（注）国内企業物価指数では、便宜上、国内品（813.03）＋輸入品（186.97）＝1000.00とするウエイトを用いて、実際の指数計算を行っている。このため、連鎖方式による国内企業物価指数においても、総平均を813.03とするウエイトを使用している。
Note: The weight of domestic goods (813.03) is used for calculating the indexes of the DCGPI.  The same weight is also adopted for calculating the DCGPI using the Chain-weighted Index Formula.
