Abstract: Since the pilot of deepening the reform of collective forestry rights mortgage system in 2014, Chengdu has explored and improved the financial support system and continuously innovated the methods of forest right mortgage and pledge loans, and achieved remarkable results. However, there are also prominent problems such as low evaluation value of forestry rights mortgage, short loan cycle, few forestry-related financial services products and low enthusiasm of state-owned financial institutions. Based on the analysis of the above problems and combined with the domestic practice of public welfare forest right pledge loan, this paper analyzes the potential of public welfare forest right pledge loan in Chengdu, and puts forward some suggestion, including improving the standard system, innovating forestry right mortgage guarantee, providing forestry full-cycle credit products, strengthening financial risk prevention and control, and exploring new models of public welfare forest right pledge loan, so as to provide reference for the government and financial institutions to further optimize and innovate forestry right mortgage loan.
