国内外一些优秀的中小企业通过微创新战略实现了可持续成长，但对于微创新战略是如何促进中小企业可持续成长的问题并没有得到深入的回答。对此，本研究结合动态能力理论对全球吸管行业第一品牌、国内中小企业中的“隐形冠军”义乌市双童公司进行纵向案例分析，试图剖析中小企业微创新战略对企业可持续成长的作用机理。研究发现：（1）中小企业的微创新战略遵循“差异化”-“专业化”-“集成型”-“平台型”的路径演进，这一路径成为驱动企业可持续成长的动力源。（2）在微创新战略的引导下，中小企业通过“环境洞察能力-组织柔性能力-变革更新能力”的循环路径构建并持续提升其动态能力，进而实现可持续成长。（3）在不同的微创新战略作用下，中小企业动态能力提升的机理呈现出结构优化、专业技术知识优化、知识协同优化和共生关系优化四种差异性表现，其根本原因在于企业根据自身战略定位有针对性地集中资源优化价值链上的不同关键性活动。本研究不仅扩展了微创新与企业成长的理论研究，更为我国中小企业可持续成长提供理论参考和管理启示。

  Some outstanding small and medium-sized enterprises (SMEs) at home and abroad have achieved sustainable growth through a micro-innovation strategy, but the question of how micro-innovation strategy promotes the sustainable growth of SMEs has not been deeply answered. In this regard, this study combined with the dynamic capability theory, conducted a longitudinal case analysis of Yiwu Shuangtong Company which is the first brand in the global straw industry and the ‘invisible champion’ of domestic SMEs, in an attempt to analyze the mechanism of micro-innovation strategy of SMEs on the sustainable growth of enterprises. The results showed that: (1) The micro-innovation strategy of SMEs follows the evolutionary path of ‘differentiated’-‘specialized’-‘integrated’-‘platform-based’, which has become the driving force for the sustainable growth of enterprises. (2) Guided by the micro-innovation strategy, SMEs build and continuously improve their dynamic capabilities through the circular path of "environmental insight capability-organizational flexibility capability - change and renewal capability", thereby achieving sustainable growth. (3) Under the influence of different micro-innovation strategies, the mechanisms of dynamic capability improvement of SMEs present four different manifestations including structure optimization, specialized technical knowledge optimization, knowledge coordination optimization, and symbiotic relationship optimization, and the fundamental reason is that enterprises according to their own strategic positioning focus resources on optimizing different key activities in the value chain. This research has not only expanded the theoretical framework of micro-innovation and enterprise growth but also provide theoretical reference and management enlightenment for the sustainable growth of SMEs in China.
