本文采用DEA模型和超效率DEA模型对2013年中国31个省份工业企业的自主创新效率进行测度,在此基础上利用DEA两阶段法对工业企业自主创新效率的影响因素及其影响方向进行实证分析。研究结果显示,创新产出较高的省份自主创新效率总体水平较高,规模无效率是造成技术无效率的主要原因。政府资金支持和技术市场活跃度对工业企业自主创新效率有负面影响,地区经济对外开放程度和高技术产业发展水平对工业企业自主创新效率有正面影响。
In this paper, the DEA model and the super-efficiency DEA model were used to measure the independent innovation efficiency of industrial enterprises in 31 provinces in 2013. Based on this, the author uses the two-stage DEA method to analyze the influencing factors and influencing directions of industrial enterprises’ independent innovation efficiency . The results show that the overall innovation efficiency of provinces with higher innovation output is higher, and the inefficiency of scale is the main reason that causes the inefficiency of technology. Government financial support and market activity have a negative impact on the efficiency of independent innovation in industrial enterprises. Regional economic opening up and the development of high-tech industries have a positive impact on the efficiency of industrial enterprises’ independent innovation.
