Numerical approach concerning endogenous determination of location in city

本研究旨在寻找城市形态的内生决定因素，建立城市空间经济系统模型，对一定技术条件（交通技术等）下的城市均衡土地利用模式进行理论分析。已经结束了具体分析了城市次中心同一大都市区内两个或两个以上集中选址或同一企业多点选址批准的同类企业的均衡竞租。在理论分析的基础上，以该投标租金函数为中心建立了一个数值模型，并在此基础上进行了计算机模拟分析，该模型关注城市交通、通讯等参数的变化对均衡城市形态的影响，并在此基础上对模型进行了改进，尝试将其应用于各种情况下的城市形态预备期 关于我们 分析和结果，特别是在二维空间中，对复杂空间相互作用下的均衡城市形态进行了分析，得出了独特的结论。此外，基于交通、通信技术等参数，分析了内生决定城市空间结构的决定因素，检验了均衡城市形态与理论模型要求的模拟结果的对应性，并重新加入了对数值模拟的一个基本问题--破碎系统的检验。此外，交通和先进的通信技术通过模型中参数的变化来思考，关注实际城市中交通和通信技术的先进性和变化，并基于城市空间结构的时间序列变化的出现，围绕参数的选择尝试模型的改进。结果，可以证实，它可以用经济主体的行为来解释城市地价结构，在二维空间中，由于各经济主体的相互作用，出现了线性相似配置的各种模式的均衡土地利用配置。少

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.
