Abstract: Nowadays, digital technology has gradually dominated the technological development. To catch up with this fast-growing dynamic digitalization trend, most enterprises have initialized their digital transformation, which has attracted wide attention of the society. In the process of digitalization, to seek the most adaptive solution to advance the transformation, it becomes vital for each enterprise to identify the current digitalization level of its own. Based on the analysis of the connotation and essence of digitalization and enterprise digital transformation, this paper explores the concept of enterprise digital maturity in combination with the actual needs. Then research team identifies key process areas and specific evaluation metrics through literature research and panelist review. Further, a digital maturity model (DMM) is developed. This model includes five key process areas (strategy and organization, infrastructure, business process and management digitalization, integrated integration, digital performance), 19 primary indicators and 63 secondary indicators. Compared with the current domestic and international evaluation models, this DMM can better present the changes of enterprise operational pattern and the comprehensive fusion and system application of digital technology under the digital commercial ecology. Not only can it provide researchers with insights on digital emerging phenomena, but provide methods and tools for enterprises to assess their digital integration, helping them to establish strategic goals and implementing programs for digital transformation.

Key words: enterprise digitalization, digital transformation, capability maturity model (CMM), digital maturity model (DMM)
