基于数据包络分析的中国汽车产业创新系统效率研究

The Research on the Efficiency of Chinese Automobile Sectoral System of Innovation based on Data Envelopment Analysis

汽车产业的发展水平和创新能力反映了一国的工业化水平和综合创新能力。产业创新系统理论也适宜分析汽车产业的创新问题。系统效率评价是产业创新系统研究的重要内容,有助于把握产业创新能力的演进过程,为制定相应创新政策提供依据。数据包络分析(DEA)法在创新系统效率评价领域已得到广泛应用。本文提出了一种基于带权重约束的数据包络分析评价方法,对我国汽车产业创新系统的效率进行了评价,对其演进特点进行了分析并提出了相应的政策建议。

The automobile industry is a typical pillar industry for an industrialized country. The theory of sectoral system of innovation is suitable for the innovation problem of the automobile industry. The evaluation of the system efficiency is helpful for realizing evolution of the industrial innovation capacity,comparison between sectors and policy making. As a nonparametric method for input-output efficiency evaluation,data envelopment analysis( DEA) has been widely used on efficiency evaluation of innovation system. This article proposes a method based on the DEA with weight restriction to evaluate the efficiency of the SSI of Chinese automobile industry,discusses the evolution features,and makes some policy suggestions.
