Economic growth rate

Japanese: 経済成長率 - けいざいせいちょうりつ（英語表記）economic growth rate

The rate at which the size of a national economy expands over a certain period of time. It is usually expressed as the annual (or fiscal year) growth rate of gross national product (GNP) or national income (→ national disposable income). Economic growth rates can be expressed in two ways: nominal (expressed at current prices) and real (expressed at constant prices at a certain point in time), but it is common to use real growth rates that eliminate price fluctuations. For example, when asking about Japan's economic growth rate, it is expressed as the growth rate of real gross national expenditure (gross national product) compared to the previous year. In addition, the economic growth rate used in economic plans over a relatively long period of time (5 to 10 years) is calculated by compounding the above growth rate over the same period.

Japanese:

一定期間における国民経済の規模が拡大する速度。通常は国民総生産 GNPまたは国民所得 (→国民可処分所得 ) の年間 (ないしは年度間) の増加率で表わす。経済成長率は名目 (時価表示) と実質 (一定時点の不変価格表示) の2通りの表示法があるが，物価変動を除去した実質成長率を採用するのが普通。たとえば日本の経済成長率何%という場合，実質国民総支出 (国民総生産) の対前年度増加率をもって表わす。また比較的長期間 (5～10年) にわたる経済計画などで用いられる経済成長率は，同期間内の上記伸び率を複利で計算する。
