摘要
将加入WTO以来中国航运业的创新驱动发展历程划分为要素驱动、投资驱动和技术驱动3个阶段,采用以数据包络分析(data envelopment analysis,DEA)为主的非参数方法对创新驱动发展的3个阶段进行创新投入和产出效果的效率测度与阶段性比较,分析纯技术效率、规模效率、综合效率和规模报酬。评估结果发现:中国航运业3个发展阶段的创新驱动效果整体处于平稳状态,要素驱动阶段的创新效果最佳,投资驱动阶段的创新效率有所下降,技术驱动阶段的整体效果相对最差。评估结果可为提升中国航运业创新驱动发展效率的政策制定提供理论解释和决策依据。
The innovation-driven development process of China′s shipping industry since Chian′s accession to WTO is divided into three stages:factor-driven,investment-driven and technology-driven.The non-parametric method based on data envelopment analysis(DEA)is used to measure and compare the efficiency of innovation input and output effects in the three stages of innovation-driven development,and analyze pure technical efficiency,scale efficiency,comprehensive efficiency and return to scale.The research finds that,the innovation driving effect on the three evolutionary stages of the shipping industry is in a stable state as a whole,the innovation effect of the factor driving stage is the best,the innovation efficiency of the investment driving stage begin to decline,and the overall effect of the technology driving stage is the worst.Therefore,the efficiency of innovation-driven shows its periodic characteristics,which provides theoretical explanation and decision-making basis to enhance the effect of innovation-driven development measurement of shipping industry in the next stage.
