【摘要】 本文分别取窗宽为1-5,应用视窗分析模型对我国各省市高校在2003-2007年的科研效率进行动态分析。通过比较不同窗宽的分析结果,发现随着窗宽的增加,我国各省市高校的TE和PE呈递减变化,SE呈无规律变化;科研效率在不同年份对窗宽的敏感程度不同;选择不同的窗宽会使得研究者对科研效率的长期变化趋势得出大相径庭的结论。对于"如何确定理想的窗宽",从理论上提出新的分析方法,研究确定理想的窗宽,建立适合于我国高校科研效率动态分析的更合理的视窗分析模型。与传统DEA模型的分析结果进行对比,发现两者之间存在很大的偏差。这进一步说明了建立理想窗宽的视窗分析模型,对我国高校科研效率进行动态分析是很有必要的,此视窗模型的分析结果更符合科研工作的实际情况。更多还原

【Abstract】 By selecting window width from one to five,window analysis model is used to carry out a dynamic study on scientific research efficiencies at the universities in different provinces of China during the period of 2003-2007.By comparing the results of different window widths,Technical Efficiency(TE),and pure technical efficiency(PE) at the universities in different provinces of China are decrease and Scale Efficiency(SE) is irregularly varied with the increase of window widths.Scientific research efficiencies have different sensibility to the window width in different years.With the different selection of window widths,scholars would obtain radical different conclusions on the long term changing trend of TE,PE,and SE.For the problem how to determine the optimal window width,a new analysis method is thieoritacally proposed,the study determines the optimal window width,a more researnoable window analysis model that is suitable to the dynamic analysis on scientific research efficiencies at the universities of China is built.The dynamic results are compared with the results based on conventional DEA models,and great variances between two of them are found,it is further proved that setting up a window analysis model with an optimal window width to conduct a dynamic study is necessary and the results further accord with the reality of scientific research activities.更多还原
