摘要
将技术创新过程按照创新程度的高低,由低到高依次划分为纯粹的模仿、创新式模仿、模仿式创新和原始创新4个演化阶段;运用我国专利增长的年度数据,分别以授权专利技术中的发明、实用新型和外观设计,作为技术创新不同演化阶段的代理变量,对我国在转型时期的技术创新演进过程进行了经验分析。时间序列分析表明,近20年来我国的技术创新经历了一个持续的增长过程;从相对增长上看,创新的增长明显高于模仿的增长,这反映了我国正在由以技术模仿为主的时代向以原始创新为主的时代演进。Panel数据的回归分析显示,在模仿与创新与之间存在着明显的互动关系,一方面模仿促进创新,另一方面创新亦促进模仿,二者呈现动态的交互过程。
Using the numbers of inventions, utility models, and designs in granted patents to denote the degrees of original innovation, imitative innovation, and innovative imitation respectively, we dealt with the evolutionary processes of innovation in China. The empirical results of time series analyses showed that there has been a highly persistent growth of innovation in terms of the numbers of granted patent and its subdivisions in China since 1985,and the regressive analyses of a panel data from 1998 to 2005 gave the mutual dynamic relationships of action and retroaetion between innovation and imitation, And a duralive expansion of inventions aceompanying with an adverse movement of utility models in the percentage components of granted patents exists which reflects a continuous enhancement of innovation relative to imitation in China the latast decade.
