事故の社会的損失最小化に関する理論的・実証的研究

(1998)首先给出了将事故和灾害造成的社会损失降到最低的理论框架。(参考文献1)其次，阐明了道路交通事故的主要原因，比较了日本和国外的案例。(参考文献2)本理论研究的目的是寻求最优预防投资的解决方案。(参考文献3)(1999)(1999)(1999)关于自然灾害，我发现灾害死亡人数一方面呈下降趋势，但其造成的经济损失呈上升趋势。(参考文献4)试图形成最优预防投资理论。在这种情况下，关键的概念是安全和降低成本之间的权衡关系。指出了权衡关系分析中的一些问题，并以日本防洪措施为例进行了分析。

(1998)At first, I showed the theoretical frame to minimize the social loss by the accidents and disaster.(reference 1)Secondly, I clarified the main causes of road accident, comparing Japanese case to the foreign countries case.(reference 2)The purpose of this theoretical study is to get solution of optimum preventive investment. I developed the model of net benefit maximization by the use of the car, and succeeded to get solution.(reference 3) (1999)(1999)Concerning natural hazard, I found some important facts that the number of deaths by the disaster showed a declining tendency on the one hand but the monetary loss of damage by it showed increasing tendency.(reference 4)I tried to form the theory of the optimum preventing investment. In this case, the key concept is the trade-off relationship between the safety and the cost reduction. I pointed out some issues on the analysis by the trade-off relationship and analyzed the case of the measure against flood in Japan.(reference 5)
