摘要
科技创新是新质生产力的核心驱动力,全要素生产率的提升是新质生产力形成与发展的核心标志。基于此,以“量的积累、质的提升、新的拓展”三维向度为目标层,以“劳动者、劳动对象、劳动资料”为准则层,构建新质生产力发展的综合评价指标体系。采用中介效应模型、空间杜宾模型、门限效应模型,探讨新质生产力对全要素生产率的影响路径、空间溢出效应,以及差异性科技创新能力之下的异质性作用。研究发现:新质生产力能促进全要素生产率提升,具有空间溢出效应。进一步研究发现:新质生产力与全要素生产率形成非线性正“U型”关系,即促进作用来源于高水平新质生产力;科技创新在新质生产力对全要素生产率影响中形成中介效应及门限效应;区域层面,新质生产力对全要素生产力的影响呈现明显异质性特征。据此,从培育新质生产力、增强区域科技创新能力等方面,为提升区域全要素生产率提供参考。
Scientific and technological innovation is the core driving force of new quality productive forces.The improvement of total factor productivity is the core symbol of the formation and development of new quality productive forces.Based on this,with the three dimensions of“quantity accumulation,quality improvement and innovative development”as the target layer,and“laborer,labor objects and labor materials”as the criterion layer,a comprehensive evaluation index system for the development of new quality productive forces is constructed.The mediation effect model,the spatial Dubin model and the threshold effect model are used to explore the influence path of new quality productive forces on total factor productivity,the spatial spillover effect,and the heterogeneity effect of the differentiated scientific and technological innovation ability.The study finds that the new quality productive forces can promote the increase of total factor productivity and has spatial spillover effect.Further research finds that the new quality productive forces form a non-linear positive U-shaped relationship with total factor productivity,that is,the promotion effect comes from the high level of new quality productive forces;scientific and technological innovation forms intermediary effect and threshold effect in the influence of new quality productive forces on total factor productivity;at the regional level,the influence of new quality productive forces on total factor productivity presents obvious heterogeneous characteristics.Accordingly,it provides reference for improving regional total factor productivity from the aspects of cultivating new quality productive forces and enhancing regional scientific and technological innovation ability.
