摘 要
本文立足于创建低碳节约型社会的大背景，选取2004-2013年我国沪深两市新能源行业14家上市公司的数据，设立相关变量，确立了研究模型，运用excel和stata软件实证分析了R&D投入与企业业绩之间存在的关系。实证结果表明在我国新能源行业中：企业的研发强度还较低，仍然有很大的提升空间。通过对企业研发强度分别与企业净资产收益率、每股收益、主营业务收入增长率的实证分析，从企业盈利能力和企业发展能力两个方面来实证研究新能源企业R&D投入同企业业绩之间的相关关系，发现企业研发投入与企业业绩确实存在一定的相关关系，研发经费投入强度（RDES）和研发人力资本投入强度（RDPS）与企业当期业绩之间既存在正向相关关系，也存在负向相关关系，与此同时实证结果也表明企业研发投入对企业业绩的影响具有滞后性。

ABSTRACT
This paper based on the establishment of a social background carbon-saving society, select the data of new energy industry of China's Shanghai and Shenzhen listed companies from 2004 to 2013 , the establishment of relevant variables, established a research model, using excel and stata make a empirical analysis between R&D and investment corporate performance . The empirical results show that China's new energy industry: R&D strength of enterprises is still relatively low, there is still much room for improvement. By the same corporate R&D intensity of ROE, EPS, main business revenue growth regression analysis, from corporate profitability and business development capabilities to both empirical new energy enterprises R&D (research and development investment) with the enterprise correlation between the performance characteristics found R&D investment and corporate performance does exist a certain correlation between the intensity of R&D expenditure (RDES) and R & D investment in human capital both positive correlation between the intensity (RDPS) and corporate performance, but also negative correlation, while the empirical results also show that the impact of R&D investment in corporate performance with a lag.

Key words: R&D enterprise performance empirical research
