摘要
在经济学的实证分析中,R&D资本存量是一个重要的指标,特别是对研发效率、创新的产出弹性、TFP等问题的研究中都需要R&D资本存量的数据。本文运用知识生产函数测算出三组不同行业的R&D折旧率,然后运用永续盘存法测算了我国28个制造业在1998-2005年的R&D资本存量,为相关的实证研究提供了基础性数据。
R＆D capital stock plays an important role in the empirical research. Many studies, such as R＆D efficiency, output elasticity of innovation, TFP and so on, need the data of R＆D capital stock. This paper firstly estimates the depreciation rates of different industries on base of the knowledge production function, then measures R＆D capital stock through perpetual inventory method with the data of 28 manufacturing industries in 1998 - 2005. The result provides basic data for related empirical researches.
