Abstract:Based on the SBM model ,this paper mearsures the efficiency of sci-tech finance in 30 districts in China from 2015 to 2018, and the Tobit model was established to analyze the influencing factors. The results show that the efficiency of sci-tech finance in most regions decreases after the elimination of environmental factors, and the gap between regions is large. The proportion of sci-tech allocation in fiscal expenditure, the index of digitization degree, the profit of high-tech enterprises and the number of new product development projects in high-tech industries have significant positive effects on the efficiency of sci-tech finance. The non-performing loan ratio of local financial institutions has a significant negative effect on the efficiency of sci-tech finance. According to the conclusion, this paper puts forward policy recommendations such as strengthening the government's support for sci-tech finance, rationally allocating sci-tech financial sources and introducing innovative talents in digital economy, optimizing the way of risk avoidance, and promoting the high-quality development of high-tech industry.
