本文基于中国1985-2010年省级专利数据的研究发现, 在中国专利数量激增的背后, 专利的总体创新含量并未得到与之相称的提高。我们发现专利激勸政策是造成这一现象的重要原因, 专利激励政策显著促进了专利申请数和授权数的提高。但是从对以专利授权率、撤回率和续期率作为代理变量的专利质量影响的经验研究结果看: 一方面, 专利激励政策显著降低了企业的专利平均质量; 另一方面, 通过对不同专利类型的进一步研究, 我们还发现专利质量并未受到激励政策的显著影响, 专利激勘政策的作用主要体现在企业专利中占比最大的实用新型和外观设计专利上, 并且, 在加入更多控制变量、重新构建被解释变量等检验后, 该结论依然稳健。
