中文摘要：

随着技术进步和贸易自由化发展,在全球范围内组织生产的跨国公司所主导的全球生产网络迅速发展并不断深化。全球生产网络为发展中国家融入全球经济体系、实现技术进步和产业升级提供了契机。同时,中国经济发展进入＂新常态＂,出口贸易的发展方式亟待转变,对出口产品升级的研究显得尤为重要,而参与全球生产网络可能是中国出口产品升级的重要途径。本文利用2000-2011年中国海关贸易数据库对中国出口产品质量进行了测算,并以此为基础衡量出口产品升级。研究发现,中国出口产品质量有波动上升迹象,东中西区域产品质量基本呈现递减趋势。统计分析结果表明,参与全球生产网络直接促进了中国出口产品的升级,尤其是深入融合到价值链中对出口产品质量有明显的正向促进作用。东部地区的研发投入能够促进出口质量升级,但研发投入不能通过提高垂直专业化的程度来提升质量,印证了出口企业提升价值链地位能力的不足。地区财政自主权在中部地区和东北地区起到了至关重要的作用,并且地方政府倾向于支持技术密集型产品的升级。

英文摘要：

Organized globally and led by trans-national enterprises,global production networks（GPNs） develop rapidly along with the advancement of technology and deepening of trade liberalization.GPN provides great opportunities for developing countries to blend in global economy and realize their technological advance,as well as value chain upgrading.Facing the pressure of shifting model of economic development,China has urgent need of optimizing export trade though she has experienced marvelous success especially on export trade during the past few decades,so that the study on export product upgrading can be particularly important.Based on such consideration,this article focuses on how participating GPN influences China＇s export product upgrade.This article uses the conception of quality to quantitively describe product upgrade,and we calculate the product quality based on data of customs trade database from 2000 to 2011.The result shows that export product quality presents a declining trend from east to west of China,and the average quality of the whole country fluctuates a lot during 2000-2011 with a slight rising trend showing up recently.We then build several econometric models to examine whether participating in GPN matters,and how exactly this influence works.The results show that participating in GPN has remarkable influence on export product upgrading especially in eastern China,but market dispersion does not help in product upgrading.We also find that RD investment cannot promote regional position in global value chain in eastern China,forming a typical ＂Low-end lock-in＂.Capitaland technology-intensive products benefit a lot from participating in GPN while labourintensive exports may open markets with low-quality products.Fiscal decentralization is a key determinant in eastern and central provinces,and local governments tend to give more support to technology-intensive product upgrading.
