金融发展、空间关联与区域创新异质性——基于空间杜宾模型(SDM)的经验证据

Financial Development、Spatial Correlation and Regional Innovation Heterogeneity——Empirical Evidence Based On the Spatial Dubin Model

本文利用2000～2016年30个省的面板数据,检验金融发展对区域创新的影响。通过构建空间杜宾模型(SDM),以厘清金融发展与地区技术创新活动之间的空间互动效应,并从时间序列、地区板块和专利层次三大角度切入,深入研究金融发展对区域技术创新的影响。研究表明,金融发展的技术创新产出效果存在显著的异质性。具体来看,初期阶段的东、中部地区,金融发展的目标导向并不在于推进技术创新,历经经济发展转型后,这类地区的金融发展对区域技术创新展现出了较强的驱动作用,而西部地区由于自身创新底蕴不足和金融发展缺欠等原因,无法对高端技术创新活动产生裨益。从空间关联来看,就技术创新活动的特性来看,周边金融发展的带动所能引致的创新产出十分有限,甚至还有着一定吸纳本地技术创新资源,不利于技术创新活动的症结,这也暗含着当前金融发展的竞合行为仍存在一定的优化空间。本文的研究结论有助于优化区域金融资源配置,提高地区的技术创新动能。

This paper examines the influence of financial development on regional innovation by applying the panel data from 30 Chinese provinces from 2000 through 2016.An in-depth study is made of the said influence by constructing a Spatial Dubin Model(SDM)to clarify the spatial interaction between financial development and regional technological innovation activities,and considering the issue from the three perspectives of time series,regional sections as well as patent levels.The results show that the effects of financial development in terms of technological innovation output are significantly heterogeneous.More specifically,in the early stages of development of the eastern and central regions,the initial goal of financial development was not to promote technological innovation.However,with the economic growth and transformation in those regions advancing,the financial development therein was later turned into a driving force for the technological innovation efforts in the regions.On the other hand,the western region,unfortunately,fails to facilitate the high-end technological innovation activities,for the weak background in technological innovation and the poor strength in financial development in the region.From the perspective of spatial correlation,it can be seen that the innovation output likely to be induced by the financial development in the surrounding areas is very much limited,for the characteristics of technological innovation activities.There even exists a certain degree of absorption of the local technological innovation resources,which is certainly not conducive to the advancement of technological innovation activities in the region.The presence of all the phenomena reveals that there is much room for work towards the optimization in the current competitive financial development,as this paper concludes.The findings of the study are expected to be of help to an informed decision on a more rational allocation of the regional financial resources,hence improving the technological innovation momentum in the region.
