【摘要】：2008年金融危机后,我国政府在科技活动方面的投入大量增加,如何评价其产出效率并发现约束科技活动效率提高的瓶颈因素,为政府宏观调控提供决策依据,是一个值得研究的问题。运用Malmquist-DEA指数法对2009-2012年内地30个省市的面板数据进行动态评价,在此基础上利用影子价格法对约束创新效率提升的瓶颈因素进行分析。研究发现:1FDI在我国存在知识溢出正效应,当增加FDI投入指标时,创新效率值得到帕累托改善;2我国科技创新效率存在明显梯度特征,东部地区和西部地区效率高,中部地区效率低;3金融危机后,24个省市的科技创新效率提高,主要是通过外部技术进步实现的,而内部资源配置与科技管理水平基本不变;4制约企业科技创新效率提高的瓶颈要素是RD投入,科研机构与高校的RD投入对于企业科技创新具有正向溢出效应。
[Abstract]:After the financial crisis in 2008, our government's investment in scientific and technological activities has increased greatly. How to evaluate its output efficiency and find out the bottleneck factors that constrain the improvement of the efficiency of scientific and technological activities, so as to provide the decision basis for the government's macroeconomic regulation and control. Using Malmquist-DEA index method to dynamically evaluate the panel data of 30 provinces and cities in the mainland from 2009 to 2012. On this basis, the shadow pricing method is used to analyze the bottleneck factors that constrain the improvement of innovation efficiency. It is found that there is a positive effect of knowledge spillover in China, and when increasing the input index of FDI, it is found that there is a positive effect of knowledge spillover in China. The efficiency of science and technology innovation in China has obvious gradient characteristics. The efficiency of science and technology innovation in the eastern and western regions is high. After the financial crisis in the central region, the efficiency of scientific and technological innovation in 24 provinces and cities has been improved. It is mainly achieved through external technological progress, while the internal resource allocation and the level of science and technology management are basically unchanged. 4. The bottleneck factor that restricts the efficiency improvement of enterprise's scientific and technological innovation is R D input. The R D investment of scientific research institutions and universities has a positive spillover effect on enterprise science and technology innovation.
