Research on Digital Maturity Measurement Index System of Small and Medium-Sized Manufacturing Enterprises Digital Innovation

Objectives: Facing the tidal wave of the global digital, taking advantage of the trend to carry out digital transformation is an inevitable choice for the development of small and medium-sized manufacturing enterprises. Based on the analysis of digitalization, digital transformation and digital maturity and other related documents, the paper developed a digital maturity model for small and medium-sized manufacturing enterprises (Digital maturity model, DMM), and designed a rule-based digital maturity level identification method. The literature method and expert review method are used to refine the digital maturity index system of small and medium-sized manufacturing enterprises, and the specific weight of the evaluation index is calculated by the analytic hierarchy process. The model includes 4 first-level indicators, 14 second-level indicators, and 36 third-level indicators for digital infrastructure, core business digitalization level, digital human resource level, and digital transformation management. Using the proposed index system and the corresponding digital maturity level identification method, the digital level of small and medium-sized manufacturing enterprises and their value chains can be evaluated, which helps enterprises to achieve strategic goals of digital transformation in a targeted manner, and provides effective solutions for the development of digital transformation of enterprises. The evaluation methods and tools also provide useful reference and guidance for the theoretical community.
