摘　　要：2008年SNA修订了R&D;支出的核算方法,R&D;支出不再视为中间消耗,而是作为固定资本形成处理。本文依据2008年SNA和我国R&D;统计调查数据等,科学测算了1952年以来每年R&D;活动所形成的资产价值,同时对R&D;资产进口和出口进行了适当调整。然后,在合理选取和估计R&D;资产折旧率、R&D;价格指数和基年R&D;资本存量的基础上,根据永续盘存法对我国1952-2014年R&D;资本存量进行了测算。结果显示,我国R&D;投资与R&D;内部经费支出的年平均比例为95.5%,我国R&D;资本存量总体上呈快速增长趋势,2014年达到42244亿元,且R&D;资本存量与GDP之比呈'N'形趋势,经历了先上升后下降再上升的过程。The treatment of R&D expenditures is revised in SNA 2008,and R&D expenditures is no longer recognized as intermediate consumption,but as fixed capital formation.According to SNA 2008 and R&D survey data in China,this paper estimates accurately R&D investment flows each year since 1952,and considers the imports and exports of R&D assets.At the same time,this paper measures R&D capital stock during 1952~2014with perpetual inventory method,based on reasonable selected R&D assets depreciation rate,R&D price indices and R&D initial capital stock.The results show that,the average ratio of new R&D asset value to R&D expenditure is95.5%;R&D capital stock increases rapidly as a whole,reached 4224.4billion RMB in 2014;the ratio of R&D capital stock to GDP appeared to be 'N'type,with a trend of increasing firstly,decreasing secondly,and then increasing again.
