中文摘要：

利用1997年至2007年177个国家或地区分产品双边贸易流量数据,探讨不同国家或地区出口产品的技术水平以及影响因素。依据贝叶斯模型平均方法的实证分析中,研究发现除了传统的国家特征变量的积极作用以外,例如要素禀赋、研究与发展和贸易开放度等,体现金融发展水平的相关指标对一国出口产品技术水平具有重要的影响作用。综合上述研究和发现,中国出口产品技术水平与贸易发展不存在＂Rodrik之谜＂。

英文摘要：

This paper discusses the export sophistications across 177 countries or regions over the period 1997-2007 using bilateral trade flows dataset. Based on the sample data, we can not support the so called ＂Rodrik Paradox＂; and by using Bayesian Model Averaging （BMA） method, we explore the determinants of the export sophistication and find that some country character variables, such as the factor endowment, R＆D expenditure and trade openess, influence the level of export sophiscation. Besides, those financial development also play an important role. Finally, some policy implications will be given based on the empirical anylysis.
