摘　　要：根据公共产品理论、创新理论建立了政府研发投入、企业研发投入、知识产权保护强度之间的影响因素模型。利用1992-2012年的数据进行了回归分析,发现政府给企业的科技投入、政府给科研院所的科技投入和政府给高校的科技投入对企业研发投入有杠杆作用,但政府给高校的科技投入的杠杆作用不够突出。另一个重要发现是良好的知识产权保护也能促进中国企业研发投入。进一步进行Granger因果关系检验,发现在2002年前后知识产权保护对中国企业研发投入产生了结构性变化,知识产权保护对企业研发投入的杠杆作用上升为0.147,较之前的影响效应提升了一倍,超过了政府给科研院所的科技投入和政府给高校的科技投入的杠杆作用,证实了知识产权保护是促进中国企业技术创新的动力源泉。This paper establish impact factor model among government R＆D investment,enterprises R＆D investment and IPRP strength on the basis of public goods theory and innovation theory. This paper uses the data of 1992- 2012 for regression analysis,discovers that governmental R＆D investment in enterprises,in institutions,in universities has a leverage effect on enterprises’ R＆D investment,though the leverage effect caused by governmental R＆D investment in universities is not prominent,that proper intellectual property rights protection can promote Chinese enterprises’ R＆D investment. The further Granger causality test shows that intellectual property rights protection produced structural changes in Chinese enterprises’ R＆D investment around 2002,its leverage effect goes up to 0. 147,which is double of previous effect,exceeding the leverage effect caused by governmental R＆D in institutions and in universities; it verifies intellectual property rights protection is the source of power for promoting Chinese enterprises technology innovation.
