中文摘要：

21世纪以来,中国制造业出口质量如何变化？回答这一问题要求我们准确测算出口质量。目前广泛使用的出口质量测算方法在理论上仅考虑需求面而忽略供给面,其实证的关键价格变量存在测量误差,且得到的测算值跨时跨国不可比。为了解决这些问题,我们系统地考虑了供给面和需求面因素,提出基于微观数据的新的出口质量测算办法。测算结果表明,2000—2006年中国制造业出口质量水平总体上升15%。我们从不同角度全面刻画了出口质量的变化情况。

英文摘要：

How does China＇s manufacturers＇ export quality evolve since 2000？ One can- not answer this question without reliable export quality measures. We argue that existing ap- proaches to estimate export quality suffer from pitfalls that 1） they only consider demand-side while ignoring supply-side in theoretical framework and 2） they use prices with measurement errors and generate estimates not comparable across years/destinations. To avoid these pitfalls, we propose a new approach applicable to micro-level data by jointly considering supplyside and demand-side information. Our results show that from 2000-2006, Chinese export quality has increased by 15 %. We then characterize export quality from various perspectives.
