| Research Abstract |
The study is aimed at developing the tool to evaluate the impacts of largescale transport improvements on regional economies. We have been working on the model which primarily intended to describe the Chinese economy.
(1)The initial model involves very complicated iterative procedures. We revised the computational procedure of the model to simplify its coding, and calculate the benchmark equilibrium for the new base year of 1987. The comparisons of our results with the Peking table and the interim interregional table available for that year are reported in Chapter 4.
(2)The initial model is intended to calculate prices and quantities that attain the network equilibrium. In this regard, the model shares the similar goal as the CGE model though it considers only a part of equilibrium conditions. Thus we rebuilt the model as a multi-regional CGE model.
(3)To help understanding the basic framework of the model, the simplified model for a closed economy consisting from firms, transport firms and households is presented in Chapter 2. It is shown that the equilibrium conditions for the problem are fully consistent with the interregional input-output system.
(4)The full model that incorporates the public sector, foreign countries, and savings-investment behavior is presented in Chapter 3 with consideration of the availability of Chinese statistics. The possible modifications to the model that correspond to the alternative sets of endogenous variables are also discussed.
(5)The model framework is applied to the assessment of economic losses caused by the Hanshin-Awaji earthquake. This version of the model, presented in Chapter 5, considers the equilibrium only in the quantity sphere as the price changes due to the transport interruption were minimal. In return, three transport modes are introduced to closely examine the effects of the damages in transport facilities.
