Temporal and Spatial Pattern Evolution of China's Digital Innovation and Multidimensional Analysis of Driving Forces:From the Perspective of Digital Economy Patent Application
Based on the panel data of 251 cities in China from 2000 to 2020,this paper studies the spatial-temporal pattern evolution and driving factors of digital innovation in China with the help of the center of gravity model,standard deviation ellipse and the dynamic spatial panel Durbin model based on common factors.The results show that:1)the spatial distribution of digital innovation in China is"strong in south and weak in north,high in east and low in west",and the imbalance in east and west is less than that in south and north;The spatial distribution of digital innovation in the northern region showed a"linear-flattening-shrinking"pattern,while that in the southern region showed a"multi-point-circular-expanding"pattern.2)Digital innovation has strong temporal and spatial correlation with technological innovation and digital economy.Among them,the southern region and the central and eastern region are more sensitive to the development of national digital innovation.3)Digital innovation has a technology locking effect in time,and digital innovation in the previous period has a negative impact on the current period.In addition to financial development,factors such as human capital,firm size,market competition,consumer demand,big data resources and government support have greater short-term effects than long-term effects on digital innovation.4)Human capital,firm size,market competition and financial development have a driving effect on digital innovation in the city and neighboring cities;Big data resources and government support can promote the development of digital innovation in the local city,but can inhibit the neighboring city.However,the consumption demand has a restraining effect on the city and the neighboring city.
