进口产品种类、质量与企业出口产品价格

Imported Inputs,Quality and Export Prices

本文在异质性企业贸易模型基础上,引入内生产品质量和内生进口产品种类集构建理论模型,并基于2000-2006年中国海关和工业企业生产数据验证了模型的预测和运行机制。研究表明,当产品质量差异幅度较大时,进口中间产品种类越多的企业,最终产品质量和定价也越高;企业为提高最终产品质量会使用更高质量的中间产品,并向生产最终产品的劳动者支付更多工资,以激励员工在生产中付出更多努力。本研究有助于理解企业进口决策对出口价格的作用及其影响机制,并为中国外贸发展从规模扩张向质量效益提高转变提供了新的研究视角。

This paper analyses the relationship between firms input varieties and export prices,incorporating both endogenous product quality and endogenous import varieties into a heterogeneous firm trade model.Using the combined dataset formed from Chinese customs data and Chinese firm-level data from the National Bureau of Statistics of China(NBSC),it is found that when differentiation in terms of product quality is greater,firms import more input varieties,and the quality and prices they set for the final goods are higher.In order to promote improved product quality and thus increase export prices,firms should use higher quality imported inputs and pay better wages to the employees responsible for the final product manufacturing process,so as to encourage them to put more effort into their production.This paper helps to better understand the role and impact mechanism of firms import decisions on export prices,and it provides a new perspective to boost Chinese globalization by transitioning from large-scale expansion to high-quality promotion.
