Abstract: In order to analyze the effect of financial sharing services,we established a financial index system for evaluating the enterprise competitiveness based on the market structure,basic resources and new capabilities theory.Our results demonstrate that:In terms of market position,the implementation of financial sharing services has enhanced the effectiveness of enterprise capital management,improving the quality of operating income.However,the operating income growth rate has shown a negative growth,indicating that financial sharing services have a delayed effect on market expansion capabilities.In terms of capital resources,financial sharing services have improved the enterprise's ability to raise funds and solve its debts.The enhanced ability to control risks allows enterprises to gain a competitive advantage in capital resources.In terms of enterprise capabilities,the financial sharing service  can reduce costs and increase performance,which better serves enterprise strategies and improves their profitability and innovation.In short,the implementation of financial sharing services has been demonstrated to promote the transformation and upgrade enterprise financial management,which helps enterprises to gain opportunities for future development and enhance their competitiveness.
