Abstract:Abstract: Value evaluation of data assets is the core link to realize the capitalization of data elements. It is an urgent need to cultivate the data element market and realize the data elementization. This study takes Internet enterprise data assets as the research object, starting from the perspective of systems theory and based on the data value chain theory, systematically sorts out the factors affecting the value of data assets, constructs a data asset value system dynamics model, discusses the complex impact of various influencing factors on the value of data assets by category, and analyzes the hysteresis effect of digital asset value release from three stages. Experimental results show that the value of data assets is affected by its own attributes such as data scale, quality, and timeliness, as well as external characteristics such as technology, organization, and environment. Its value realization is a dynamic process with a law of decline. There is a significant hysteresis effect in the release of digital asset value.Therefore, it is suggested to clarify the different enabling stages of data assets from the whole life cycle of data generation to play a role. Considering the influence of many factors including technical organization and environmental factors; Innovative assessment methods to complement each other.
