中文摘要：

基于我国1999～2006年的省际面板数据，研究了国际贸易、FDI等经济开放现象对熟练劳动供给比例的影响。与Avflos（2006）、Katz和Murphy（1992）的研究结果不同，对总体的实证研究表明，贸易依存度、FDI等经济开放因素通过教育投入而非熟练劳动相对工资对熟练劳动供给产生显著的正向影响，熟练劳动相对工资及工资与贸易依存度和FDI变量的交叉项对熟练劳动供给没有显著的作用，而教育投入变量与贸易依存度和FDI变量的交叉项对熟练劳动供给具有显著的正向作用，贸易依存度和投资份额变量对熟练劳动供给也有显著的正向作用。分类研究表明，地区的受教育程度、教育投入、熟练与非熟练劳动工资差距等特征差异是影响熟练劳动供给的重要因素。

英文摘要：

Based on China＇s 1999-2006 30 provincial panel data, this paper studies the impact of international trade, FDI and other economic opening up phenomena on the proportion of skilled labor supply. Different from Avalos＇s （2006）, Katz and Murphy＇s （1992） research results, the overall study finds that： trade dependence, FDI and other economic openness factors through education in- vestment rather than relative wages have significantly positive effect on skilled labor supply; relative skilled wages and cross-terms of wage and trade dependence, FDI do not significantly affect skilled labor supply; while education investment and cross-terms of educa- tion investment and trade dependence, FDI have significantly positive effect on skilled labor supply, trade dependency and investment share variables have significantly positive effect on skilled labor supply. Meanwhile, further research shows that areas classified by ed- ucation level, education investment, the wage gap between skilled and unskilled labor and other characteristics are the important fac- tors affect skilled labor supply.
