Abstract: Micro-innovation of SMEs is faced with the problem of spontaneous blindness and uncertainty of results. The key to the problem is the answer to the implementation paths of micro-innovation. Based on the in-depth interview data of 44 enterprises in 5 cities of Zhejiang Province, using the grounded theory of qualitative research method and with the help of Nvivo 11.0 software auxiliary coding, the implementation strategies of micro-innovation, which are coupled and progressive, such as user interaction, trial-and-error learning, rapid iteration, cross-boundary integration, and single-point breakthrough, are concluded. Then preliminarily construct a new development path model of SMEs.The implementation of micro-innovation relies on three key mechanisms: user interaction mechanism, iterative trial-and-error mechanism and cross-border integration mechanism. Among them, the user interaction mechanism runs through the whole process of micro-innovation, the iterative trial-and-error mechanism makes micro-innovation spiral upward, and the cross-border integration mechanism guarantees the advancement of micro-innovation. By analyzing the development path of Micro-innovation of SMEs and summarizing the key mechanism of their successful realization, the relevant theoretical research has been improved, and it has positive guiding significance for the practice of SMEs.

摘要： 中小企业微创新常面临着行为自发盲目性、结果不确定性等问题，问题解决的关键在于对微创新成功实现的路径做出解答。以浙江省五市共44家企业的深度访谈数据作为基础，运用质化研究方法扎根理论，借助Nvivo11.0软件辅助编码，归纳出用户交互、试错学习、快速迭代、跨界整合、单点突破等相互耦合又层层递进的微创新实施策略，并初步构建中小企业微创新的发展路径模型。微创新的实现依托三大关键机制：用户交互机制、迭代试错机制以及跨界整合机制。其中，用户交互机制贯穿于微创新全过程，迭代试错机制使得微创新实现螺旋式上升，跨界整合机制保障微创新的超前性。分析中小企业微创新的发展路径并总结归纳其成功实现的关键机制，既完善了相关理论研究，同时对中小企业微创新的实践具有积极的指导意义。
