Outline of Final Research Achievements

This study aims to develop a method for create true trade volume from trade statistics based on data fusion approach. As the results, the study built an identification system of factors affecting the discrepancies with trade statistics. In addition, Non-negative Matrix Factorization method was applied into the discrepancies with trade statistics as a newly data fusion approach. Finally, the effectiveness of trade regulation to mercury and mercury added products in the Minamata Convention was evaluated from the perspective of the trade discrepancy.

Academic Significance and Societal Importance of the Research Achievements

本研究成果の学術的意義は,貿易統計の不整合問題を「修正すべく統計的問題」から「活用すべき統計的性質」と再解釈することで,貿易統計の新しい用途とそのための新しい方法論を提示した点である.貿易統計の新しい用途である国際条約の実効性評価と,貿易統計の新しい方法論である不整合要因診断システムや非負値行列因子分解法はビックデータサイエンスに貢献するため,社会的意義の高い研究成果といえる.
