摘要
中国出口产品质量是否得到提升,已成为摆在中国学者及政策制定者面前迫切需要得到深入研究的命题。利用2000—2006年间2500多万条中国海关数据,采用需求结构模型(DSM)以及多重工具变量,本文的研究发现是:(1)中国出口产品质量总体上表现出轻微下降趋势,但呈U型变化态势;(2)私营性质样本的出口产品质量表现出显著的U型变化态势和轻微下降特征,而其它所有制性质样本的出口产品质量则表现出上升态势;(3)大量低产品质量私营性质样本的短暂进入和退出出口市场,是导致中国出口产品质量U型变化的核心因素;(4)私营和外资性质样本对中国出口产品质量增长产生重要正向贡献。其中,私营性质样本的正向贡献最高,而国有性质样本的贡献显著为负。以上这些发现不仅为全面理解中国出口产品质量的变化和动因提供了经验证据,也为中国对外贸易政策的调整提供了有现实意义的参考依据。
It has become an urgent proposition faced by China scholars and policymakers whether the quality of China's export products get promoted. Using China Customs Database with more than 25 million data in year 2000--2006, the major crucial findings of this paper lie below, based on Demand Structure Model(DSM) and multiple instrument variables. ( 1 ) In general, the quality of China's export products has a slight downward trend, but the curve appears U type change; (2) the quality of export products in private samples appears significant U type change and a slight downward trend, while the trend upward in all other samples; (3) a core factor leading to the U type curve can be explained by a large number of low quality private samples entering and exiting export markets in short times; (4) private and foreign samples have important positive contributions to the growth of China's export product quality. Among them, private samples contribute the highest, while the SOEs' contributions significantly negative. All the above findings provide not only empirical evidence understanding changes and motivations of China's export product quality, but also meaningful reference for China's foreign trade policy adjustment.
