitan area of secondary center of the city or the same kind of firms approved by the multi point locations of the same firm was analyzed. A numerical model was made based on the theoretical analysis that centered on this bid rent function, and it analyzed it by the computer simulation based on it. In that case, it paid attention to the change in the equilibrium city configuration according to the change in the parameters of the urban transportation and the communication.The model's enhancing was tried to apply it to the city pattern of various cases based on this preparatory an … More alysis and result, the equilibrium city configuration in a complex space interaction in especially two dimension-space was analyzed, and a unique conclusion was obtained. Moreover, the deciding factor of an endogenous determined space structure of the city was analyzed based on parameters of transportation and the communication technology, etc. The correspondence of the equilibrium city configuration and the simulation result of the request of the theoretic model was examined, and the examination of a fundamental problem of the numerical simulation that was the break-up system was added again. In addition, transport and the advanced communications technology thought the one by the change in the parameter in the model, paid attention to advancement and the change in an actual city in transport and the communication technology, and tried the model's improvement centering on the selection of the parameter based on the appearance of a time series change in the spatial structure of the city.As a result, it was able to be confirmed that it could explain the land price structure in the city by the behavior according to the economic agent, and the equilibrium land use configuration of the various patterns of the linear similar configurations appeared in two dimension space as a result of each economic agent's interaction.

本研究旨在寻找城市配置的内生决定因素，对城市空间经济系统进行建模，并对一定技术条件（通讯技术等）下城市的均衡土地利用格局进行理论分析。具体而言，对城市二级中心同一都市区内两个或两个以上集中地点或同一企业多点地点批准的同类企业发生的均衡投标租金进行了分析。根据理论建立了数值模型分析以竞租函数为中心，并在此基础上进行计算机模拟分析，关注均衡城市配置随城市交通和通讯参数的变化而变化。在此基础上，尝试将模型的增强应用到各种案例的城市格局中，分析了复杂空间交互尤其是二维空间中的均衡城市配置，得出了独特的结论：此外，还获得了内生决定空间的决定因素。基于交通、通讯技术等参数对城市结构进行了分析，检验了均衡城市结构与理论模型要求的模拟结果的对应关系，并检验了数值模拟的一个基本问题另外，通过模型中参数的变化来考虑交通和先进通信技术，关注实际城市中交通和通信技术的进步和变化。，并围绕参数的选择尝试了模型的改进基于城市空间结构的时间序列变化的出现，证实了它可以通过经济主体的行为来解释城市的土地价格结构，并且均衡由于各个经济主体的相互作用，二维空间中出现了线性相似配置的各种格局的土地利用配置。
