摘　　要：现有关于南北经济差距的研究大多从产业结构、发展环境等角度进行解释,而对科技创新的影响关注不多。基于2004-2019年282个地级市面板数据,采用双向固定效应模型进行了实证分析,研究发现:(1)科技创新差异是导致南北经济差距的主要原因;科技创新对经济发展的驱动作用在南方更强;(2)南北科技创新驱动作用差异并非由头部大城市发展差距导致,而是由地区整体发展差距导致;(3)无论是实质性创新还是策略性创新,南方的科技创新驱动作用都显著强于北方。Most existing studies on North-South economic disparity are explained from the perspective of industrial structure and development environment,and little attention is paid to the role of technological innovation.Based on the panel data of 282 Chinese City⁃level cities from 2004 to 2019,this paper uses two⁃way fixed effect model to conduct an empirical study.The results show that:(1)the difference in technological innovation is the main reason for the economic disparity between North and South;The driving force of technological innovation on economic development is stronger in the South;(2)The difference in driving force of technological innovation between North and South is not caused by the development gap of the metropolis in the two regions,but by the overall development gap;(3)Whether it is substantive innovation or strategic innovation,the driving force of technological innovation in the South is significantly stronger than that in the North.
