| 摘要: |
| 运用2005—2008年中国14个制造业企业面板数据，分析企业出口的自我选择效应和出口中学效应，结果表明：中国制造业企业出口与生产率的关系违背异质性企业贸易模型，自我选择效应不显著，并且存在“生产率悖论”；出口中学效应也不显著。虽然出口企业的生产率与出口规模正相关，但在控制其他影响出口规模的变量后，生产率与出口规模则呈现负相关；在控制其他影响生产率的变量后，出口规模与生产率同样也会呈现负相关。中国企业出口的自我选择效应不显著的原因在于其加工贸易等现实条件与经典理论假设的背离；而中国企业出口中学效应不明显的重要原因则在于其自我选择效应的不显著和规模报酬递减。 |

| Abstract: |
| Based on panel data of 14 manufacturing enterprises during 2005—2008, after analysis of self-selection effect and learning by export effect from manufacturing enterprises export, the results show that the relationship between Chinese manufacturing enterprises export and productivity violates heterogeneous enterprise trade model, that self-selection effect is not obvious, that there is "productivity paradox", and that learning by export effect is not significant. Although there is positive correlation between productivity and export scale of export enterprises, there is negative correlation between productivity and export scale after other variables influencing export scale are controlled, meanwhile, when other variables influencing productivity are controlled, export scale is also negatively related to productivity. The cause of insignificant self-selection effect of China’s enterprise export lies in the inconsistence of processing trade and realizing condition with classic theories, while the main reason for unobvious effect of learning by export results from unclear self-selection effect and scale profit degression of export enterprises. |
