摘要
人口老龄化是当前中国面临的挑战,能够对产业结构升级产生重要影响。基于长江经济带11省市2009—2019年的省级面板数据,实证研究人口老龄化、技术创新与产业结构升级的关系。结果表明:人口老龄化对产业结构高级化和产业结构合理化产生积极影响;当以技术创新作为门槛变量时,人口老龄化与产业结构升级的关系呈现单门槛特征,在技术创新跨越门槛值后,人口老龄化的正向作用变得更强。
Population aging is a challenge for China at present,and it can have an important impact on the upgrading of industrial structure.Based on the provincial panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2009 to 2019,the relationship between population aging,technological innovation and industrial structure upgrading is analyzed.The results show that the aging of the population can have a positive impact on the upgrading of the industrial structure.When technological innovation is used as the threshold variable,the relationship between population aging and industrial structure upgrading presents a single threshold feature.After the threshold value is crossed,the positive effect of population aging becomes stronger.
