黄河流域绿色创新的时空演化特征及影响因素分析
Spatiotemporal evolution characteristics and influencing factors of green innovation in the Yellow River Basin
摘要
Abstract
This study uses green patent data to characterize green innovation by taking 89 prefecture-level and above cities in the Yellow River Basin of China from 2005 to 2020 as the research object.It employs a standard deviation ellipse and spatial autocorrelation to unveil green innovation's spatial and temporal evolution pattern.In addition,it uses a spatial Durbin model to analyze the factors influencing green innovation and decompose the spatial effects of various factors.The results indicate that:(1)green innovation in the Yellow River Basin and its upstream,midstream,and downstream areas demonstrate a rapid development trend.(2)The standard deviation ellipse of green innovation reveals a"northeast-southwest"distribution pattern with stable parameters.The center of gravity exhibits a moving pattern of"first east and then west".(3)Global spatial autocorrelation of green inno-vation is evident,with local spatial autocorrelation primarily characterized by high-high and low-low patterns.(4)Science and technology investment substantially positively impacts green innovation.The full-time equivalent of urban research and experimental development personnel and the proportion of the tertiary industry exhibit a sub-stantial negative spatial spillover effect.Conversely,the number of books in public libraries and the green cover-age of built-up areas demonstrate a substantial positive spatial spillover effect.(5)Science and technology invest-ment has the strongest positive effect of promoting green innovation in the upper reaches.The upgrading of indus-trial structure substantially promotes the development of green innovation in the middle reaches.Simultaneously,social culture plays a strong positive role in advancing green innovation in the lower reaches.关键词
