摘要
本文利用中国企业层面的微观数据,通过构建一个同时包含企业异质性、进口中间投入和出口国内附加值率(DVAR)的理论模型,分析中间投入品贸易自由化影响企业出口国内附加值率的作用机理,通过测度企业层面的中间品投入关税和DVAR考察中间品贸易自由化对中国企业DVAR的影响。在考虑了相关的内生性问题后,实证结果表明中间投入品的贸易自由化有利于中国企业DVAR的提高,中间品贸易自由化对不同地区、不同所有制类型企业DVAR的影响并不一样。本文结论为从企业出口国内附加值角度重新认识中间品贸易自由化提供了新的视角。
Based on the micro-data of Chinese enterprises,this paper constructs a theoretical model including enterprise heterogeneity,import intermediate input and export domestic value-added rate(DVAR),analyses the mechanism of the effect of trade liberalization of intermediate inputs on enterprises′export domestic value-added rate,and examines the impact of intermediary trade liberalization on Chinese enterprises′DVAR by measuring the input tariffs and DVAR of intermediaries at enterprise level.After considering the related endogenous problems,the empirical results show that trade liberalization of intermediate inputs is beneficial to the improvement of DVAR of Chinese enterprises,and the impact of trade liberalization of intermediate products on DVAR of enterprises of different regions and ownership types is different.The conclusion of this paper provides a new perspective for re-understanding the liberalization of intermediate trade from the perspective of domestic added value of enterprises′exports.
