Numerical approach concerning endogenous determination of location in city

本研究旨在寻找城市配置的内生决定因素，建立了城市空间经济系统模型，并对一定技术条件（通信技术等）下的城市均衡土地利用格局进行了理论分析。具体分析了在城市二级中心的同一都市圈内两个或两个以上集中地点或同一企业的多点地点批准的同类企业的均衡投标租金。在理论分析的基础上，以该标租函数为中心建立了数值模型，并在此基础上进行了计算机仿真分析。在这种情况下，根据城市交通和通信参数的变化，关注城市均衡配置的变化。在此基础上，对该模型进行了改进，并将其应用于不同情况下的城市格局。进一步的分析和结果表明，在复杂空间相互作用下，特别是在二维空间中，对城市均衡配置进行了分析，得到了独特的结论。基于交通、通信技术等参数，分析了城市内生确定空间结构的决定因素。对平衡城市形态与理论模型要求的模拟结果的一致性进行了检验，并再次对数值模拟中的一个基本问题即破碎系统进行了检验。此外，交通与先进通信技术通过模型中参数的变化来思考，关注实际城市交通与通信技术的先进性和变化，并根据城市空间结构中出现的时间序列变化，围绕参数的选取，尝试对模型进行改进。结果表明，以经济主体为主体的行为可以解释城市土地价格结构，线性相似配置的各种模式的均衡土地利用配置由于各经济主体的相互作用而出现在二维空间中。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.
