健康人力资本与性别工资差异

现有对性别工资差异的研究大多是基于教育、经验等人力资本对工资的影响进行分析而忽视了健康人力资本的作用。本文运用中国健康与营养调查数据，将健康人力资本引入工资决定模型，对我国劳动力市场上健康人力资本对工资的影响以及性别工资差异进行了实证分析。研究发现：健康人力资本是影响我国居民工资收入的重要因素；我国劳动力市场上存在明显的性别工资差异，女性工资显著低于男性；利用Oaxaca—Cotton的分解方法发现性别工资差异中大约只有20％可以被个体特征合理解释，余下的部分被认为是对女性的歧视和没能观测到的因素所致。健康人力资本对工资的边际贡献在性别之间的差异是性别工资差异的重要来源。

Existed studies of gender wage gap are mostly based on education, experience, and other human capital, they always ignore the role of health human capital. In this paper, using the China Health and Nutrition Survey data and introducing the health human capital into the wage model, we analyze the gender wage gap in the Chinese labor market. The results indicate that health human capital is the most important factor of influencing the wage income of Chinese residents; There is a clear gender wage gap in our labor market, the wage of women is significantly less than men; Using Cotton`s decomposition method, we found the differences of health human capital between women and men are significant sources of gender wage gap.
