摘　　要：文章基于我国2005-2017年30个省级面板数据,运用空间计量模型和门槛回归模型,实证考察了知识溢出、吸收能力与区域创新之间的关系。研究显示:地理距离、经济距离和技术距离都是影响知识溢出的重要因素,在三种空间因素作用下,各省域间的知识溢出均能够显著促进我国区域创新;知识溢出对区域创新的促进作用要受到吸收能力因素的影响,人力资本和知识产权保护水平的提高有利于知识溢出效应的实现,地区间技术差距的扩大不利于知识溢出效应的实现;门槛效应分析表明,三种吸收能力因素的调节作用均呈现出非线性特征,其中人力资本和技术差距的调节作用具有单一门槛效应,知识产权保护的调节作用具有双门槛效应。为了有效吸收和利用地区间的知识溢出,政府应根据本地区的实际情况优化调整吸收能力因素,实施差异化的区域创新提升策略。Based on the provincial panel data of 30 regions in China from 2005 to 2017,this paper empirically examines the relationship between knowledge spillover,absorptive capacity and regional innovation by using spatial econometric model and threshold regression model. The research shows that geographical distance,economic distance and technological distance are all important factors that affect knowledge spillovers. Under the action of three spatial factors,knowledge spillovers between provinces can significantly promote regional innovation in China;the promotion of knowledge spillovers on regional innovation is affected by absorptive capacity factors. The improvement of human capital and intellectual property protection level is conducive to the realization of knowledge spillovers,while the expansion of technological gap between regions is not conducive to the realization of knowledge spillovers;threshold effect analysis shows that the moderating effects of the three absorptive capacity factors show nonlinear characteristics. Among them,the moderating effects of human capital and technology gap have a single threshold effect,and the moderating effects of intellectual property protection have a double threshold effect. In order to effectively absorb and utilize knowledge spillovers between regions,the government should optimize and adjust the absorptive capacity factors according to the actual situation in the region and implement differentiated regional innovation promotion strategies.
