本文利用WIOD-SEA数据库公布的最新数据,基于价格传导机制的理论推演,采用“委托工资回归法”就贸易开放对中国不同技能工人的工资水平及技能溢价的影响进行了“两步法”实证检验。与国内已有研究相比较,本文有三点开创性的发现:第一,以关税减让为表征的贸易开放对中国国内产品价格具有显著的负向影响作用;第二,该作用传导至劳动力市场,导致中等技能工人工资水平的提高和低技能工人工资水平的下降,从而扩大了技能溢价;第三,上述实证结论在对标准误估计偏误进行修正后仍然显著成立。
Based on the latest data released by the WIOD-SEA database and based on the theoretical deduction of the price transmission mechanism, the paper uses the “entrusted wage regression method” to study the impact of the liberalization of trade on the wage levels and skill premiums of different skilled workers in China. Law "empirical test. Compared with the existing domestic research, this article has three seminal findings: First, the trade liberalization characterized by tariff concessions has a significant negative impact on the domestic product prices in China; second, the effect is transmitted to the labor market , Resulting in an increase in the wage level of mid-skilled workers and a drop in the wage of low-skilled workers, thereby expanding the skill premium. Third, the above empirical conclusion is still significant after correcting the standard error in the estimation of errors.
