| 运用2011-2018年我国31个省级面板数据和北京大学编制的普惠数字金融指数，实证检验了数字金融对于我国区域创新效率的影响效应。研究发现：数字金融能够显著提升我国区域创新效率；从数字金融维度上来看，数字金融的覆盖广度和使用深度对于区域创新效率的促进作用显著，但是数字金融的数字化程度对于区域创新效率的促进作用不显著；分区域来看，数字金融对于东部地区的促进作用要优于中西部地区，覆盖广度对于东部地区的促进作用要优于使用深度，而中西部地区正好相反；数字金融对于区域创新效率的影响存在基于地区市场化程度和互联网普及率的单门槛效应，数字金融对于区域创新效率的促进作用只有在跨越相应的门槛值后才能发挥作用，而且该作用随着门槛变量水平的提高而逐渐增大。 |

| Based on the panel data of 31 provinces in China from 2011 to 2018 and the inclusive digital finance index compiled by Peking University,this paper empirically tests the impact of digital finance on regional innovation efficiency in China. It is found that the digital finance can significantly improve the efficiency of regional innovation. From the perspective of digital finance,its coverage and depth can significantly promote regional innovation efficiency while the digitization degree can not. In terms of regions,digital finance plays a better role in the eastern region than in the central and western regions,and the breadth of coverage has a better effect than the depth of use in the eastern region,while it is just opposite in the central and western regions. The impact of digital finance on regional innovation efficiency has a single threshold effect based on regional marketization degree and internet penetration rate. The promotion effect can only be achieved after crossing the corresponding threshold values,and this effect gradually increases with the improvement of threshold variable level. |
