政府补贴提高了中国制造业企业出口产品质量吗

Does Government Subsidy Improve Chinese Manufacturing Firms' Export Quality

本文利用2000-2006年中国工业企业数据与海关贸易数据,采用基于倾向得分匹配的倍差法(PSM-DID)进行实证研究,发现政府补贴显著提升了企业出口产品质量;本文还检验了政府补贴对不同类型企业出口产品质量的异质性影响,结果表明,政府补贴对民营企业、一般贸易企业以及融资约束程度高的企业出口产品质量的提升作用尤为明显;本文还进一步考察了政府补贴影响企业出口产品质量的作用机制,发现政府补贴主要通过增加研发创新和提升进口中间品质量的渠道促进企业出口产品质量升级。本文研究对于全面评估中国政府补贴的经济效果和提升中国企业出口竞争力具有重要的政策启示意义。

How does government subsidy affect Chinese manufacturing finns export quality？ Based on the firm-level data of China over the period 2000- 2006, this paper combines propensity score matching with difference-in-difference （PSM-DID） to empirically study the impact of government subsidy on firms＇ ex- port quality, and find that government subsidy significantly improves finns＇ ex- port quality. In addition, we test the heterogeneous impact of government subsidy on export quality of different types firms, and the results show that the positive impact is more pronounced for private finns, general trade finns, and finns with higher financial constraint. Furthermore, we investigate the potential mechanisms through which government subsidy influences firms＇ export quality, and find that government subsidy increases firms＇ export quality via innovation and intermedi- ate input quality upgrading. This paper provides some important implications for evaluating the effect of Chinese government subsidy as well as raising finns＇ ex- port competitiveness.
