摘要
本文在考虑序列几何相似度和相对变化率的基础上,对现有T型关联度进行改进,分别考察绝对关联度和相对关联度,以得到更精确的结果.基于改进T型关联度的计算结果及相关分析表明:海南省的R&D经费投入存在不平衡、不稳定、力度小并且缺乏合理的规划,使得R&D经费投入并没有有效地发挥其对经济发展的推动作用.最后,针对目前海南省科技投入状况,提出了几点建议以供参考.
Considering the geometric similarity and relative change rate of sequences, this paper gives a way to improve the insufficiency on T’s correlation degree and calculate the absolute correlation degree and the relative correlation degree to obtain more accurate results. The calculated results and relevance analysis on Hainan province's R&D expenses by the improved T’s correlation degree show that Hainan province's R&D Planning has some drawbacks, such as funding imbalance and instability, slight and unreasonable planning, which would weaken the economic development by the investments of R&D. Some suggestions are given for reference at the end.
