Abstract:Based on the panel data of 30 provinces in China from 2011 to 2018, the DEA-BCC model is used to calculate the development efficiency of China's technology finance, and the fuzzy set qualitative comparative analysis method is used to discuss the science and technology financial policy and the degree of financial development. , The strength of scientific research funding, the strength of government scientific and technological support, the number of scientific researchers and the academic qualifications of scientific researchers and other factors have a joint effect on the development efficiency of China's scientific and technological finance. The research shows that: (1) Efficient science and technology financial development has the characteristics of "multiple concurrency", and multiple factors are needed to achieve efficient development They work together, and science and technology finance policies are an important factor in promoting the development of science and technology finance; (2) There are four ways to promote the development of efficient science and technology finance in the region, which are policy-balanced, comprehensive collaboration, scientific research investment and environmental manpower.
