进口中间品质量与企业出口绩效

Quality of Imported Intermediate Products and Export Performance of Firms

本文构建了贸易自由化背景下进口中间品质量与企业出口绩效的理论模型,分析了进口中间品质量升级对企业出口绩效提升的影响机理,并利用2005-2008年海关贸易数据和中国工业企业数据进行实证检验。研究发现,整体上看,进口中间品质量升级显著地促进了企业出口绩效的提升。在进行异质性分析之后,结果显示,进口中间品质量的提高对加工贸易企业、处于中高技术行业和低融资约束企业的出口绩效的促进作用更大,过度依赖进口会减弱进口中间品质量升级对出口绩效的提升效应,并且进口来源地的不同也会对企业出口绩效产生差异性影响。进一步研究发现,进口中间品质量更多是通过广延边际来提高出口绩效。本文的研究为中国加快外贸结构调整提供了有益参考。

This paper constructs a theoretical model to analyze the quality of imported intermediates and export performance of firms under the background of trade liberalization,and uses customs trade data and Chinese industrial enterprise data from 2005 to 2008 to do Empirical test.The results show that the improvement of the quality of imported intermediate products is very important for export performance of firms which are in middle and high-tech industries and with low-margin financing Constraints,while over-reliance on imports will weaken the impact of quality of intermediate products on the export performance,and the different sources of imports makes it performance heterogeneity.Further study found that the quality of imported intermediate products is more through the extension of margin to improve export performance.The research provides a useful reference for China to speed up the structural adjustment of foreign trade.
