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。
In the empirical analysis of economics, the R & D capital stock is an important indicator, and in particular, R & D capital stock data are needed in the research on R & D efficiency, innovative output elasticity and TFP. In this paper, we use the knowledge production function to calculate the R & D depreciation rate of three groups of different industries, and then use the perpetual inventory method to calculate the R & D capital stock of 28 manufacturing industries in China from 1998 to 2005, which provides the basic data for the relevant empirical research.
