本文将受知识产权保护制度约束的模仿效应参数及模仿成本引入Hausman的技术水平模型,通过建立1994—2009年SITC Rev.3的三位编码产品与中国国民经济中35个工业行业的对应关系,构建了行业出口技术水平测算指标,运用固定效应模型与系统GMM估计方法,实证分析了知识产权保护对行业出口技术进步的影响及在不同行业间的差异性体现。研究结果表明：中国知识产权保护制度的完善对出口技术提升起到了加速器的作用,但并未对出口规模扩张做出显著直接贡献,而是通过影响出口技术间接作用于出口规模;不同行业的知识属性差异使知识产权保护的出口技术进步效应在研发强度大、技术水平高、外资渗透率高的行业中更显著。

The imitation effection parameter and the cost restricted by intellectual property protection are introduced into Hausman model. Through establishing the corresponding relationship of the three code SITC Rev.3 products and 35 industrial sectors in 1994--2009, we construct the technology index of industry export. Using the fixed effects model and the system GMM estimation methods, this paper empirically analyzes the effect of on the technological progress of export, and the differences among different industry. Some conclusions can be concluded： The improvment of China＇s IPR has promoted the technical level but not the quantitative expansion of the export; There is an indirect positive effects between IPR and export scale; The knowledge discrepancy of industries attributes to the difference of this effection, which may be more significant in industries with high R＆D intensity, level of technology and foreign investment.
