数字创新合作、应用鸿沟与区域间共同富裕

Digital Innovation Cooperation,Application Gap,and Interregional Common Prosperity

数字应用鸿沟是指地区在数字社会中参与和应用能力上的差异。数字化飞速发展背景下,数字应用鸿沟可能会造成新的贫富分化。地区间数字创新合作是缩小数字应用鸿沟,促进共同富裕的重要举措。文章手工整理了2013—2019年中国城市数字技术专利联合申请数据,以此为基础检验了数字技术研发合作创新能否从提高数字应用能力方面推动中国区域间共同富裕。研究发现:第一,数字创新合作显著提升了居民收入水平,这一提升效应对中西部地区更为有效。第二,机制研究发现,数字创新合作能通过提升数字应用能力而促进居民收入水平增长,且对中西部地区的提升大于东部地区。第三,微观主体数字关注度正向影响数字创新合作对地区数字应用能力的提升效应,其影响效应随主体不同而具有异质性,政府数字关注度偏向影响数字发展能力,公众数字关注度偏向影响数字致富机会。第四,共享效应研究发现,数字创新合作关系具有共享溢出效应,可以弥合地区间数字应用鸿沟,进而缩小贫富差距,实现共享发展。文章不仅为数字创新合作与共同富裕的关系提供了经验证据,并从缩小数字应用鸿沟视角探讨了这一关系的内在机制,为缩小数字鸿沟,实现共同富裕提供了政策启示。

Against the backdrop of the digital wave sweeping across the world,the digital application gap may lead to new wealth disparities.The digital application gap refers to the differences in regional participation and application capabilities in the digital society.The innovation cooperation of digital technology between regions is an important measure to narrow the digital application gap and promote common prosperity.This paper examines from the perspective of digital application gap whether collaborative innovation in digital technology research and development can promote common prosperity between regions in China by improving digital application capabilities.By manually collecting data on joint patent applications for digital technology in Chinese cities from 2013 to 2019,this paper investigates the impact of digital innovation cooperation on household income levels and interregional income disparities.The study shows that:First,digital innovation cooperation significantly improves household income levels,which is more effective for western regions.In regions with a high level of digital development,digital innovation cooperation has a greater impact on income enhancement,indicating that the digital development level has a supportive effect on the transformation of digital innovation cooperation results;the spillover effect of industry-university-research cooperation is significant,and its improvement effect on regional income is relatively stronger.Second,digital innovation cooperation promotes the growth of household income levels by enhancing digital application capabilities,and the improvement effect in central and western regions is greater than that in eastern regions.Third,the digital attention of micro-subjects positively regulates the improvement effect of digital innovation cooperation on regional digital application capabilities.This regulatory effect varies depending on the subject:Government attention tends to regulate digital development capabilities,while public digital attention tends to regulate digital wealth generation capabilities.Fourth,digital innovation cooperation has a shared spillover effect,which can bridge the digital application gap between regions,thereby narrowing the wealth gap and achieving shared development.This paper not only provides empirical evidence for the relationship between digital innovation cooperation and common prosperity,but also explores the internal mechanism of this relationship from the perspective of narrowing the digital application gap,providing policy inspiration for narrowing the digital application gap and achieving common prosperity.
