服务业发展促进了出口产品质量提升吗

Does the Development of Service Industry Improve the Product Quality

本文研究了城市服务业发展对企业出口产品质量的影响。在理论层面拓展了Kugler和Verhoogen(2012)的理论模型,提出服务业发展影响企业出口产品质量的两大微观机制,即"分工效应"和"工资溢价效应"。在实证层面利用城市统计年鉴与工业企业数据库和海关数据库匹配,在细化的城市-企业维度上进行了相应的实证研究。结果表明,城市服务业发展整体上促进了企业出口产品质量的提升。这一促进作用通过"分工效应"和"工资溢价效应"实现。城市服务业发展对资本密集型企业和高生产率企业的出口产品质量有更强的促进作用。我们的发现意味着,城市服务业发展对企业出口产品质量的提升具有普遍性,服务业发展与外贸增长方式转型在内涵上是一致的。

This paper studies the impact of the development of urban service industry on the quality of export products. We expand the theoretical framework of Kugler and Verhoogen （2012） and propose ＂Labor- Division Effect＂ and ＂Wage-Premium Effect＂ as the two main mechanisms. At the empirical level, the City Statistical Yearbook is used to match the database of Industrial Enterprise Database and the Customs Database, and the corresponding empirical re- search is carried out in the detailed city-enterprise dimension. Our research shows that the development of urban service industry will help enterprises to im- prove the quality of export products by ＂Labor- Division Effect＂ and ＂Wage- Premium Effect＂. We also find that the development of urban service industry has a stronger effect on the quality of export products for capital-intensive enterprises and high-productivity enterprises. Our conclusion indicates that the development of urban service industry universally promotes the quality of export products and industrial restructuring will promote the transformation of foreign trade growth mode.
