摘　　要：基于A股上市公司数据,采用多时点双重差分法,实证检验国家知识产权优势企业认定对企业市场价值的影响。研究发现,国家知识产权优势企业认定显著提高了企业市场价值,且主要通过增加股权融资、促进技术创新及降低企业面临的制度性交易成本来实现。分样本回归发现,这一认定的价值提升效应在非国有企业、成长期企业及知识产权保护水平较高的地区中更加明显。进一步分析表明,国家知识产权优势企业认定具有显著的行业示范效应。此外,与国家知识产权示范城市建设相比,国家知识产权优势企业认定的市场价值提升效应更为显著,且二者较好地发挥了政策的协同效应。Based on the data of Chinese A-share listed companies,this study uses the multi-time point difference in difference method to test the effect of national intellectual property advantage enterprises identification on the enterprises market value.It shows that national intellectual property advantage enterprises identification significantly improves the enterprises market value,which is mainly achieved by increasing equity financing,promoting technological innovation and reducing the institutional transaction costs.According to the sub-sample regression,the value enhancement effect of national intellectual property advantage enterprises identification is more obvious in non-state-owned enterprises,growing enterprises and areas with higher intellectual property protection level.Further analysis shows that the national intellectual property advantage enterprises identification has significant industrial demonstration effect.In addition,compared with the national intellectual property demonstration city construction,national intellectual property advantage enterprises identification has a more significant effect on the enterprises market value,and the two policies have produced the synergistic effect.
