国家创新型城市对属地创新能力影响效应评估——政策动态过程与政企互动视角

选取2003-2016年城市数据样本，基于国家创新型城市分批次确立的特性，采用渐进双重差分模型、固定效应双重差分模型和处理效用双重差分模型，研究国家创新型城市对属地创新能力的整体效应、长期动态效应和批次效应。结合城市创新微观主体构成特性，分析属地国家创新型企业政策及企业类型异质性对属地创新能力的影响。结果显示：国家创新城市对属地创新能力提升在长短期均起到正向促进作用，且越早确立的城市对属地创新能力提升的作用效果越显著；国家创新型企业政策对城市创新能力提升起到正向调节作用，且企业集团作用大于上市公司和一般企业。最后，提出创新型城市建设相关政策建议。
