摘要
R&D价格指数是将当年价格R&D经费支出转换为可比价格的重要工具,是开发R&D卫星账户和进行相关实证研究不可缺少的。文章研究了R&D投入价格指数和产出价格指数的构造方法,并给出了我国大中型工业企业的R&D指数,研究结果表明,1998-2011年,投入价格指数上涨了179个百分点,2001-2011年,产出价格指数上涨了190.82个百分点;结果还表明使用常见的替代指数,如GDP平减指数、PPI、CPI以及这些指数合成的指数,会高估实际R&D经费内部支出及其增长率。
R＆D price index, as an important deflator to deduct current R＆D value into real term, is quite necessary for empiri- cal researches. This paper elaborates the theory and empirical work of constructing the R＆D input and output prices indices for Chi- nese industries. According to the empirical result, the R＆D input prices （1998-2011） increased by 179 percentages, while the R＆D output price increased by 190.82 percentages from the year of 2001 to 2011 for the whole industry. Compared to the R＆D price indices we built in this paper, traditional price indices such as PPI, CPI and the GDP deflator as well as the deflators con- structed upon them which are used by many Chinese scholars are likely to overestimate real R＆D expenditures.
