基于因子分析和聚类分析的河南省城市技术创新能力评价研究

Evaluation of Urban Technological Innovation Capability in Henan Province Based on Factor Analysis and Cluster Analysis

【目的】构建河南省城市技术创新能力评价指标体系,助力河南省提升整体技术创新能力。【方法】采用因子分析和聚类分析方法,选取了R&D活动人员、用于科技的财政支出等14个指标,并从技术创新投入能力、技术创新效益能力、技术创新潜在能力三个方面,构建河南省18个城市的技术创新能力评价指标体系,对河南省18个城市技术创新能力进行评价研究。【结果】通过设定投入创新绩效因子和创新潜在因子,以各个因子的方差贡献率与累计贡献率的比值作为权重,得出综合得分,并对各个城市的技术创新能力进行排名。然后通过系统聚类,将河南省18个城市分为五类。【结论】提出河南省各市应加大政策扶持、鼓励创新创业、加强人才引进和科技创新投入,城市之间应加强合作、促进产业发展等政策建议,如此才能最大限度地激活城市创新潜力,更好地提升河南省城市整体技术创新能力。

[Purposes]This paper constructs a technical innovation capability evaluation index system for cities in Henan Province to provide corresponding recommendations to assist Henan Province in enhanc-ing its overall technical innovation capabilities.[Methods]By using factor analysis and cluster analysis methods,selecting 14 indicators including R&D personnel and financial expenditure for technology.From the perspectives of technology innovation input capability,technology innovation efficiency capabil-ity and technology innovation potential capability,this paper constructs an evaluation index system for the technological innovation capability of 18 cities in Henan Province,and evaluates the technological in-novation capabilities of the 18 cities in Henan Province.[Findings]By setting the factors of input innova-tion performance and innovation potential,using the ratio of the variance contribution rate and cumula-tive contribution rate of each factor as weights,a comprehensive score is obtained,which is used to rank the technological innovation capabilities of each city.Subsequently,through systematic clustering,the 18 cities in Henan Province are classified into five categories.[Conclusions]In conclusion,it is recom-mended that cities in Henan Province should increase policy support and encourage innovation and en-trepreneurship.There should be a focus on strengthening talent attraction and investment in technologi-cal innovation.Additionally,cities should enhance cooperation and promote industrial development among them.These approaches will help maximize the innovation potential of cities and better elevate the overall technological innovation capability of Henan Province.
