本文通过对1992~2007年的机械行业中9个种类的面板数据进行实证检验,建立协整方程并对其进行误差修正,分析了我围机械行业中的标准存量与产业内贸易之间的关系。实证结果表明两者有着长期的均衡关系,机械行业中标准的使用会对该行业的产业内贸易水平产牛正的促进作用。标准的进入将在长期内改善我围的产业结构,促进产业内贸易发展。
The paper applies the panel unit root, panel cointegration and panel-based error correction models to investigate the causal relationship between standardization and intra-industry trade of the machinery industry in China based on the data from 1992 to 2007. The results show that there is an equilibrium relation- ship in the long-term between standard and the intra-industry trade.The growth of standard stock will significantly improve intra-industry trade.
