摘要
文章将大数据综合试验区建设看作是地区数字化变革的准自然实验,构建了大数据综合试验区建设影响城市创新水平的理论框架,利用2009-2019年中国285个地级市和上市公司面板数据,采用双重差分法、三重差分法和有调节的中介效应模型实证检验了大数据综合试验区建设对城市创新水平的影响效应与作用机制。研究发现:大数据综合试验区建设显著促进了城市创新水平;机制检验表明,大数据综合试验区建设通过优化要素配置效率、推动产业结构升级和提升创业活跃度等途径促进城市创新,区域知识吸收能力在上述路径中起到了不同程度的调节作用;异质性检验表明,大数据综合试验区建设的创新促进效应主要体现在民营企业上,而对国有企业创新水平产生了负向影响;大数据综合试验区建设促进了低数字赋能行业创新数量提升而抑制了高数字赋能行业创新数量,提升了高数字赋能行业创新质量而未对低数字赋能行业创新质量产生显著影响。
Under the sweep of the new wave of industrial technology revolution,digital productivity is driving the digital transformation of social production worldwide with unprecedented speed,breadth and depth.In this context,clarifying the profound impact of digital transformation on innovation activities and the underlying mechanism will undoubtedly be beneficial for promoting the development of China's digital economy and the construction and improvement of a data-driven innovation system.In view of this,The article views the construction of Big Data Pilot Zones as a quasi-natural experiment of regional digital transformation.A theoretical analysis framework for the impact of Big Data Pilot Zones construction on urban innovation level is constructed.Based on the panel data of 285 prefecture-level cities and listed companies in China from 2009 to 2019,we empirically tested the impact effects and mechanisms of action of the construction of Big Data Pilot Zone on urban innovation level using double difference method,triple difference method and moderated mediated effect model.It is found that the construction of Big Data Pilot Zones significantly promotes the improvement of urban innovation level,and this finding still holds after the robustness tests such as PSM-DID and instrumental variable method.The mechanism test shows that the construction of Big Data Pilot Zones promotes the improvement of urban innovation level by optimizing factor allocation efficiency,promoting industrial structure upgrading and enhancing entrepreneurial activity,and regional knowledge absorption capacity plays a moderating role to different degrees in the above paths.The heterogeneity test shows that the innovation promotion effect of the construction of the Big Data Pilot Zones is mainly reflected in private enterprises,while it has a negative impact on the innovation level of state-owned enterprises.The construction of the Big Data Pilot Zones promotes the quantity of innovation in low-digital-empowered industries and suppresses the quantity
