摘要
数字和创新是未来全球经济增长的两个关键要素,本文尝试研究宏观数字经济对微观企业创新绩效的影响。在理论分析的基础上,采用python软件收集赛迪网发布的城市经济指数作为衡量城市数字经济发展水平的指标,基于2017—2020年我国沪、深两市A股上市公司数据进行实证检验。研究结果表明,数字经济发展会显著提升企业创新绩效,这一结论在一系列稳健性检验后仍然成立。异质性检验表明,在省会城市、民营企业和大中型企业,数字经济对企业创新绩效的影响程度会更大。中介效应模型表明,数字经济通过优化市场效率,增强企业债务融资能力、促进企业结构升级,进而提高企业创新绩效水平。本文的研究丰富了数字经济和企业创新绩效的相关理论研究,也强化了数字经济的微观作用机理,对如何提升企业创新绩效水平、促进经济高质量发展具有一定的现实意义。
Digital and innovation are the two key elements of future global economic growth.This paper attempts to study the impact of macro digital economy on micro enterprise innovation performance.On the basis of theoretical analysis,Python software is used to collect the urban economic index released by CCID as an index to measure the level of urban economic development.This paper conducts an empirical test using the data of A-share listed companies in Shanghai and Shenzhen from 2017 to 2020.The research conclusion shows that the development of digital economy can significantly improve the enterprise innovation performance,and this conclusion is still valid after a series of robustness tests.The heterogeneity test shows that in provincial capital cities,private enterprises and large and medium-sized enterprises,the impact of digital economy on enterprise innovation performance is stronger.The intermediary effect model shows that digital economy improves the level of enterprise innovation performance by optimizing market efficiency,enhancing enterprise’s debt financing capacity and promoting enterprise structure upgrading.This research enriches the relevant literature research on digital economy and enterprise innovation performance,and strengthens the micro mechanism of digital economy.The research also has certain practical significance on how to improve the level of enterprise innovation performance and promote high-quality economic development.
