摘要
本文基于1998～2010年28个省市的面板数据,采用门槛效应模型,研究了我国人力资本在贸易开放对制造业高技能劳动力和低技能劳动力工资差距影响中的门槛效应。研究结果表明:以贸易开放和出口开放为依赖变量时,人力资本存在单一门槛效应,并且当人力资本小于门槛值时,贸易开放和出口开放会扩大劳动力工资差距,但是这种影响并不显著,当人力资本大于门槛值时,则会显著地缩小劳动力工资差距;以进口开放为依赖变量时存在双重门槛效应,当人力资本小于前两个门槛值时,进口开放会显著地扩大劳动力工资差距,当人力资本大于第二个门槛值后,会扩大劳动力工资差距,但是这种扩大的趋势变得不再显著。同时,本文以贸易开放的人力资本门槛值为标准划分出到2010年17个省市处于低人力资本区,11个省市处于高人力资本区。
Based on the panel data of 28 provinces during 1998 -2010, the paper analyze the threshold effect of the human capital on the trade openness to high-skilled labor and low-skilled labor＇ s manufacture wage gap in China through the threshold effect model. The results of the study show that the human capital has a single threshold when trade openness and export openness are the dependant variables. As long as the human capital is higher than threshold value trade openness can broaden the wage gap. While the human capital is lower than threshold value, trade openness will narrow the wage gap significantly. As the same time, the human capital has double threshold effect to the dependents variables of import openness. As long as the human capital is higher than threshold value, import openness can broaden the wage gap significantly. But this expansion becomes no longer significant while the human capital is lower than threshold value. To threshold value of trade openness, there are 17 provinces belongings to the lower human capital area and 11 provinces belongings to the higher human capital area in 2010.
