发达国家科研投入效率初探——基于16个OECD国家纵列数据的统计学分析

Efficiency of Scientific Input in Developed Countries

以16个OECD国家作为研究对象,以SCI来源期刊论文量作为衡量一国科研产出的指标,通过纵列数据(Panel Data)分析方法建立了科研投入-科研产出关系模型,定量描述了发达国家科研产出与科研经费投入、科研人员数、时间等因素的关系。为了排除母语因素对SCI论文量可能产生的影响,语言变量也被引入到模型中。同时,还比较了不同统计模型估计出的不同结果,验证了统计模型选取的重要性。

Based on panel data and regression models, this paper investigates the relationship of scientific input and scientific output of 16 OECD countries. The authors use the account of SCI papers as the indicator of scientific output, scientific expenditure ,and scientific personnel as the indicator of the scientific input. To eliminate the possible effect of native language on SCI papers, The authors also introduce language into the regression models. Furthermore, to show the importance of model selecting, The authors compare the parameters estimated from different models.
