文章基于产业集聚的专业化和多样化理论,利用1997—2011年高技术产业统计数据,计算了中国高技术产业区域专业化和多样化的动态变化情况,验证了专业化和多样化对区域创新绩效的影响。结果显示,专业化抑制了高技术产业区域创新活动,多样化促进了高技术产业区域创新活动。相应政策含义是,高技术产业集聚区应鼓励多种产业共同发展,多样化的环境有利于知识外溢和交流,从而提高产业创新水平。 Based on the specialization and diversification theory of industrial agglomeration, the article calculated the dynamic changes of specialization and diversification of high-tech industry in China from 1997 to 2011 with the statistics of high-tech industry, and verified the specialization and diversification of regional innovation Impact of performance. The results show that specialization has inhibited the innovation activities in high-tech industries and diversified the innovation activities in high-tech industries. The corresponding policy implies that the high-tech industrial cluster should encourage the common development of various industries, and the diversified environment is conducive to spillover and exchange of knowledge so as to raise the level of industrial innovation.
