Estimation of RD capital stock in China's high-tech industry

摘要

R&D capital stock is often used in the study of high-tech industry, but there are some deficiencies in the existing methods of measuring R&D capital stock. Based on the existing literature, a new method to estimate R&D capital stock is proposed in this paper. We measure the R&D capital stock of 17 industry segments in China's high-tech industry from 2009 to 2015 by this new method and compare the results with the ones calculated by previous methods. It turned out that different measurement ideas and parameter settings have a great influence on the measurement results.
