基于数据包络分析和主成分分析的产业技术创新能力差异化研究

Differentiation research on industrial technology innovation ability by DEA and PCA

为分析中国汽车产业技术创新能力现状及寻找其提升的路径,应用技术创新理论,构建产业技术创新能力分析模型,选取不同产业进行差异化研究。采用基于数据包络分析(DEA)和主成分分析(PCA)的双轨分析方法,从投入端和产出端引入6个影响产业技术创新能力的指标,构建评价指标体系,对我国汽车、家用视听设备和通信设备三个产业技术创新能力进行比对。研究结果表明,我国汽车产业技术创新能力处于中低水平,创新投入能力较弱,投入规模不足,产出能力不平衡;创新转化过程存在失效。

To analyze the technology innovation ability of Chinars auto industry, an analytical model is developed based on the theory of technology innovation. Using this model, the performances of technology innovation ability in auto industry, household audio-visual equipment industry and telecommunication equipment industry are evaluated. The model adopts a new and more sophisticated two-line approach based on Data Envelopment Analysis （DEA） and Principal Component Analysis （PCA）. Furthermore, six factors are introduced into this model. The evaluation results show that the technology innovation ability of Chinars auto industry is in the low level, and it confronts insufficient innovation input and unbalanced innovation output. At the same time, the innovative transformation process faces inefficiency. Finally, several policy suggestions are proposed on improving the technology innovation ability of Chinars auto industry.
