The estimation of the economic benefits of a public investment project should include not only the direct effects but also the indirect ones. The problem is seen even more clearly when considering projects involve investments for increasing assets in social overhead capital, such as roads, railways, ports, etc. These projects often show a direct benefits only, which may be less than unity if the services produced are not sold, but consideration of the benefits deriving from the execution of such projects often shows that they are of top priority. In these cases the most important benefits are indirect, since they make production possible in other sectors of the economy.In this drafting, we deal with an estimation of direct and indirect economic benefits to a region which derived from the public investment for port facilities, by preparing a simplified system as shown in Fig. 1.Thereupon, such economic benefits are defined as an increment of the net regional products. Then the econometric model and interregional input-output model are introduced to analyze each process of this system mentioned above.

Professor Fujioka analyzed the optimization behavior of consumers in a Deposit-Refund System in his paper which he published in <i>Studies in Regional Science</i>, vol. 29 No.3, 1998. Professor Oishi criticized Professor Fujioka's two stage maximization analysis as the strange case of Dr. Jekyll and Mr. Hyde in his paper which he published in <i>Studies in Regional Science</i>, vol. 32 No.1, 2002. Alternatively, he proposed a well-refined model of a unified Deposit-Refund Theory.<br>In this paper, first we provide a new model for the Deposit-Refund System Analysis. Second we conclude the new model is a specified one of the Oishi model because the two stage maximization of a representative consumer in the new one is consistent with the one stage maximization of the Oishi model <i>with strict assumptions</i>. Thirdly we conclude the Fujioka's is also a specified kind of the Oishi model because the Fujioka model should be identified as the new one from my point of view. Finally, we note that the two stage maximization <i>without strict assumptions</i> in the new model may be closely related to <i>the half-rationality</i>, a new concept which Professor Sakai, the President of the Japan Section of Regional Science Association International, introduces into regional scientists.
