This paper is based on the multinational panel data of 226 countries and regions from 1985 to 2016,using the ratio of industrial female employees to industrial male employees to measure gender discrimination in industrial employment,measuring the degree of trade freedom forwardly and reversely by foreign trade dependence and MFN weighted average tariff rate respectively,analyzing the impact of trade freedom on the ratio of industrial employment of women to men by empirical test.The lag phase of foreign trade dependence and weighted MFN weighted average tari ff rate are used as the instrumental variables of the two models to deal with the endogeneity problem.The empirical result shows that increasing the degree of trade freedom will reduce the ratio of industrial female employees to industrial male employees,so trade freedom aggravates the gender discrimination in industrial employment.
