| 中文摘要: |
| 文章提出有效技术创新的概念,分析了其内在机理,并采用扩展后的三阶段链式网络DEA模型测算了中国高技术产业有效技术创新的总效率和分效率。应用莫兰指数、三维散点图等工具刻画了创新效率的空间溢出效应和时空演化特征。研究发现:大部分省份的总效率均有不同程度的提高,但区域之间及区域内部各省份间的创新发展仍欠协调,尚未发现其存在显著的空间溢出效应；分阶段效率值大致呈现出第二阶段偏高、第一阶段居中、第三阶段较低的分布特征,这说明创新成果实现阶段仍是影响有效技术创新效率提升的薄弱环节,应重点采取措施加以突破。 |
| English Summary: |
| This paper puts forward the concept of effective technological innovation(ETI), analyzes its internal mechanism, and uses the expanded three-stage chain network DEA model to measure the ETI's total efficiency and sub-efficiency of China's high-tech industry. Then, Moran index and three-dimensional scatter diagram are used to describe the spatial spillover effect and spatio-temporal evolution characteristics of ETI. The study found that the total efficiency of most provinces has been improved in varying degrees, but the innovation and development between regions and provinces within the region is still not coordinated, and it hasn't been found there is a significant spatial spillover effect. The distribution characteristics of three-stage efficiency value roughly shows the second stage is higher, the first stage is in the middle and the third stage is lower, which shows that the realization stage of innovation achievements is still a weak link affecting the improvement of ETI' efficiency, and measures should be taken to break through. |
