In the era of digital economy, as the backbone of the development of the real economy, manufacturing enterprises are constantly affected by the market environment and institutional environment, and digitalization has become an important path indispensable for manufacturing enterprises to meet challenges and gain competitive advantages. Effectively identifying and measuring the dimensions of digital capabilities is of great significance for promoting enterprises to achieve digital transformation and development. Based on this, to explore the structural dimensions of digital capabilities of manufacturing enterprises and to develop a measurement scale for digital capabilities, firstly, the dimensional model of the organizational digital capabilities is identified with "digital strategy capability", "digital resource support ability", "digital collaboration ability", "digital analysis ability" and ital learning ability" as the main categories using a rooted theory approach. Secondly, on the basis of sorting out relevant literature, the initial scale of organizational digital capabilities measurement is compiled, and through content validity and structural validity analysis, the first-order five-factor optimal measurement structure of digital capabilities was determined, thereby developing the measurement scale of the organizational digital capabilities. The research will help to reveal the essential composition of digital capabilities of manufacturing enterprises more deeply and provide a theoretical basis for the empirical research of digital capability.
