摘要: 在或有债务不确定触发地方政府代偿的现实背景下,本文对地方政府显性债务和或有债务的结构性风险进行了模型刻画,给出了两类债务违约概率的显示解及其估计方法。基于地方政府报告的显性债务和审计署的有关公告等,本文对地方政府的显性债务和或有债务规模进行了结构性分解和估算,多视角估计了不同久期(或平均债务到期时间)下的两类债务的结构性风险状态,同时对比分析了其变动趋势。模型估计表明:地方政府债务风险的主要形态是或有债务的不确定触发,在部分时段内,地方政府的结构性代偿压力明显较大,但债券置换等旨在拉长债务久期的政策设计有助于缓释地方政府债务的信用风险边界,降低地方政府的结构性代偿压力。本文用具体数字揭示了地方政府债务的结构性风险状况及其变动趋势,以及地方政府债务久期之伸缩与其代偿压力之间的定量关系。

Abstract: In the case of local government compensation uncertainly triggered by third-parties, the paper models the structural credit risks of local government debts, and gives the analytic solutions and estimation methods for the default probabilities of explicit debt and implicit debt. Based on the explicit debt data reported by local governments and the relevant audit announcements of the National Audit Office et al., the paper conducts structural decomposition and calculation for the two kinds of debts, empirically estimates their default probabilities and comparatively analyzes their changing trends. The study shows the major risk of local government debts is the uncertain triggering of contingent debt and local governments have structural pressure to fulfill their compensatory obligation at some certain time points or periods. However, the policy design such as Local Governments Bond Replacement Plans which aims at lengthening the debt duration helps to mitigate the credit risk boundary of local government debts and reduce the structural compensatory pressure of local governments. The paper uses specific figures to demonstrate the structural risks of local government debts and their changing trends, as well as the quantitative relationships between debt duration and the compensatory pressure of local governments.
