中文摘要：
基于资源观，运用233家上市公司2007--2011年面板数据，研究三类组织冗余对企业研发投资强度的非线性作用．通过F检验表明该回归模型为个体固定效应回归模型，在此基础上，实证研究得出可恢复冗余、可利用冗余与企业研发投资强度之间呈倒U形的非线性关系，潜在冗余与企业研发投资强度为负向线性关系．本研究运用组织冗余理论，拓展了研发投资的理论研究，对于中国企业技术创新投资有实践指导价值．
英文摘要：
Based on the theory of resource, it studied how different slacks influence R＆D investment with the panel da- ta of 233 listed companies from 2007 to 2011. After cross-section fixed effects tests, it finds that the recoverable slack and available slack have inverted U-shaped relationships with R＆D investment and potential slack has negative effect on R＆D investment. It extends the theoretical research of R＆D investment based on the slack theory, and provides the practical value to Chinese firms＇ tech-innovation.
