[Four departments: Guide and support qualified gas turbine companies to expand financing channels through listing, bond issuance, etc.] On October 30, the National Energy Administration and other four departments issued guidance on promoting the innovative development of gas turbines. It proposes to strengthen fiscal and financial support. Implement preferential tax policies such as super deductions for R&D expenses and accelerated depreciation of fixed assets. Financial institutions are encouraged to provide diversified financial services such as loans, guarantees, financial leases, and commercial insurance to qualified gas turbine development enterprises and independent gas turbine projects. Increase the support of major national science and technology projects for key gas turbine equipment research. Encourage enterprises to apply for policy support such as "double-level", re-loaning, and fiscal interest discounts, expand medium- and long-term loans to the manufacturing industry, and guide and support qualified gas turbine enterprises to expand financing channels through listings and bond issuances.
