Outline of Final Research Achievements

This research project has focused its analysis on the impact of lower transport costs on the sustainability of trade agreements. In particular, it has provided a framework that enables the analysis of situations where governments implement multiple policies, not only trade policies but also environmental policies and international infrastructure investment, and has identified how these policies are affected through international trade. Basic analysis has shown that lower transport costs encourage more stable trade agreements between two asymmetric countries. The removal of transport costs between countries caused by factors other than tariffs (e.g. barriers due to cultural and language differences, cumbersome customs procedures, etc.) can make trade agreements between the countries concerned stronger.

Academic Significance and Societal Importance of the Research Achievements

貿易協定に関する理論分析を行う研究において、国家間の輸送費用を取り入れた点に意義があった。国際経済学の実証研究によれば国家間の輸送費用は無視できない水準であることが明らかにされてきた。そのため、これを受け現代の国際貿易体制を説明する上で必要不可欠な貿易協定に関連する諸帰結が国家間の輸送費用にどのように左右されるのかを分析することで貿易協定に関する学問分野に新たな知見を加えることができた。
