摘要
在对我国上市公司专利的数量和类型刻画的基础上,考察了R&D活动对企业价值和业绩的影响,研究发现:R&D活动能为企业创造价值,其中R&D投资能提高企业价值和经营业绩;目前上市公司的专利创新程度不高,发明专利的数量少于非发明专利数量;尽管专利拥有量能提高企业价值,专利数量越多,对企业价值的贡献越大,但不同质量的专利对企业业绩有不同贡献,创新程度较高的发明专利能显著提高企业业绩,创新程度较低的其他类型专利却不能有效地为企业创造价值;在目前我国创新相关机制不完善的环境下,市场还不能有效甄别不同类型的专利.
On the depiction of the quantities and types of patents of Chinese listed companies, it investigates the influence of R&D activities on firm value and performance. The results show that R&D activities can create value for the enterprises. R&D input can increase firm value and performance. At present time, the patents of Chinese Xist companies have rather low innovation. Invention patents are less than non-invention patents. Although patents can improve firm value, and the more patents, the greater contribution, the different quality of patents have different contributions to per- formance. The invention patents with more innovation can significantly increase firm performance while non-invention patents can't effectively create value for enterprises. Under current circumstances, the mechanisms related to innovation are not sound, and the market can't screen the quality of patents.
