中文摘要：

现有研究在探讨企业R＆D投入与创新绩效之间的关系时，忽略了技术获取模式在其中的调节作用。本文以企业技术获取模式为调节变量，提出了R＆D投入、技术来源、国外技术引进方式和企业创新绩效的理论模型，并结合浙江高技术企业的问卷调查结果，采用分组回归方法进行实证分析。研究发现：企业R＆D投入与创新绩效显著正相关；以自主研发作为企业主要技术来源，以及以购买技术资料或专利作为引进国外技术的主要方式，对企业R＆D投入与创新绩效的关系起正向调节作用；以合作研发为主要技术来源，以及以购买设备、购买样品、聘请国外技术人员等为引进国外技术主要方式，对企业R＆D投入与创新绩效的关系起反向调节作用。

英文摘要：

When the relationship between enterprise R＆D investment and innovation performance is explored, the existing studies ignore the regulation effect of technology acquisition pattern on the relationship. By taking technology acquisition pattern of enter-prise as a regulation variable, a theoretical model involving the R＆D investment, the source of technology, the introductive pat- tem of foreign technology, and the enterprise innovation performance is presented, an empirical analysis is conducted by using a grouping regression method, combining with the results of a questionnaire survey for the high - tech enterprises in Zhejiang Prov-ince. The findings provided are as follows ： There is a significantly positive correlation between enterprise＇ s R＆D investment and innovation performance. Independent R＆D as the main source of enterprise technology, and the purchases of technical data or pa- tents as primary pattern of foreign technology introduction make a positive regulation effect on the relationship between enterprise＇ s R＆D investment and innovation performance. Whereas cooperative R＆D as the main source of technology, and the purchases of foreign equipments or samples as well as the engagement of foreign technical personals as the primary pattern for bring in foreign technology all have a negative regulation effect on the relationship.
