数字化发展、空间溢出与科技金融生态系统共生

Digital Development,Spatial Spillover and Technology and Financial Ecosystem Symbiosis

数字化的不断发展为推进科技金融生态系统成员间的深度合作、强化科技金融生态系统共生关系提供了新契机。将空间因素纳入数字化水平与科技金融生态系统共生关系研究中,从理论层面系统阐释数字化水平对科技金融生态系统共生的作用机理以及空间溢出效应。在此基础上,以2003—2020年中国31个省份的面板数据为研究样本,采用空间杜宾模型,从静态和动态视角实证检验数字化发展对科技金融生态系统共生的影响程度以及空间溢出效应。结果表明:数字化水平对科技金融生态系统共生的影响存在显著的空间溢出效应,即相邻省份数字化水平对本地区科技金融生态系统共生水平起到先抑制后促进的U型非线性影响。数字化水平对科技金融生态系统共生的影响存在显著的区域异质性。

The continuous development of digitalization provides a new opportunity to promote the deep cooperation among members of the sci-tech financial ecosystem and strengthen the symbiotic relationship of the sci-tech financial ecosystem.Incorporate spatial factors into the research on the symbiosis relationship between the level of digitalization and the sci-tech financial ecosystem,and systematically explain the role mechanism and spatial spillover effect of the level of digitalization on the symbiosis of the sci-tech financial ecosystem from the theoretical level.Taking the panel data of 31 provinces in China from 2003 to 2020 as the research sample,the paper empirically tests the impact of digital development on the symbiosis of the sci-tech financial ecosystem and the spatial spillover effect from the static and dynamic perspectives using the spatial Dubin model.The results show that there is a significant spatial spillover effect on the influence of digitalization level on the symbiosis of the sci-tech financial ecosystem,that is,the digitalization level of neighboring provinces has a U-shaped nonlinear effect on the symbiosis level of the sci-tech financial ecosystem in this region,which is first suppressed and then promoted.There is significant regional heterogeneity in the impact of digital level on the symbiosis of the sci-tech financial ecosystem.
