Abstract: Based on the data for SRUI (Specialized, Refined, Unique, and Innovative) Giant SMEs (small and medium-sized enterprises) among Shanghai and Shenzhen A-share listed enterprises from 2013 to 2021, this paper explores the impact of the SRUI strategy and different strategic categories on the quantity and quality of enterprise innovation, and analyzes the moderating role of digital transformation in these relationships. The empirical results show that the SRUI strategy, Specialized strategy and Innovative strategy all positively affect both the quantity and quality of enterprise innovation, whereas the Refined strategy does not contribute to improving innovation quality. Furthermore, the degree of digital transformation plays a positive moderating role in the relationship between the SRUI strategy and both the quantity and quality of innovation. Specifically, digital transformation not only positively moderates the relationship between Specialized strategy and innovation quality but also significantly enhances the impact of the Innovative strategy on promoting both the quantity and quality of enterprise innovation. These findings provide valuable insights for the high-quality development of SMEs and their transformation and upgrading to the “SRUI” strategy.

Key words: SRUI (Specialized, Refined, Unique, and Innovative) strategy, innovation quantity, innovation quality, digital transformation

摘要： 基于2013~2021年中国沪深A股上市的专精特新“小巨人”企业数据，探究专精特新战略及其各维度对企业创新数量和创新质量的作用效果，分析企业数字化转型程度在上述关系中的调节作用。研究结果表明：专精特新战略、专业化战略和新颖化战略对企业创新数量和质量均存在正向影响，精细化战略则不利于企业创新质量的提升；企业数字化转型程度在专精特新战略与企业创新数量及质量关系中起正向调节作用，其不仅正向调节专业化战略与企业创新质量的关系，还显著增强了新颖化战略对企业创新数量及质量的促进作用。研究结论为中小企业进行“专精特新”转型升级和创新高质量发展提供有价值的参考。
