摘　　要：依据雅各布外部性理论探究相关多样性对企业创新的影响,基于2007—2013年上市公司数据,运用PSTR模型实证检验相关多样性对企业创新的非线性影响。研究发现:相关多样性对企业创新有正向作用;随着研发投入的不断增加,相关多样性对企业创新产生非线性影响;企业所有制性质不同,相关多样性对企业创新的非线性影响也不相同;随着研发投入的不断增加且突破某一临界值,在更高的研发投入诱导下,中、西部地区相关多样性对辖区企业创新产生更为强烈的正向作用。According to Jacob externality theory,this study explores the impact of related variety on enterprise innovation,based on the data of quoted company from 2007 to 2013,this study utilizes PSTR model to test the nonlinear influence of related variety on enterprise innovation. The results show that: the related variety has a positive effect on the enterprises innovation; in the pace with the increasing of R&D investment,the related variety has a nonlinear impact on enterprise innovation.Different enterprise ownership has a different nonlinear influence of related diversity on related variety. In the pace with the increasing of R&D investment,the higher R&D investment leads to a stronger positive effect of related variety on related variety in middle and west areas.
