社会信任与出口比较优势——基于IVTSLS和PSM方法的实证研究

Social Trust and Export Comparative Advantage:an Empirical Investigation Based on IVTSLS and PSM Method

基于63个国家222个行业的出口贸易数据,采用工具变量两阶段最小二乘法(IVTSLS)和倾向得分匹配方法(PSM)考察了社会信任对出口比较优势的影响。实证结果显示,社会信任度高的国家在契约密集度高的产品上拥有比较优势,并且在控制了要素禀赋、人均收入水平和金融发展指数等变量后,上述结论依然成立。该结论对于我国加强社会信任建设、改善出口商品结构和加快产业结构升级具有重要的政策含义。

By using a dataset of international trade across 63 countries and 222 industries, and employing instrumental two-stage least square method and propensity score matching method, this paper investigates the effects of social trust on export comparative advantage. The results show that, countries with high trust index will have a comparative advantage in contract intensive industries, even after controlling factors such as factor endowment, per capita income and financial development, the above results still hold. Therefore, it has strong policy implications for the government to improve export structure and industrial structure by strengthening social trust.
