摘要
本文采用产品层面的关税数据和贸易数据,将产品归类到行业,在测度贸易自由化程度和出口产品质量的基础上,利用2000-2011年中国27个制造行业的面板数据,实证分析贸易自由化对出口产品质量的影响及其在不同行业间的差异性体现。实证结果表明:以最终产品关税率和中间投入品关税率为表征的贸易自由化有利于出口产品质量的提升,且中间投入品关税率的作用更为明显;在不同特征的行业中,贸易自由化对出口产品质量的影响是不同的,其对研发强度低、行业质量阶梯短、人均工资低及劳动资本密集度小的行业的出口产品质量提升作用更为显著。
This paper uses the product-level tariffs and trade data to classify the products into industries. Then on the basis of the measure of the extent of trade liberalization and the quality of expert products, this paper empirically analyzes the effect of trade liberalization on the export product quality and the different effects among different industries by using panel data of China＇s 27 manufacturing between 2000 and 2011. The results show that trade liberalization which is char- acterized by output tariff and intermediate inputs tariff has a significant positive impact on the quality upgrading of expert product, and intermediate inputs tariff is more effective. In different industries, the effect of trade liberalization on export product quality is different. The effect is more significant in those industries with low R＆D intensity, short quality lad- ders, low per capita wage or low per capita volume of capital.
