摘　　要：本文针对既有研究在研发效率评价时均是基于静态分析视角这一现状,尝试构建了一个动态研发效率分析框架,并采用最新发展起来的动态面板数据随机前沿分析模型对动态研发效率及其影响因素进行测评.选取2001—2008年广东省大中型工业企业为实证样本,演示了动态研发效率评价的具体过程,并就动态/静态研发效率的差异进行了比较分析.研究结果表明:基于动态、静态两种不同思路所构建的模型,其参数估计值呈现出一定差异,但参数所蕴含的基本经济涵义保持了很好的一致性;动态研发效率及其时变趋势也表现出一些新特征.The existing studies are all based on static analysis perspective to evaluate R＆D efficiency, so it tries to es- tablish a dynamic R＆D efficiency analysis framework, and applies the latest developed dynamic panel data stochastic frontier analysis model to evaluate the dynamic R＆D efficiency and its influencing factors. Then, it takes the large and medium-sized industrial firms in Guangdong province as example, to demonstrate how to evaluate the dynamic R＆D ef- ficiency, and compare the difference between the dynamic R＆D efficiency and the static R＆D efficiency. The results show that the two different models based on dynamic and static idea are different on their parameter estimates, but the parameters＇ economic implications maintain good consistency, and the value of dynamic R＆D efficiency and its time-va- rying trends also show some new features.
