净出口指数（TB）
净出口指数指（TB）（又称为：贸易收支顺差，Trade Balance）指的是一国某产品的出口总额和进口总额之差，其公式表示为
TBij = Xij - Mij
公式之中，TBij 代表i国j产品的净出口指数；Xij 代表i国j产品的出口额；Mij 代表i国j产品的总进口额。TB指数能够反映一国某产品从国际贸易中收取的净收入，如果TB数值为证表明该产品属于出口创汇类型，TB数值为负则表示该产品属于进口代替型。但是，使用TB指数对某国某产品的出口竞争力进行评价也要注意，本国该产品的TB指数为负不一定表明该国该类产品的竞争力下降而可能是因为国内对于该产品的消费需求大于国内生产能力。
