加工贸易升级机制实证分析

An Empirical Analysis of Upgrading Mechanisms of Processing Trade

文章从全球生产网络视角出发,基于广州242家企业样本数据,重点考察加工贸易的升级机制。实证研究发现：企业技术创新能力、管理能力和国内产业配套能力是影响加工贸易升级的主要因素。技术创新能力和管理能力的作用是直接的,而产业配套能力的作用是通过前两个因素而间接实现的,这表明企业能力是加工贸易升级的核心因素和内在源泉。出口退税政策的影响不显著,说明实施出口退税率差别待遇不再是推动加工贸易升级的有效工具。

This paper investigates the upgrading mechanisms of processing trade by using the data of 242 sample firms in Guangzhou from the perspective of global production networks.The empirical results suggest that： （1）both technological capabilities and management capabilities of firms and domestic industrial supporting capabilities have positive effects on the upgrading of processing trade,（2）the effects of both technological capabilities and management capabilities are immediate while the effects of domestic industrial supporting capabilities are achieved via the former two factors,which shows that the capabilities of firms are the ingenerate sources of the upgrading,and（3）the policy of tax refund has no significant effects on the upgrading,which shows that the treatment of differentiated tax refund rates is not an effective tool.
