数字服务贸易网络与企业技术持续创新——基于我国沪深A股上市公司的经验证据

Digital Service Trade Network and Continuous Innovation of Enterprise Technology:Based on Empirical Evidence of A-share Listed Companies in China's Shanghai and Shenzhen Stock Exchanges

选取2012—2022年沪深A股上市公司数据,对数字服务贸易网络与企业技术持续创新的关系进行研究。同时,采用基准回归模型、中介模型、门槛模型的方法进行实证,研究表明,数字服务贸易网络对企业技术持续创新具有正向推动作用,且知识产权保护与研发要素流动在二者间发挥中介作用;受知识产权保护与研发要素流动影响,数字服务贸易网络对企业技术持续创新的推动作用呈现非线性特征。基于此,提出提高数字服务贸易领域对外开放水平、建立健全知识产权保护体制机制、发挥研发要素协同配置效应的政策建议,以期为企业技术持续创新注入新动能。

Select the data of A-share listed companies in Shanghai and Shenzhen from 2012 to 2022,this study investigates the rel-ationship between digital service trade networks and innovation sustainability.Using benchmark regression models,mediation models,and threshold models,it is found that digital service trade networks have a positive promoting effect on sustainable technological innovation in enterprises,and intellectual property protection and R&D factor flow play a mediating role between the two.The basic conclusion is that the promotion effect of digital service trade networks on sustained technological innovation of enterprises is non-linear,influenced by int-ellectual property protection and the flow of research and development factors.Based on this,policy recommendations are proposed to improve the level of openness in the field of digital service trade,establish a sound intellectual property protection system and mechanism,and leverage the collaborative allocation effect of research and development factors,so as to inject new momentum into the sustained technological innovation and development of enterprises.
