【摘要】 创新产出是提升区域经济发展的重要驱动要素之一.基于河南省2010—2021年18个省辖市的专利面板数据，利用LMDI分解模型（即对数平均迪氏分解模型），定量测度了区域经济结构、区域研发力度、区域创新效率、区域经济发展活动对河南省及其18个省辖市创新产出变化的驱动影响.分析发现：(1)时序上，四个驱动效应对创新产出均起正向推动作用，其中区域经济发展活动是推动创新产出增长的主要驱动效应，贡献率48.51%；区域研发力度效应、区域创新效率效应和区域经济结构效应贡献率分别为31.76%、17.94%和1.80%.(2)空间上，各市域的创新产出存在显著差异且差异逐渐拉大.郑州市的创新产出处于领先地位，总体格局在空间上呈“一超多强”和“梯次分布”的分布特征.(3)经济结构效应和创新效率效应呈“北高南低、东高西低”的空间格局；经济发展活动效应和研发力度效应呈“C”字形分布格局.(4)省域层面的四个驱动效应对各市创新产出变化的影响存在显著差异，其中经济结构效应对郑州、新乡、许昌等地的创新产出起主要促进作用，创新效率效应对郑州、焦作、新乡、开封等地的创新产出起主要促进作用，经济发展活动效应对郑州、洛阳、新乡、许昌等地的创新产出起主要促进作用，研发力度效应对郑州、洛阳、南阳等地的创新产出起主要促进作用.据此提出了提升河南创新发展的相关建议和对策.更多还原

【Abstract】 Innovation output is one of the key driving factors for enhancing regional economic development. Based on patent panel data from 18 provincial-level cities in Henan Province from 2010 to 2021,the Logarithmic Mean Divisia Index(LMDI)decomposition model was used to quantitatively measure the driving effects of regional economic structure,regional R&D intensity,regional innovation efficiency and regional economic development activities on the changes of innovation output in Henan Province and its 18 provincial-level cities. The analysis reveals that:(1) In terms of time series,the four driving effects all play a positive role in promoting innovation output,among which regional economic development activities are the primary driving effect,with a contribution rate of 48.51%.The contribution rates of regional R&D intensity effect,regional innovation efficiency effect,and regional economic structure effect are 31.76%,17.94% and 1.80%,respectively.(2) Spatially,there are significant differences in innovation output among different cities,with these differences gradually widening. The innovation output of Zhengzhou is in a leading position,and the overall pattern is spatially characterized by“one super leader and multiple strong cities”and“tiered distribution.”(3) The economic structure effect and innovation efficiency effect show a spatial pattern of“high in the north and low in the south,high in the east and low in the west”. The economic development activity effect and R&D intensity effect display a“C-shaped”distribution pattern.(4) At the provincial level,the four driving effects vary in their impact on innovation output changes in different cities. The economic structure effect primarily promotes innovation output in cities such as Zhengzhou,Xinxiang and Xuchang. The innovation efficiency effect mainly promotes innovation output in cities such as Zhengzhou,Jiaozuo,Xinxiang and Kaifeng. The economic development activity effect primarily promotes innovation output in cities such as Zhengzhou,Luoyang,Xinxiang and Xuchang. The R&D intensity effect primarily promotes innovation output in cities such as Zhengzhou,Luoyang and Nanyang. Based on these findings,relevant recommendations and countermeasures to enhance Henan’s innovation-driven development are proposed更多还原
