Research on Efficiency in Financing of Small and Medium Companies Based on DEA Method

At this stage, SMEs cannot survive and grow without the support of large amounts of capital, and the issue of financing efficiency has always been a bottleneck for different types of SMEs. This paper studies the financial data of relevant enterprises by constructing variable index evaluation systems such as anti-risk ability, internal management, financial system, market competitiveness, short-term debt, long-term debt, paid-in capital to property right ratio, comprehensive efficiency, pure technical efficiency, and scale efficiency and takes manufacturing, service, high-tech, and community-based small-sized and medium-sized enterprises as the research points. The DEA model is used to analyze the financing efficiency of enterprises. The results show that small-sized and medium-sized enterprises in high-tech and manufacturing industries are in the stage of increasing returns to scale. In a homogeneous environment, internal financing environment variables, total assets, asset liability ratio, debt service ratio, current ratio, and other variables have an impact on liquidity efficiency. External financing environment variables, science and technology investment, and economic level have a good and significant impact on enterprise financing.
