从交易特征的三个维度(资产专用性、交易频率、交易的不确定性)出发，结合市场交易地位和家庭个性特征，根据258户农户的入户调查结果，采用 logistic回归模型，对交易成本与农户贫困发生的概率之间的关系进行回归，回归结果显示高交易成本与高贫困发生率显著相关，降低农户参与市场竞争的交易成本，将有助于精准识别贫困农户并有针对性地开展精准帮扶工作。%Starting from the three dimension of transaction characteristics (capital specificity,transaction frequency,transac-tion uncertainty ), combining the market transaction status and personal characteristics of household, based on the investigation of 258 peasant households,using the logistic regression model,this article regresses the relationship between the transaction cost and probability on farmer poverty.The article draws a conclusion that high transaction cost is remarkably rele-vant to the occurrence rate of peasant households.So,if the transaction cost can be effectively reduced when peasant house-holds participate in market competition,it would help to discriminate poor peasant households more accurately and carry out work to help them more contrapuntally.
