摘　　要：本文利用宁波市2007-2011年出口企业的面板数据,对新-新贸易理论进行了实证分析。实证结果表明,生产效率对出口的影响与Melitz(2003)和大部分先前的研究结果及其他国家和地区的经验结果基本相同,生产效率越高的企业出口越多,这表明宁波市出口企业中的"生产率悖论"并不存在。但在对外投资的企业中,生产效率越高的企业,对外投资数额越少,这与之前的研究和预期结果并不一致,出现了"生产率悖论"。针对这一结果,本文从宁波市的地区特点和企业性质方面进行了解释。This paper presents an empirical analysis on the New-New Trade Theory based on panel data of export enterprises in Ningbo city from 2008 to 2010. As the result shows, the influence of production efficiency on exports basi-cally converges with results of Melitz （2003） and most of other previous studies conducted in the setting of other countries and regions, that is, the enterprise pro-duction efficiency is in positive relation with the export volume, suggesting that there is no so-called ＂efficiency paradox＂ among export enterprises in Ningbo city. Among outside investing enterprises, however, the higher the productivity is, the less the investment amount, an inconsistency with expected results or results from previous studies, giving rise to the so-called ＂efficiency paradox＂ . This pa-per also seeks explanation for these findings from both regional characteristics and entergrise attributes of Ningbo citv.
