摘要
绿色创新效率作为“创新驱动”和“绿色发展”的融合,是中国推动可持续发展的重要手段,也是发展新质生产力的重要内容,在中国老龄化程度不断加深的背景下,研究人口老龄化对绿色创新效率的影响具有重要意义。文章基于2005~2019年中国30个省份的面板数据,利用Super-SBM模型对中国的绿色创新效率进行测度,并建立空间计量模型实证检验人口老龄化对中国绿色创新效率的影响。研究发现:中国的绿色创新效率仍处在较低的水平,在研究时间范围内呈现波动上升趋势,东部地区的绿色创新效率最高,西部、中部地区次之,东北地区最低。人口老龄化对中国的绿色创新效率的影响呈现先升后降的倒“U”型曲线关系,在人口老龄化初期,人口老龄化会促进绿色创新效率的提升,随着人口老龄化程度的进一步加深,人口老龄化将对绿色创新效率起到抑制作用,人口老龄化对邻近地区的影响也呈现这种倒“U”型曲线关系。人口老龄化对绿色创新效率的影响存在空间异质性。当前大部分省份处在“老龄化社会”末期或者“老龄社会”初期,人口老龄化对绿色创新效率的影响在倒“U”型曲线的顶点附近,各省份要抓住机会窗口期,在人口老龄化进一步加深之前,充分开发老年人力资源,发挥老年人口的知识技能和经验积累等优势,提高绿色创新效率。
Green innovation efficiency,as the integration of“innovation driven”and“green development”,is an im⁃portant means of promoting sustainable development in China,and also an important content of developing new quality productivity.Against the backdrop of the deepening aging population in China,studying the impact of population aging on green innovation efficiency is of great significance.Based on the panel data of 30 provinces in China from 2005 to 2019,this paper uses the Super-SBM model to measure the efficiency of green innovation in China,and establishes Spatial Econometric Model to test the impact of population aging on green innovation in China.The research finds that the efficiency of green innovation in China was still at a relatively low level,showing a fluctuating upward trend within the research time frame.The efficiency of green innovation is highest in the eastern region,followed by the western and central regions,and lowest in the northeast region.The impact of population aging on China’s green innovation efficien⁃cy shows an inverted U-shaped curve relationship of first increasing and then decreasing.In the early stage of popula⁃tion aging,the population aging will promote the improvement of green innovation efficiency,while the further deepen⁃ing of population aging,the population aging plays an inhibitory role on the efficiency of green innovation,and the spa⁃tial spillover effect of population aging on adjacent areas also presents an inverted“U”curve relationship.There is spa⁃tial heterogeneity in the impact of population aging on the efficiency of green innovation.Currently,most provinces are in the late stage or early stage of an“aging society”,and the impact of population aging on green innovation efficiency is near the apex of the inverted“U”curve.Each province should seize the opportunity window period,fully develop el⁃derly human resources,leverage the knowledge,skills,and experience accumulation advantages of the elderly popula⁃tion,and improve green in
