市场认同上市公司研发支出资本化的价值吗？——基于创业板的经验证据

Does the market recognize the value of capitalization of R&D expenditure of listed companies?——An Empirical evidence based on the GEM

摘要:

基于创业板2010-2014年的研发支出资本化数据,利用改进后的股票价格模型和股票收益率模型,检验了资本化研发支出的价值相关性,并对不同种类资本化研发支出(自主研发无形资产和开发支出)对公司价值影响的差异性进行了深入分析。研究发现：资本化研发支出与股票价格和股票收益率不相关,费用化研发支出与股票价格和股票收益率显著负相关；自主研发无形资产与股票价格不相关但与股票收益率显著正相关,开发支出与股票价格和股票收益率不相关。研究结果表明创业板上市公司资本化的研发支出具有一定的价值相关性,但股票市场投资者对创业板的资本化研发支出反应不充分,并且这种疑虑主要是由于开发支出导致的。

Abstract:

This paper investigates the value relevance of R D expenditures capitalization using a sample of 1472 firm-year observations over 2010-2014 on GEM Listed Companies in China. The empirical findings show that capitalized R D is irrelevant associated with stock prices and stock returns but expensed R D is negatively associated with stock prices and stock returns. At the same time we find that self-developed intangible assets are irrelevant associated with stock prices but are positively related with stock returns, on the contrary, development expenditures are irrelevant associated with stock prices and stock returns. These results imply that capitalized R D of companies listed on GEM has certain value relevance, but development expenditures decreased the value relevance of R D expenditures capitalization.
