摘　　要：基于我国59个创新型城市2009-2015年的面板数据,分析了政府创新投入、企业创新投入和外商直接投资对城市创新能力的影响,并从省会城市和城市规模考察了城市规模等级对政府创新投入和城市创新能力的调节效应。结果显示:政府及企业创新投入对城市的创新能力均具有显著的促进作用,但企业创新投入的贡献度更大;外商直接投资对城市的创新能力有抑制作用;省会城市和城市规模对政府创新投入的城市创新能力效应具有负调节作用,即在中小城市和非省会城市中,政府创新投入对城市创新能力的贡献要大于大城市及省会城市。By using the panel data of 59 innovative cities in China from 2009 to 2015,this essay examines the influences of government innovation input,enterprise innovation input and FDI on urban innovation capability,and analyzes the adjustment function of city size on the government innovation input and urban innovation capability from the provincial capital and city scale. The results show that compared with government innovation input,enterprise innovation input has a greater role in promoting urban innovation capability;FDI has an inhibitory influence on the urban innovation capability;Provincial capital and city scale have a negative adjustment function,that is,in small and medium-sized cities and non-capital cities,the contribution of government innovation input to urban innovation capacity is greater than that of large-scale and provincial capital cities.
