摘　　要：基于发明专利和实用新型专利数据,运用赫芬达尔指数测量企业专利的知识离散度,以130家高科技上市公司为样本,对两类专利的数量、知识离散度与企业绩效的关系进行实证研究,发现:两类专利的数量对企业绩效均无显著影响;两类专利的知识离散度对企业绩效的影响相反:发明专利的知识离散度对企业绩效有正向影响,实用新型专利的知识离散度对企业绩效有负向影响。Using 130 high-tech listed companies as sample, this paper empirically tested the relationship between patent quantity, patent knowledge dispersion of the invention and utility model patents and firm performance. The corporate patent knowledge dispersion was measured by Herfindahl index based on the invention and utility model patents data. The result shows that the quantities of the two types of patent have no significant effect on the firm performance. It also shows that the knowledge dispersion of the two types of patent has oppo-site effect. Invention patent knowledge dispersion has a positive impact on firm performance, while the utility model patent knowledge dis-persion has a negative impact on firm performance.
