Research on digital economy monitoring and evaluation system based on data analysis algorithm

In modern market economy, cyclical economic fluctuations seem to have become an objective phenomenon in a country's economic life. Economic development has ups and downs, as well as ups and downs. Since the reform and opening up, China has in fact been faced with repeated expansion and recession. Economic fluctuations will inevitably affect the behavior of economic subjects. Therefore, we must strengthen the monitoring and evaluation of the digital economy. This paper first analyzes the current situation and trend of digital economy monitoring. Secondly, on the basis of summarizing previous experience, a digital economy monitoring and evaluation system based on data analysis algorithm and fuzzy mathematics is proposed. This paper describes the main content of this method, and constructs the relevant system structure diagram. The calculation method of membership degree designed in this paper is applied to China's economic situation, which conforms to China's actual situation and draws relevant conclusions. Finally, some suggestions and countermeasures are put forward.
