| Research Abstract |
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.
