企业异质性与出口:来自浙江省的经验证据

Firm Heterogeneity and Export:Empirical Evidence from Enterprises in Zhejiang

文章运用2005～2007年418家浙江省企业面板数据，分析浙江省企业出口与生产率的内在关系。比较分析FE方法、RE方法和L-P方法在估计全要素生产率的不同结果，然后分别运用Lo酣模型和Probit模型比较分析出口与生产率的关系。结果表明：浙江省企业生产率与出口之间的关系支持“自选择”效应和“出口学习”效应。

This paper analyzes the intrinsic relationship between exports and productivity of enterprises with panel data of 418 enterprises in Zhejiang province from the years 2005 to 2007. Different methods are attempted to estimate the total factor productivity, including fixed-effects, random-effects and Levinsohn-Petrin productivity estimation. Then the logit model and probit model are applied to test the relationship between export and productivity. The empirical results show that the relationship between export and productivity in Zhejiang supports the self-selection effect and learning-by-exporting effect.
