本文在引入内生技术选择假设的新框架下考察了贸易开放如何影响贸易国内部和贸易国之间的工资不平等。这一假设意味着，以及作出劳动力选择，我们的模型中的企业同时选择采用不同的技术组合，而不是简单地利用标准的常数技术，在大多数以前的研究假设。理论上，我们发现内生技术选择部分地吸收了非熟练-熟练劳动力供给比例对一国内部相对工资的负面影响。此外，与标准不变技术模型相比，使用来自52个国家的数据校准的新框架产生定性和定量不同的结果，运输成本对两国之间的相对工资的影响。具体而言，在有些情况下，这种差异会对运输成本降低对工资不平等的影响产生相互矛盾的解释。在标准不变技术模型中，贸易开放程度越大，两国间的工资差距越明显;在内生技术选择模型中，贸易开放程度越大，两国间的差距越小。
This paper investigates how trade openness affects wage inequality within and between trading countries under a new framework that incorporates the endogenous technology choice assumption. This assumption implies that as well as making a labor choice, the firms in our model simultaneously choose to adopt different technology compositions, rather than simply utilizing the standard constant technology, as assumed in most previous researches. Theoretically, we find that the endogenous technology choice partially absorbs the negative effect of the unskilled-skilled labor supply ratio on the relative wage within a country. Furthermore, compared with the standard constant technology model, the calibration of the new framework using data from 52 countries yields qualitatively and quantitatively different results for the impacts of transport costs on the relative wage between the two countries. Specifically, there are cases in which this difference generates contradictory interpretations of the effect of a transport cost reduction on wage inequality. For several pairs of countries, the wage differential between two countries becomes more evident in response to trade openness in the standard constant technology model, whereas in the endogenous technology choice model, the gap becomes narrower.
