    摘要:

    数字经济已成为不可逆转的发展趋势,国家层面积极倡导数字经济相关产业的集群化发展。鉴于广东省在全国数字经济发展中占据领先地位,探究不同层次的产业集聚水平与知识溢出效应对广东省数字经济企业创新能力的具体影响及其作用机理,具备深厚的实践意义。依托于上市企业数字经济专利数据与广东省各地级市的经济指标,运用门限回归模型及空间杜宾模型进行深入剖析,得出结论:数字经济产业的集聚水平对企业创新能力展现显著的单一门限效应,二者之间的关系呈现出倒“U”形态势;数字经济企业的创新能力呈现鲜明的空间集聚特性,且知识溢出效应对企业创新能力的提升具有显著的正面推动作用。

    Abstract:

    Digital economy has become an irreversible development trend, and the national level actively advocates the cluster development of digital economy related industries. Given that Guangdong Province occupies a leading position in the development of digital economy in China, it is of profound practical significance to explore the specific impact and mechanism of different levels of industrial agglomeration and knowledge spillover effect on the innovation ability of digital economy enterprises in Guangdong Province. Based on the digital economy patent data of listed enterprises and the economic indicators of prefecture-level cities in Guangdong Province, threshold regression model and spatial Durbin model were applied to conduct in-depth analysis. The research conclusions are as follows. The agglomeration level of digital economy industry shows a significant single threshold effect on the innovation ability of enterprises, and the relationship between the two shows an inverted “U” shape. The innovation capability of digital economy enterprises presents a distinct spatial agglomeration characteristic, and the knowledge spillover effect has a significant positive promoting effect on the improvement of enterprise innovation capability.
