摘要
基于创新过程分析框架,本文将创新过程划分为新技术研发阶段和成果转化阶段,应用改进的两阶段网络DEA模型,对五个典型高技术制造产业的区域整体效率、技术研发效率和成果转化效率进行测算。通过东北三省与其他省市的对比,分析东北三省创新效率的变动趋势以及与其他省市之间的差距。通过不同产业间的效率差异的比较,揭示制约东北三省高技术制造产业创新效率提升的主要因素。研究发现,东北三省的两阶段效率变化呈离散化态势,并未向提升方向收敛;东北三省与其他样本省市的创新效率差距逐渐拉大,不同产业的差距幅度不同,市场化程度较高的产业,差距幅度较大。
Based on the innovation process framework,this paper decomposes the innovation process into new technological R&D stage and transformation stage and uses improved two-stage network DEA model to measure the overall efficiency,technological R&D efficiency and transformation efficiency of regions in five typical high-tech manufacturing industries in China. This paper investigates the changing trend and gap of innovation efficiency of three provinces in Northeast China by comparing innovations efficiency of these three provinces with other regions. It also reveals the main factor which restricts the increase of innovation efficiency in the three provinces. The result shows that,the innovation efficiency of the three provinces presents discrete development trend,instead of converging to a higher level.The innovation efficiency gap between the three provinces and other regions widens gradually,and there is bigger innovation efficiency gap between the three provinces and other regions in the industry with higher level of marketization.
