摘　　要：文章将产业政策变化分为渐变和突变两种类型,以我国高技术产业5个分行业1996-2010年的数据为样本,利用分段回归的计量方法,分析了2004年产业政策突变在产业知识生产机制演变中的作用。研究发现,各投入要素的产出弹性均发生了较大变化,其中R&D资金投入具有最高的产出弹性,其贡献率在2004年后得到进一步的提升,国外技术引进从正产出效应转变为负产出效应,而国内技术引进的产出效应则得到较大的提升。This paper divides the industrial policy changes into gradual and sudden changes, and uses the data of five highteeh subindustries from 1996 to 2010 to analyze the role of the sudden industrial policy changes in 2004 in the evolution of industry knowledge production mechanism through subsection regression method. It indicates that the output elasticity of input factors has made great changes; R＆D funding has the highest output elas ticity and its contribution rate has further improved since 2004; the intro duction of foreign technology has shifted from positive to negative output effect,while the output effect of the domestic technology introduction has been raised largely.
