Transportaton and eect on economic growth based on optmal control theory

In order to study the relationship between transportation and economic growth from the macro, in this paper the concepts of impact factor and conversion efficiency of transportation level are introduced. Based on the analysis of New-Classical Growth Theory, an economic growth model with transportation factors IS set up. Through analysis of the model the action mechanism and influence path of transportation on regional economic growth is revealed. And the results indicate that the positive equilibrium economic growth rate exists when impact factor transportation level satisfies certain condition. And economic growth is inversely related to impact factor of transportation level. This model has some practical values for transportation planning and the coordinated development of regional economic and transportation.
