中间品贸易自由化对劳动资源配置效率的影响——基于中国工业企业数据的分析

On the Impact of Trade Liberalization of Intermediate Inputs on Allocative Efficiency of Labor:An Analysis of Chinese Industrial Enterprise Data

基于1998—2007年中国工业企业数据,实证研究了中间品贸易自由化对企业劳动资源配置效率的影响。结果发现,中间品贸易自由化显著提高了企业的劳动资源配置效率,这一影响在外资企业、低技术水平企业以及东部地区企业中尤为明显。借助工具变量解决估计中潜在的内生性问题后,主要结论依然稳健。进一步研究发现,由于调整成本的存在,中间品贸易自由化对国有企业的影响存在时间滞后效应,并且可能是通过降低企业中间品的单位投入成本促进了企业劳动资源的再配置。

On the basis of the data of industrial enterprises in China from 1998 to 2007,this paper studies the impact of trade liberalization of intermediate inputs on the allocative efficiency of labor.The results show that trade liberalization of intermediate inputs significantly enhances the allocative efficiency of labor resources in the enterprises,which is particularly prominent in the fully foreign invested enterprises,the low-productivity ones,and those located in East China.As the instrumental variable is employed to resolve the potentially endogenous issues in the estimation,the main conclusion still remains robust.Furthermore,the impact of trade liberalization of intermediate inputs on the state-owned enterprises exhibits lag effect due to the presence of adjustment costs.By lowering the costs of intermediate inputs can the re-allocation of labor resources in the enterprises probably be boosted.
