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，通过对城市空间经济系统的建模，对一定技术条件(通信技术等)下的城市土地均衡利用模式进行理论分析。已经完成了。具体地说，分析了城市副中心同一大都市区内两个或两个以上集中地点发生的均衡投标租金，或同一公司多点选址批准的同类公司的均衡投标租金。以该投标租金函数为核心，在理论分析的基础上建立了数值模型，并在此基础上进行了计算机仿真分析。在这种情况下，考虑了均衡城市形态随城市交通和交通参数的变化而发生的变化，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格局通过进一步的分析和结果，对复杂空间特别是二维空间相互作用下的均衡城市形态进行了分析，得出了一个独特的结论。从交通参数、通信技术等方面分析了内生决定城市空间结构的决定因素，考察了均衡城市形态与理论模型要求的模拟结果的一致性，并重新增加了对数值模拟的一个基本问题--解体系统的考察。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模型，关注交通和通信技术在实际城市中的进步和变化，并尝试以城市空间结构中出现的时间序列变化为基础的参数选择为中心进行模型的改进，从而能够证实它可以根据经济主体的行为来解释城市的地价结构，由于各个经济主体的相互作用，线性相似配置的各种模式在二维空间中出现了均衡的土地利用结构。较少

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.
