摘要
我国正进入人口老龄化时代。老龄化对科技创新产生积极和消极两方面的影响,随着老龄化程度的逐步加深,这两方面的影响此消彼长。从宏观层面看,人口老龄化对科技创新产生的影响呈现出倒U型趋势,即随着老龄化程度加深,对科技创新的影响经历先上升后下降的过程。基于我国省级层面的面板数据,使用工具变量回归、差分GMM和系统GMM方法进行了实证研究,研究结果证实了老龄化对科技创新的倒U型影响,并且发现:发明、实用新型和外观设计3种专利形式的峰值年龄不一样,作为根本性创新代表的发明专利的峰值年龄出现得最早。
China is entering the period of population aging. Aging has two kinds of impact on technological innovation, one is the positive side and the other is the negative side. These two forces perform in the opposite way. From the macro perspective,the impact of population aging on the innovation is in an inverted U type trend,that is,with the aging of population, impact on innovation firstly increases and then decreases. Based on the panel data of Chinese provincial level,this paper uses instrumental variables regression,differential GMM and system GMM methods for the empirical research. The results confirm that impact of aging on innovation is of inverted U type,and that the peak age of invention, utility model and design is not the same,and that invention patent has the earliest peak age as it is typical fundamental innovation.
