文章从外贸新形势视角,提出了全球价值链嵌入深化、环境规制加强及劳工成本攀升等新因素影响中国出口国内技术复杂度的理论假设。借鉴Hausmann et al.(2007)和姚洋、张晔(2008)的方法 ,文章测算了2002~2012年剔除了进口中间投入品技术含量后的中国工业行业出口国内技术复杂度,并采用系统GMM方法进行了实证检验。研究发现:实证结果支持全球价值链嵌入对中国出口国内技术复杂度的倒U型影响假说以及环境规制的促进作用,但劳工成本的提升作用并没有得到与理论假设相符的结论;此外,资本、外资及制度因素也均能显著提升出口技术复杂度,而研发却一定程度上阻碍出口技术复杂度的提高。
From the perspective of the new situation of foreign trade, the article puts forward the theoretical assumptions that new factors such as deepening global value chain embedding, environmental regulation and rising labor costs affect the technical complexity of China’s exports. Using the methods of Hausmann et al. (2007) and Yao Yang and Zhang Ye (2008), the paper estimates the technical complexity of China’s industrial exports after removing the technical content of imported intermediate inputs from 2002 to 2012 and adopts the system GMM Method was tested empirically. The results show that the empirical results support the inverted U-shaped influence hypothesis of global value chain embedding on the technical complexity of China’s exports and the promotion of environmental regulation. However, the role of labor costs in raising the costs has not been consistent with the theoretical assumptions. In addition, capital, Both foreign investment and institutional factors can also significantly increase the technical complexity of exports while R & D hinders the improvement of export technical complexity to a certain extent.
