摘要
中国对能源工业技术创新的投入逐年增加,然而技术创新的产出增幅较小,提高能源工业技术创新效率成为亟待解决的问题。对此,从能源工业技术创新投入和产出的角度,构建技术创新效率评价指标体系,并采用DEA模型方法对能源工业各子行业2003-2011年的数据进行分析,计算出能源工业各子行业的技术创新效率,由此得到能源工业整体的技术创新效率。根据模型松弛变量的计算,分析能源工业技术创新投入和产出的改进幅度,得出调整建议:一方面加大技术获取和改造费用的投入;另一方面提高技术创新成果的经济转化效益。
The inputs into technology innovation of energy industries in China have been increasing year by year,but less outputs.Therefore,the first problem is to improve the efficiency of technology innovation. From the perspective of inputs and outputs,the evaluation index system of technological innovation effi-ciency of energy industry has been established.And then,DEA method is used to analyze the data of sub-sectors in energy industry from 2003 to 2011 with the results that both technology innovation efficiency of sub-sectors and the overall technology innovation efficiency in energy industry can be realized.Finally, based on the analysis of slack variable,some suggestions are offered for improving the technology innova-tion efficiency in energy industry.
