数字金融与区域创新差距

Digital Finance and Regional Innovation Gap

数字金融作用于区域创新发展路径,对推动区域创新均衡协调发展具有重要意义。结合北京大学数字普惠金融指数、省市级宏观数据和上市公司等多维度数据,基于泰尔指数、基尼系数和阿特金森指数测度了区域创新发展差异,多方位考察数字金融指数及数字覆盖范围、使用程度、支持服务力度与区域创新差距之间的关系,并探索数字金融影响区域创新差距的传导机制和微观基础。研究发现,数字金融的发展有利于缩小省内各地级市间的创新差距,并且数字金融的普惠效应在东部地区和省份内部创新差异较小的地区更强。进一步的传导机制分析表明,数字金融能够促进传统金融与信息基础设施的有效结合,提高信息基础设施对区域创新差距的边际影响。但值得注意的是,数字金融并不能显著推动省份之间创新的均衡化发展。微观分析结果表明,数字金融能够缩小企业间创新差距,但是不利于东部和中西部地区之间创新的均衡化发展。因此要进一步深化数字金融发展,实施差异化的发展策略,为区域创新的平衡发展提供强劲动力。研究结论不仅能够为推动区域技术创新、缩小地区创新差距提供理论基础,还可以为区域协调发展提供一定的启示。

Based on advanced digital technology,digital finance has influenced the development path of innovation in different regions,which is of great significance for promoting the improvement of regional technological innovation level and realizing the balanced and coordinated development of regional technological innovation.In order to identify the important role of digital finance in regional development,combining with multi-dimensional data such as Peking University’s Digital Financial Inclusion Index,provincial and municipal macro data and listed company data,the regional innovation development differences are measured by using the Theil Index,the Gini Coefficient and the Atkinson Index,and from the perspective of inter-provincial and intra-provincial differences,the relationship amon g digital finance index,digital coverage,digital use degree,digital support service strength and regional innovation gap is investigated in many aspects.At the same time,the heterogeneity effect of digital finance on regional innovation gap under different regions and different innovation levels are tested,and the specific transmission mechanism and micro foundation of the influence of digital finance on regional innovation gap are explored.The research results show that digital finance has a reverse inhibitory effect on regional innovation differences,that is,the development of digital finance is conducive to reducing the innovation gap among prefecture-level cities within the province and realizing the balanced development of innovation among cities,and passing the robustness test of instrumental variables and substitute variables.At the same time,the inclusive effect of digital finance is relatively more obvious and stronger in the eastern region and the regions with small innovation differences within the province.Further analysis of the transmission mechanism shows that digital finance can promote the effective combination of traditional finance and information infrastructure,increase the marginal impact effect of information infrastructure on regional innovation gap,and then play a role in the balanced and coordinated development of regional innovation.However,it is worth noting that,for different provinces,digital finance does not significantly promote the balanced development of innovation among provinces.In addition,the results of micro enterprises show that digital finance can not only help improve the technological innovation level of enterprises,but also help alleviate the innovation gap among enterprises,but it is not conducive to the balanced development of innovation between the eastern and other regions.Therefore,it is urgent to pay more attention to the development of digital finance,further deepen the development level of digital finance in an all-round way,implement differentiated dynamic development strategies,encourage developed regions to actively help the development of digital finance in backward regions,make full use of the“digital dividend”role of digital finance in alleviating the regional innovation gap,and provide strong driving force support for the balanced and coordinated development of regional innovation.On the one hand,the research conclusion can provide a strong starting point of digital finance for strengthening regional technological innovation level and improving regional technological innovation gap;On the other hand,it can also provide certain theoretical guidance and thought inspiration for regional balanced and coordinated development.
