The existing quality of accounting information detection methods have large errors and cannot meet the needs of listed companies. Therefore, this paper presents a study on the accounting information quality detection methods of listed companies based on the mobile social network interaction model. The interactive model to obtain accounting information of listed companies based on mobile social network, select accounting information quality detection index, construct the accounting information quality detection index system; Determine the weight of accounting information quality detection index by hierarchical analysis method; construct a panel model based on detection index weight to realize the quality detection of accounting information of listed companies. The experimental results show that the accounting information quality detection error of this method is 0.10%–0.31%. It reduces detection error, improves detection accuracy, has good application performance, and is suitable for the promotion and application of accounting information quality detection.

The traditional financial informatics administration system risk assessment method in the evaluation of system risk can deal with less data throughput, and the system risk assessment effect is not good, so the study of the financial informatics administration system of the risk assessment method under the background of big data is a necessity. The method sets logical nodes according to system modules and builds risk estimation models by finding logical relationships between data. Based on the big data background, according to the utility theory and the risk preference function estimation, choose the big data batch calculation and streaming calculation methods to calculate the system programme risk index and financial data faithless risk index. According to the risk residual value, the probability of a system function failure in the main module and submodule of the system is adjusted, and the risk level is defined by the exponential function to realize the system risk estimation under the background of big data. Experimental results show that compared with the two traditional system risk estimation methods, the proposed method has a larger data throughput and a wider range of risk indicators. It can be seen that the proposed method meets the risk estimation requirements of the enterprise financial informatics administration system.

The economic strength of a country is the external manifestation of its comprehensive national strength. In order to increase a country’s international influence, it must strengthen its own economic development. China’s economy is in a period of rapid development. At this stage, enterprise development is an important factor in promoting steady economic growth. However, economic management plays an important role in the development of an enterprise. Therefore, how to use effective economic management methods to promote the development of enterprises is very important. This method helps to enhance the competitiveness of enterprises and improve the economic efficiency of enterprises. This approach needs to get people’s attention. For productive enterprises, the biggest problem is that the economic benefits are not up to expectations. In addition, spending costs are always well over budget. In fact, this has a lot to do with business management. Before the market, economic system was reformed. The comprehensive management of productive enterprises is mostly extensive management. This makes the economic costs of certain links and details out of control. Therefore, effective management of the economy of a productive enterprise is critical. Although productive enterprises cannot be said to be highly profitable, their economic benefits are at least achievable. For productive enterprises, the most effective management method for the economy is refined management. This article starts from the perspective of improving the speed of enterprise development. Specifically, the starting point is to promote the improvement of the country’s comprehensive national strength. The article analyzes the inherent relationship between economic management and enterprise development, hoping it can provide positive help for China’s social and economic progress.
