Abstract: Greater self-reliance and strength in science and technology is the key to the modernization with Chinese characteristics.Finance and science and technology are closely related,and financial support is indispensable to achieving high-level scientific and technological self-reliance.To this end,key financial support should be given to scientific and technological innovation enterprises,scientific research institutes and colleges and universities,government departments at all levels and central banks being the administrative entities and financial institutions and capital markets being the market entities.Through the two-way role of administrative mechanisms and market mechanisms,full play is given to the financing function,risk management function and information disclosure function to achieve four major goals.Due to the natural opposition between the high risks of greater self-reliance and strength in science and technology and the operating principles of commercial banks,as well as the imperfect development of capital market and high financing threshold,some technology companies have been crowded out of market;the underdevelopment of science and technology insurance has caused insufficient supply and demand in the insurance market;and the shortage in science and technology guarantee system has restricted financial support for greater self-reliance in science and technology.Considering this,we should break through key problems and improve the quality and efficiency of financial support for high-level scientific and technological self-reliance through diversified financial product innovation and institutional innovation.We should improve top-level design,give full play to the promoting role of the government and financial regulatory authorities,and explore new models of financial support for high-level scientific and technological self-reliance.We should establish and improve risk protection mechanisms,and speed up efforts to achieve greater self-reliance and strength in science and technology.
