中文摘要：

本文基于2000—2007年工业企业数据库和海关数据库,通过对已有企业层面进口产品质量测算方法的改进,从进口产品质量角度研究了我国进口促进政策与创新驱动发展战略之间的关系及其内在传导机制。研究发现：从一般贸易的进口来看,进口中间品质量的提升显著促进了企业创新,进口资本品质量的提升对企业创新的影响表现为倒U型;技术溢出和市场扩大是企业进口产品质量促进创新的两个显著性路径,但是,降低生产成本路径不是影响企业创新的显著性路径;进口产品质量的提升显著增加了企业持续创新的时间。本文的政策启示是：中国实施进口促进政策具有合理性,实施积极的进口贸易政策对国家创新驱动发展战略具有积极的促进作用。
