同比和環(huán)比的區(qū)別
同比指的是本期統(tǒng)計(jì)數(shù)據(jù)與去年同期統(tǒng)計(jì)數(shù)據(jù)相比較;環(huán)比指的是本期統(tǒng)計(jì)數(shù)據(jù)與上期統(tǒng)計(jì)數(shù)據(jù)相比較。計(jì)算公式為:同比增長=(本期統(tǒng)計(jì)周期數(shù)據(jù)-去年同期統(tǒng)計(jì)周期數(shù)據(jù))÷去年同期統(tǒng)計(jì)周期數(shù)據(jù)×100%;環(huán)比增長=(本期統(tǒng)計(jì)周期數(shù)據(jù)-上期統(tǒng)計(jì)周期數(shù)據(jù))÷上期統(tǒng)計(jì)周期數(shù)據(jù)×100%。
