| In December 2022,the Central Committee of the Communist Party of China and the State Council issued the Opinions on Building a Data Infrastructure System to Better Play the Role of Data Elements,which supports the exploration of diverse pricing models and price formation mechanisms that are consistent with the characteristics of data elements.At present,there is a huge demand for data trading in China.However,the lack of scientific and reasonable pricing basis for both sides of the transaction has led to difficulties in data circulation.How to accurately assess the value of data assets is an issue worthy of in-depth study and exploration at this stage.Based on the existing research,this thesis selects data assets of Internet enterprises as the research object,elaborates the concept of data assets,and conducts an in-depth discussion on the basic matters of valuation.Secondly,the data asset valuation method is analyzed and the cost method is considered to be applicable at this stage.Based on the cost method model proposed in the Asset Appraisal Expert Guideline No.9 document,the data asset replacement cost,data asset quality adjustment coefficient,potential social value and potential economic value,and data asset value separation are improved.Finally,the improved cost method model was applied to evaluate the cyber security data assets of the case company,Qihoo 360 Technology Co.Ltd.to test the application effect.The results of the study show that(1)the data asset replacement cost should be analyzed in conjunction with the data asset value chain when calculating the data asset replacement cost.(2)Based on Tan’s practical experience in data governance and data quality management,it is proposed that establishing quality rules based on data characteristics,using the proportion of the quantity of data satisfying the rules to the total data volume as the scoring basis,and then combining with the hierarchical analysis method to assign rule weights,can obtain more objective data quality adjustment coefficients.(3)The introduced potential economic value factor and potential social value factor reflect the economic value as well as social value brought by the use of data assets.(4)The improved cost method model is used to calculate the total value of data assets,and then deduct the value of other intangible assets to obtain a more accurate data asset value.It is hoped that the research in this paper can provide help for data asset pricing to promote the development of China’s digital economy. |
