Abstract In this paper, a dynamic evaluation model of the functional requirements of enterprise finance centers is first established. Then a technology and business evolution monitoring model is constructed based on the Markov chain. According to the model of the technology-business evolution chain, the functional demand dynamic evaluation indexes are summarized, and the indexes are reduced by a rough set algorithm to improve the functional demand dynamic evaluation effect. Establish the functional demand dynamic evaluation method. A new decision tree algorithm is used to confirm the branches of the evaluation so as to decompose the evaluation system, realize the grounding of indicators, and provide auxiliary information for the enterprise’s financial sharing function optimization decision. Since the establishment of the financial shared service center of Enterprise S in 2014, its sustainable growth rate has decreased by 18.89% from 2014 to 2016. However, from the beginning of 2017 to 2019, the rise is as high as 20%. Thus, the establishment of the financial shared service center has improved the sustainable growth of the enterprise.
