外部创新氛围对服务创新绩效有重要的影响，但对其具体的作用机理现有文献还未进行深入剖析。基于国内外相关文献梳理，探索性地提出以双元学习能力为中介变量的外部创新氛围对服务创新绩效影响的概念模型，并通过对212家知识密集型服务企业的实证研究发现：（1）政策氛围、竞争氛围和合作氛围均能对服务创新绩效产生积极的正向影响；（2）知识获取和知识利用均对服务创新绩效具有积极的正向影响；（3）同时追求知识获取和知识利用反而会对服务创新绩效产生负向影响；（4）知识获取在政策氛围、竞争氛围与服务创新绩效之间起到完全中介作用，而合作氛围对服务创新绩效的影响需要通过知识获取和知识利用的完全中介作用。

External innovation atmosphere has an important impact on service innovation performance, but an in-depth exploration of its specific working mechanism is still lacks. Based on relevant literature review from domestic and overseas, this paper presents an integrated framework for analyzing external innovation atmosphere, ambidextrous learning capacity and service innovation performance. By conducting an empirical study of 212 sample KIBS enterprises, the results indicate that: (1) Policy atmosphere, competitive atmosphere and cooperative atmosphere all have significant positive effects on service innovation performance; (2) Knowledge acquisition and knowledge utilization both have significant positive effects on service innovation performance; (3) The interaction between knowledge acquisition and knowledge utilization negatively affects service innovation performance; (4) Knowledge acquisition plays a complete intermediary role between policy atmosphere, competitive atmosphere and service innovation performance, The effect of cooperative atmosphere on service innovation performance requires the complete mediating effect of knowledge acquisition and knowledge utilization.
