摘　　要：我国学者运用帕氏公式测算我国价格贸易条件指数时经常得到大相径庭的结果,笔者认为这是由我国海关统计资料的数据缺陷造成的。文章提出采用"环比-定基"两步法测算价格贸易条件指数:第一步,采用环比的方法用帕氏公式测算每年与上年相比的进出口价格指数;第二步,用定基的方法以某一年为基期进行转换计算,测算出各年度与基期相比的进出口价格指数,然后用相同基期的出口价格指数除以进口价格指数测算价格贸易条件指数。通过"环比-定基"两步法可有效解决测算我国价格贸易条件指数的困境。In China, scholars generally obtain widely divergent results when they calculate the price index of China＇s terms of trade based on Paasche aggregative formula. This problem was attributed to the data imperfection of customs＇ statistical information. Therefore, in this paper, a ＂chain-based and constant-based＂ two-step method is introduced to calculate the price index of terms of trade. Firstly, based on Paasche aggregative formula, every period＇s price index of import and export is calculated with the ＂chain-based＂ method compared with its last period＇s. Secondly, the price index of import and export is calculated with the ＂constant-based＂ method compared with the benchmark period. Then, with the benchmark period＇s export price index divided by the import price index, the price index of terms of trade is obtained, which could be a practicable solution to the problem.
