技术性贸易壁垒的保护效应研究——基于“南北贸易”的MQS分析

金融危机引发的全球经济萧条环境下,贸易保护主义通常会出现抬头的趋势,本文基于此种背景分析了开放经济条件下,一国实施技术性贸易壁垒对本国企业的保护作用。文章将各国企业生产成本的差异假设加入到质量竞争模型中,结果发现,发达国家设置技术贸易壁垒后,如果发展中国家的低技术企业可以通过研发和投资或是政府补贴达到质量标准而继续出口,则两国企业提供的产品质量都会提高,发达国家高技术企业的利润将会下降。两国生产成本的差异性会影响均衡时的质量选择和政府补贴的最低额。模型结论表明,中国企业面对技术性贸易壁垒可以通过增加研发或政府扶植而实现整体的产业及贸易结构升级。

The Protection Effect of Technical Barriers to Trade: MQS Analysis of "South-North" Trade Model

Trade protectionism tends to be rising under global economic recession triggered by financial crisis. This paper investigates the protection effect of technical barrier to trade in an open economy and incorporates costs differences of manufactures into the quality competition trade model. We find that if the developed country set a technical barrier to trade,qualities of products provided by two manufactures will increase and the profit of the high-tech manufacture will decrease,as long as the low-tech manufacture can reach the standards by R&D or government subsidy and export its products to the developed country. Products quality in equilibrium and minimum government subsidy by developing country are related to cost differences. In a conclusion Chinese enterprises can achieve an overall upgrading of industry and trade by R&D or government support.
