PPI

PPI是Producer Price Index,中文含义是生产者价格指数,可以理解为社会企业生产商品的平均成本,包含原材料、半成品和最终生产品三个阶段的物价信息。PPI数据源自9大类商品,包括燃料、动力类;有色金属类;有色金属材料类;化工原料类;木材及纸浆类;建材类(钢材、木材、水泥);农副产品类;纺织原料类;工控产品类。PPI是生产,CPI是消费,显然是先有生产,再有消费,所以PPI是CPI的前兆。一般价格波动会首先影响到生产端PPI的数据,再由产业链向下游扩散,最后反映到消费者的衣食住行上。

CPI

CPI是居民消费价格指数(consumer price index)的简称。居民消费价格指数,是一个反映居民家庭一般所购买的消费商品和服务价格水平变动情况的宏观经济指标。它是度量一组代表性消费商品及服务项目的价格水平随时间而变动的相对数,是用来反映居民家庭购买消费商品及服务的价格水平的变动情况。

其变动率在一定程度上反映了通货膨胀或紧缩的程度。
