财政监管会对金融市场产生何种影响是财政政策与金融政策协调的重要内容。文章利用始于 2015 年各地发布的"融资平台转型"专项文件作为财政监管政策的典型冲击和事件窗口,借助 2010-2021 年全国 3 269 家地方融资平台及其所在地级市综合面板数据,系统使用了因果推断的多种方法,试图探究针对债券发行主体的财政强监管如何作用于债券一级市场。研究发现,该类文件传递了明确的"不兜底""强监管""促转型"信号,会对不同风险状况的地方融资平台潜在信用风险产生不同影响,并表现为债券发行"溢价"(或"折价")效应:财政监管政策传递的"不兜底""强监管""促转型"信号在短期显著提升了地方融资平台在债券一级市场的加权平均发行利差;在债务率水平较高且发生过债券违约情况的地区,地方融资平台加权平均发行利差在政策信号影响下显著上升;而在债务率水平较低且未发生过债券违约的地区,则其定价表现相反。这一发现验证了财政监管有助于加强债券一级市场对地方融资潜在信用风险的差异化精确识别,提供了财政监管对于金融市场定价效率提升的佐证。
How does Fiscal Regulation Affect Bond Market Pricing?Evidence from a Quasi-natural Experiment Based on Financing Platform Transformation Policies
The Report to the 20th National Congress of the Communist Party of China pointed out the need to establish a modern fiscal and financial system,ensure financial stability,and regulate and guide the healthy development of capital in accordance with the law.Thus,exploring the policy efficacy of fiscal regula-tion in financial markets is crucial for further refining the regulatory system of state-owned financial capital and achieving synergy in fiscal and financial policies.This paper takes the"Financing Platform Transformation"policy documents issued across various re-gions since 2015 as a typical policy shock and event window to explore how stringent fiscal regulation tar-geted at bond issuers affects the primary bond market.Employing comprehensive panel data from 3269 local financing platforms and their respective prefecture-level cities from 2010 to 2021,the study systematically ap-plies multiple causal inference methods,and finds that these documents convey clear signals of"no bailouts""stringent regulation"and"promoting transformation",which have different impacts on the potential credit risk of local financing platforms with different risk conditions,and manifest as a"premium"(or"discount")effect on bond issuance.Specifically,the policy signals significantly increase the weighted average issuance spread in the short term for local financing platforms in the primary bond market;in regions with a higher debt level and prior bond defaults,the weighted average issuance spread significantly increase under the impact of the policy signals;in regions with a lower debt level and no prior bond defaults,the pricing exhibits the oppos-ite trend.The marginal contributions of this paper are as follows:First,it considers the potential credit risk of local financing platforms as the main mechanism,proposes an analytical framework on how fiscal regulation af-fects bond pricing,and validates the effectiveness of the analysis through empirical methods,supplementing existing research on the impact mechanism of fiscal regulation on bond pricing.Second,it takes policy docu-ments on financing platform transformation issued by various regions as the main research object,enriching the content of fiscal regulation policy evaluation.Third,it weights the bond data by issuing entity to create panel data for financing platforms and explores how fiscal regulation affects bond pricing at the local finan-cing platform level,enriching the research on the micro-operational mechanism of local financing platforms.
