将企业研发模式分为自主研发和合作研发，探讨研发模式和知识距离对企业绿色创新的影响，选取2013-2019年制造业上市公司为样本进行实证检验。研究结果表明：自主研发和合作研发显著正向影响企业绿色创新，合作研发对企业绿色创新的促进作用较强，自主研发次之；知识距离与企业绿色创新显著负相关，知识距离越大，越不利于企业绿色创新；企业间知识距离较近条件下，合作研发对驱动企业绿色创新的效果优于自主研发；企业间知识距离较远条件下，自主研发更有利于企业绿色创新。

The corporate R&D model is divided into independent R&D and cooperative R&D, and the impact of R&D model and knowledge distance on corporate green innovation is explored. Listed manufacturing companies from 2013 to 2019 are selected as samples for empirical testing. The research results show that: independent R&D and cooperative R&D have a significant positive impact on corporate green innovation, cooperative R&D has a stronger role in promoting corporate green innovation, and independent R&D is second; knowledge distance is significantly negatively correlated with corporate green innovation, and the greater the knowledge distance, the greater It is not conducive to the green innovation of enterprises; under the condition of close knowledge distance between enterprises, cooperative research and development is better than independent research and development in driving enterprises' green innovation; under the condition of long knowledge distance between enterprises, independent research and development is more conducive to enterprise green innovation.
