Since 2022, new changes and new features have emerged in the issuance and investment of national special bonds. From January to February, the progress of issuing special bonds was accelerated, and the scale of actually available funds increased significantly. The focus of special debt investment is inclined to the field of infrastructure. The traditional infrastructure investment structure is constantly optimized. New infrastructure such as "counting from the east to the west" has become an important field of special debt investment. Investment in people's livelihood continues to expand, with public health and affordable housing as the main growth points. The proportion of special bonds issued in the eastern region has increased significantly, and the investment fields in different regions are differentiated. In the future, we should continue to do a good job in the reserve and progress management of high-quality special debt projects, optimize the investment structure of special debt funds, improve the management system of special debt used as capital, broaden the repayment sources of special debt, and improve the solvency of local governments.
