Service producer prices

The service producer price index (SPPI) is defined as an output price index for the service production of resident producers. It has two main goals. The first is to be a short-term indicator of the business cycle. In this respect SPPI has to reflect changes in prices as fast as possible. The second is to be a suitable deflator for value developments. SPPI should thus represent all output as defined in National Accounts and follow, as closely as possible, the accrual principle in recording prices. Data are not seasonally adjusted.服务生产者价格指数（SPPI）被定义为常住生产者服务生产活动的产出价格指数。其主要目标有两项：其一，作为经济周期的短期观测指标，为此SPPI需尽可能快速地反映价格变动情况；其二，作为适配价值变动核算的平减指数。因此，SPPI应覆盖国民经济核算中定义的全部产出，并在价格记录环节尽可能严格遵循权责发生制原则。本次公布的数据未进行季节性调整。
