For verification of such argument, the labordemandfunction categorized by business sector was estimated and the significance of the import price index was examined, based on which the statistical significance of correlation between the decline in prices of import products and the decrease in the number of workers was confirmed in the general machinery, transportation equipment and chemicals sectors (Table 2-1-3-13). この点を確認するために、業種別の労働需要関数を推計し、輸入価格指数の有意性を検定したところ、一般機械、輸送機械、化学については輸入品価格の下落と従業員の減少との相関関係が統計上有意であることが確認された(第2-1-3-13表)。 - 経済産業省
