摘　　要：研究在拥有先验信息的情况下是否进行抽样调查这一决策问题。首先分析期望信息收益（ＥＶＳＩ）和净期望信息收益（ＥＮＧＳＩ）对抽样调查决策的不完全性，然后提出一种用传递熵进行事前决策的方法，并对抽样调查的意义进行了简要讨论。The paper discuses how to make an ex-ante decision of sampling information when decision-maker has prior sampling information. We first analyze the shortcomings of Expected Value of Sampling Information(EVSI) and Expected Net Gain from Sampling Information(ENGSI) in evaluating sample investigating, then develope an ex-ante decision method using transference entropy to decide if more sampling investigating is profitable. The meaning the sampling investigating is discussed in brief.
