Outline of Research at the Start

本研究では、日本の各種経済指標と国内総生産(GDP)との動的関係を解析し、経済指標とGDPとのフィードバックループを解明するために、景気変動メカニズムに関する実証分析の統計モデルを構築する。また、構築した景気変動メカニズムの統計モデルに日銀短観、日経POS情報サービスや貿易・金融などのビッグデータを利用する方法を提案し、精確性と迅速性の両面から実用性の高い景気変動予測分析のツールを開発する。

Outline of Final Research Achievements

With the rapid development of ICT, the utilization of big data has become possible, and methods of data analysis are continually evolving. In this context, effectively utilizing big data to accurately and quickly grasp economic trends is an important issue not only for policymakers but also for economic entities such as entrepreneurs. This study aimed to achieve the following three points with a focus on the analysis of Japan's business cycles. First, we established a new method for analyzing economic trends using big data. Second, to establish this method, we developed basic modeling techniques and fundamental tools for statistical analysis. Third, we analyzed the dynamics in the relationship between economic fluctuations and related indicators, thereby broadly elucidating the mechanisms of business cycles.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、ビッグデータを活用した新たな景気動向分析法の確立や景気循環メカニズムの解明に貢献した。これにより、経済主体はより正確かつ迅速に景気の動向を把握し、政策当局は効果的な政策立案を支援できる。具体的には、本研究では新規の景気循環指標を構築する哲学と統計的手法の確立とともに、そのための時系列の成分分解のモデリング手法も開発した。また、景気変動と経済指標の関係におけるダイナミクスを分析し、景気循環のメカニズムを解明する方法論は世界的にも先端的な成果となるため、本研究は学術的にも、経済学や統計学の発展に寄与し、社会的には、経済活動の安定化や企業の戦略立案に大きな役立ちをもたらすであろう。
