简介

交易成本是指买卖双方在交易过程中所产生的成本。数据来源于对70家汽车公司供应商（30个美国，20个日本，20个韩国人）的面对面访谈，为最大限度地减少关键线索者的偏见， Dyer, J. H., & Chu, W.(2003)询问了最相关的知情者——每家汽车制造商的采购经理与工作负责的供应商主管。

计分方法

交易成本量表共2道题，计分方法如下：
Exante transaction costs (ExanteTC)=(total annual “person-days” of face-to-face time spent) × (percent of time spent on price negotiation/contracting) ÷ (supplier sales to the buyer).
Expost transaction costs (ExpostTC)=(total annual “person-days” of face-to-face time spent) × (percent of time spent haggling and assigning blame for problems) ÷ (supplier sales to the buyer).
