改革开放以来,我国轴承产品出口贸易快速增长.本文运用恒定市场份额模型(CMS),对我国轴承产品出口增长效应进行分析,以寻找出口增长的主要原因.分析结果表明,进口国的需求扩大是我国轴承产品出口持续增长的主要因素;商品结构效应和竞争力效应对出口的阻碍作用逐渐减小,且对2006~2008年期间的出口增长具有重要作用.对竞争力效应的近一步分解发现,体现我国劳动力资源禀赋特征的劳动密集型传统优势轴承产品竞争力效应不足,而技术密集型产品竞争力效应增长.并对提高我国轴承产品国际竞争力,实现可持续增长提出粗浅见解.“,”Since the implementation of reform and openness policy,China's exportation trade of bearing products develop quickly.This article uses constant market share model(CMS) to carry on the stage analysis on the exportation trade change of China's bearing products,and seek the primary causes for which the bearing exportation grow.The result discovers that the import countries' demand expansion is the major effect factor of the continual growth of Chinese bearing exportation;the exportation hindrance function of commodity structure change and competitive power change reduces gradually,and are a vital role for the bearing exportation growth during 2006-2008.With the detailed analysis of competitive power effect,it finds that competitive power effects of traditional superiority product incarnating China's labor force resources and comparative advantage feature,such as labour-intensive bearing products,are short,but technology-intensive bearing products increasing.According to the analysis,it finally puts forward some pointed proposals improving the exportation competitive power of Chinese bearing products.
