报告摘要:The number of patent filings is an important proxy of a country’s innovation capability. In this field, China has become the world’s No.1 since 2011 and its lead keeps widening. According to the World Intellectual Property Organization, China filed 1.4 million patents in 2019, which is more than twice that of the USA and accounted for 43.4% of the world’s total. However, this paper documents a negative relationship between a Chinese listed firm’s Tobin Q and the number of its patent filings. We further find that such a counter-intuitive relation can be explained by firms’ motivation to over-report their intangible assets via more patent fillings, which is not recognized by the market. We find evidence supporting firms’ regulatory arbitrage behaviors: firms have incentives to file more patents when they strive for the InnoCom (“High-tech Enterprise Certification”) at the cost of patent quality.
专利申请量是衡量一个国家创新能力的重要指标。在这一领域,自2011年以来,中国已成为世界第一,并不断扩大领先优势。根据世界知识产权组织的数据,2019年中国申请专利140万件,是美国的两倍多,占世界总量的43.4%。然而,本文证明了中国上市公司的托宾Q与其专利申请量之间存在负相关关系。我们进一步发现,这种反直觉的关系可以用企业通过更多的专利申报来过度报告其无形资产的动机来解释,而这并没有得到市场的认可。我们发现了支持企业监管套利行为的证据:当企业以专利质量为代价争取InnoCom(“高新技术企业认证”)时,企业有动力申请更多的专利。
