工資性別歧視之分解：分量迴歸分析

本研究同時使用新近發展的分量迴歸 ( quantile regression ) 和傳統均數迴歸，分別估計男女工資函數，並透過不同工資差異分解的模型，探討臺灣地區男女性受雇人員在不同工資水準下邊際報酬的差異、歧視程度的變化和跨時趨勢。有別於大多數的既有文獻，只在傳統均數概念下探討相關議題。實證結果發現：男性工資普遍高於女性，兩者的差異絕大部分歸因於歧視部份。性別歧視程度大致隨著工資水準的提高而下降。近年來兩性工資的差距有縮小的趨勢，但是女性受到的歧視程度不降反升，反映女性員工在工作職場上仍受到相當不平等的待遇，值得勞工當局的關注。

This research simultaneously uses the quantile regression model which is recently developed and the traditional mean regression model to estimate the male and female wage function. And penetrating the different models of decomposition of gender difference, discusses the marginal return difference, the discrimination degree change and the cross time tendency of men and women employed under the different wage level in Taiwan. Aside from the well-developed ordinary least square analyze in the existing literature. Three conclusions are found in this paper. First, the male’s wage level generally is higher than the female’s and the wages difference discriminates occupies the majority. Second, the sex discrimination degree approximately drops along with the wage level enhancement. Third, the wage gap between male and female is reducing in recent years, but the female received the discrimination degree is actually rising. This phenomenon deserves further consideration for future policy suggestion.
