環(huán)比增長率=（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%。環(huán)比表示的是連續(xù)兩個(gè)統(tǒng)計(jì)周期（比如連續(xù)兩月）內(nèi)的量的變化比，即是按照兩期統(tǒng)計(jì)量進(jìn)行統(tǒng)計(jì)的。環(huán)比增長率=（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%。
