服务创新已经成为制造企业获取竞争优势的一种有效战略，但现有文献对动态竞争环境下制造企业服务创新战略对竞争优势的影响机理还缺乏深入探讨。鉴于此，本文基于动态能力理论视角，选取247家中国制造企业为样本，对动态环境下制造企业渐进式和突破式服务创新战略对竞争优势的影响关系进行实证研究。研究结果表明：两类服务创新战略对竞争优势的市场绩效和财务绩效这两个维度均具有直接正向影响；市场动态性越高，相比突破式服务创新战略而言，制造企业渐进式服务创新战略更有助于竞争优势（企业相对市场绩效和财务绩效）提升。竞争强度越大，相比渐进式服务创新战略而言，制造企业突破式服务创新战略越有助于竞争优势（企业相对市场绩效和财务绩效）提升。本研究结论对于现存文献有着重要的理论贡献，对于动态环境中的中国制造企业服务化有着直接和引申的管理启示。

Although previous researches have indicated that service innovation is an effective strategy to gain competitive advantages for manufacturing firms, there still lacks an in-depth and clear account of how service innovation strategies actually influence manufacturing firms’ competitive advantages in the context of dynamic competitive environment. Thus，from the perspective of dynamic capability theory, we selected 247 Chinese manufacturing firms as a sample and investigate the practical relationship between service innovation strategies and firms’ competitive advantages. This empirical research indicates that both incremental and radical service innovation strategies have a directly positive impact on manufacturing firms’ competitive advantages in the dimensions of market performance and financial performance. These two strategies contribute more to improving the manufacturing firms’ market performance and financial performance when the market is more dynamic. The competition intensity, as a moderator, has a positive moderating influence on the relationship of the radical service innovation strategy with financial performance, as well as the market performance; while as for incremental service innovation strategy, it only has a positive influence on the relationship of the radical service innovation strategy with financial performance. These findings have important theoretical contributions to the existing literature and also have important practical implications for Chinese manufacturing firms’ service strategy in dynamic environment.
