进口中间产品质量与企业生产率——基于广义倾向得分匹配的经验分析

Quality of Imported Intermediate Products and Enterprise Productivity——An Empirical Study Based on GPSM Method

结合2000—2006年间合并的微观企业数据,采用国际前沿方法 ACF计算了企业生产率,并参考Gervais(2015)和施炳展等(2015)的方法计算出企业进口中间产品质量后,以广义倾向得分匹配方法考察了二者的关系。研究结果表明,进口中间产品质量与企业生产率存在U型关系。对用OP/LP方法计算的企业生产率进行稳健性检验,发现U型关系仍然成立。

Productivity is of vital importance to the sustainable development of an enterprise. Based on Chinese firm-level production data and transaction-level data from 2000 to 2006,we use the international forefront ACF approach to calculate the enterprises productivity. Referring to Gervais（ 2013） and Shi Bingzhan（ 2015）,we calculate total factor productivity,and employ GPSM method to study the impact of imported intermediate products on enterprises productivity. The results show that there is a ＂U-shaped＂relationship between the quality of imported intermediate products and the productivity of enterprises. The ＂U-shaped＂relationship was still established when the OP/LP method is used to test enterprise productivity.
