随着技术进步所导致的产品科技含量的增加以及贸易自由化导致的传统贸易政策工具作用的减弱,标准化正逐渐成为继配额、关税之后的新贸易保护政策工具,对国际贸易的发展形成阻碍作用。文章首先通过建立一个不对称寡头模型分析了标准化的贸易保护效应,从而明确了为什么发达国家可以把非歧视性的技术标准作为新的贸易保护政策工具。然后从实证角度验证了日本标准化水平的提高对中国农产品出口具有较强的贸易保护效应,为理论模型提供了实证支持。
With the increase of technological content resulting from technological progress and the weakening of traditional trade policy instruments resulting from trade liberalization, standardization is gradually becoming a new trade protection policy instrument after quotas and tariffs, which hinders the development of international trade . First, the article analyzes the standardized trade protection effect through the establishment of an asymmetric oligopoly model, thus making it clear why developed countries can adopt non-discriminatory technology standards as a new trade protection policy tool. Then it proves that the improvement of the standardization of Japan has a strong trade protection effect on the export of agricultural products in China from empirical perspectives and provides empirical support for the theoretical model.
