中文摘要：

科学、客观评价我国企业技术创新主体地位发展程度是非常重要的。基于国家创新系统、创新过程理论等,构建了学习再造-价值再造-结构再造（LVS）系统分析框架及其评价指标体系,对2000-2012年我国企业技术创新进行了实证分析。结果表明,我国企业技术创新的结构再造力提升最为突出,价值再造力有持续、大幅提升,学习再造力有提高但存在薄弱环节,总体上企业技术创新主体地位有大幅度提升,其TII指数增长了49.8%。结构分析表明,大型企业特别是民营大企业对提高企业技术创新主体地位作用最大。最后,提出了几点政策建议。

英文摘要：

It is important to carry out a scientific and objective analysis of the core position of technology innovation in China＇s enterprises. Based on the theory of national innovation system and innovation process,this paper constructs a systematic analysis framework of learning reengineering,value reengineering and structure reconstruction（ LVS） and its evaluation indexes,and then applies the technology innovation index of enterprise（ TII） to analyze dynamically the technology innovation activities of China＇s enterprises from 2000 to 2012. The empirical analysis results show that the ability of structure reconstruction is the most prominent,the ability of value reengineering has achieved a continuous and rapid increase,and the ability of learning reengineering is relatively high but with some weaknesses. Generally,the core position of technology innovation of China＇s enterprises has been promoted rapidly,and specifically,the TII index has been increased by 49. 8%. It is also shown by a structural analysis that large firms,especially private firms,have played a more important role to promote the core position of technology innovation in China＇s enterprises. Finally,some policy suggestions are put forward in this paper.
