| Research Abstract |
We have intended to construct a dynamic interregional input-output programming model in order to measure social economic effects of the Asian Expressway Network on China and derive its investment criterion. That is, the accelerating-system for yielding agglomeration-effects is built into the model, by which the dynamic process of 'takeoff' of China has been derived.
It is not too much to say that we can recognize the Asian Expressway Network will produce considerably great impacts to the growth path of Chinese economy; which we have demonstrated by the Dynamic With and Without Test based on the simulation results.
It follows that: in the earlier stage of planning period, the natural growth trajectory or other trajectory which are derived as the result that the avalable exogenous investment fund has been invested other objects such as ordinary roads, port facilities, etc. than an expressway network have generated the higher growth rate than that of the economy in which the exogenous investment found had been concentrated to the Expressway Network; however, in the latter period, the economic growth 'with' the expressway network has overwhelmingly dominated over that 'without' the expressway.
That is to say, it has been proved that the expressway network-oriented development program realizes the greatest 'takeoff-accelerating effects,' compared to the other alternative economic growth paths. Namely, the all-embracing cost of expressway service among various transport services as a derived demand is the cheapest; thata is, it is confirmed that the most efficient set of activities of the comprehensive opportunity cost (proxy index of social benefits) is chosen among many alternative sets. In this way, we have attained our predetermined targets.
