Regional Economic Integration with Global Infrastructure

我们开发了一个多区域增长模型，考虑了知识生产的外部性和区域间的互动（商务旅行和移民），以研究快速交通系统对区域生产分工和区域收入差距的影响。该模型模拟了城市系统经济发展的动态过程，包括知识积累过程和资本积累过程。知识交流活动基本上是非常耗时的，知识积累带来的高工资率可能会造成一个困难的局面：如果我们想要进一步扩展我们的知识，我们必须宝贵的时间。为了讨论上述关于知识积累与时间价值（或工资率）的两难问题，我们还通过引入时间维度对多区域增长模型进行了扩展。该模型可以为分析以不同速度和成本传播知识的几种全球网络的作用提供有力的工具，这似乎是亚洲经济和政治发展中最重要的问题之一。在张安增长模型中明确引入城市系统的经济地理学，考察高速交通系统对城市格局发展过程、城市系统中资本和知识的积累以及经济地理学演化的动态影响。高速运输服务，包括铁路和航空系统，对城市系统的经济地理的主要影响是，它们为城市经济提供了更多的机会，使知识处理劳动力之间能够在城市间面对面交流。强调运输系统的地理和质量因素的差异如何影响区域经济发展。该模型模拟了城市系统经济发展的动态过程。

We have developed a multi-regional growth model, considering externality of knowledge production and inter-regional interaction (business trips and migration) in order to investigate the impact of rapid transportation systems upon the regional division of production and regional disparities in incomes. The model simulates the dynamic processes of the economic development of city systems, including knowledge accumulation process, as capital accumulation. Knowledge exchange activities are basically very time consuming, and the resulting high wage rate as a result of knowledge accumulation may create a difficult situation : if we want to expand our knowledge further, we must precious time.We also extend the multi-regional growth model by introducing the time dimension in order to discuss the above dilemma about knowledge accumulation and time value (or wage rate). The model can provide a powerful tool for analyzing the roles of several kinds of worldwide networks conveying knowledge with different speed and cost, which seems to be one of the most important issues regarding economic and political development in Asia.In our model, the economic geography of city systems is explicitly introduced into Zhangian growth modeling to investigate the dynamic impacts of high-speed transportation systems upon the development processes of city patterns, the accumulation of capital and knowledge in city systems, and the evolution of the economic geography. The main effect of high-speed transportation services, including railway and airway systems, upon the economic geography of city systems is that they provide city economies with expanded opportunities of inter-city face-to-face communications among the knowledge-handling labor force.It is emphasized how differences in geographic and qualitative factors of transportation systems may affect regional economic development. The model simulates the dynamic processes of the economic development of city systems.
