Simulation analysis of the living-leisure space and cyberspace economy

建立了单城市经济的一般均衡模型，建立了信息、交通拥堵、外部规模经济和集聚效应的一般均衡模型，模拟分析了虚拟商品、虚拟企业和现有实体城市基础设施之间关系的重要作用，强调了网络空间与物理空间的分离；对信息和交通网络以及外部规模经济和集聚经济的多城市系统进行了数值模拟分析。将虚拟网络空间定义为一种新的城市基础设施，分析了网络空间与物理空间之间的相互关系，考虑了城市之间常见的商品流和信息流；分析了目前全球范围内发展的电信系统的最优结构，特别是考虑两者之间的可替代性的地面和卫星通信系统的最佳频段分配；通过多城市非线性系统的数值模拟，分析了住房、交通和农业的土地利用；针对IT产业集聚区的特点，对信息和电信政策进行了综述。

The general equilibrium model of a single city economy was presented in which information, traffic congestion, and external economies of scale and agglomeration are formulated in order to make a simulation analysis of an important role of the relation between virtual goods, virtual firms, and existing physical urban infrastructures focusing on the separation of the cyberspace from the physical one.We also made a numerical simulation analysis of the system of plural cities in which the information and transportation network and the external economies of scale and agglomeration. Interrelation between the cyberspace and physical space was analysed taking account of usual commodity flow and information traffic flow between the cities by specifying endogenous the virtual cyberspace as a new urban infrastructure.The optimal structure of telecommunication systems, which is now developed with a global scale, and especially the optimal frequency band assignment of the surface and satellite communication system was analysed taking account of the substitutability between the two.Land use of housing, transportation, and agriculture was analysed by a numerical simulation of non-linear system of plural cities.Information and telecommunication policies were surveyed focusing on characteristics of the agglomerated area of IT industries.
