专辑 | 地方政府债务置换对城投债发行定价的影响——基于特殊再融资债视角

Core Viewpoint - The issuance of special refinancing bonds significantly reduces the credit spread of urban investment bonds, primarily through enhancing the implicit guarantee capacity of local governments [1][25]. Group 1: Research Background - The increasing economic downward pressure and adjustments in the real estate market have weakened the debt repayment capacity of some local governments, leading to rising issuance rates and credit spreads for urban investment bonds since 2023 [2]. - The Chinese government has emphasized the importance of preventing systemic financial risks and has adopted special refinancing bonds as a tool for debt restructuring and risk mitigation [2][3]. Group 2: Literature Review - Existing studies have focused on the impact of replacement bonds since 2015, highlighting their role in reducing interest expenses and extending debt maturity, which significantly affects urban investment bond rates and credit spreads [3]. - Special refinancing bonds, introduced in late 2020 and expanded in 2023, aim to address hidden debts not included in budgets, yet they have received limited academic attention [3]. Group 3: Empirical Analysis - The study analyzes data from 2021 to 2024, utilizing a sample of 13,413 urban investment bonds, with data sourced from authoritative databases and official statistics [8][9]. - The main variable, the credit spread of urban investment bonds, reflects the premium over risk-free rates and is crucial for measuring financing costs [9][10]. Group 4: Hypotheses and Mechanisms - Hypothesis one posits that the issuance of special refinancing bonds significantly lowers the credit spread of new urban investment bonds [5]. - Hypothesis two suggests that special refinancing bonds enhance local governments' implicit guarantee capacity, thereby reducing the credit spread of new urban investment bonds [7][20]. Group 5: Results and Robustness Checks - The results indicate that an increase in the special refinancing bond ratio significantly lowers the credit spread across various model specifications, confirming hypothesis one [15][16]. - Robustness checks further validate the findings, showing that the impact of special refinancing bonds on reducing issuance spreads remains significant under different variable constructions and sample sizes [17][18]. Group 6: Mechanism Analysis - The analysis reveals that the issuance of special refinancing bonds significantly enhances the market's perception of local governments' implicit guarantee capacity, which in turn reduces the credit spread of urban investment bonds [21][23]. Group 7: Conclusions and Policy Recommendations - The study concludes that special refinancing bonds effectively lower the financing costs of urban investment bonds by enhancing local governments' implicit guarantee capacity [25]. - Recommendations include establishing a supportive mechanism for special refinancing bonds linked to the operational efficiency of platform companies and reforming credit pricing mechanisms to mitigate implicit guarantee expectations [27][28].
