At present, due to the rapid development of information technology, problems such as low financial work efficiency, high operating costs, imperfect internal control system and inadequate risk control have emerged. In order to improve and solve these problems, many companies have put forward a financial sharing solution, which in essence is to centralize financial data and carry out standard assembly-line reform on part of financial work. However, this only improves the efficiency of financial accounting to a certain extent, but does not improve the financial value creation ability, and cannot meet the deep-level requirements of enterprises. Therefore, with the gradual development of management accounting theory, the integration of industry and finance will gradually become the trend of financial management in the future. In this paper, financial sharing is the starting point to study financial integration. Yonghui Supermarket is selected as the research object. Firstly, the general situation of the company and the establishment process of its financial sharing center are introduced. Secondly, it analyzes the effect of financial integration under the corporate financial sharing model. Finally, the research conclusions of this paper are put forward.
