党的二十大报告强调守住不发生系统性风险底线.为有效监测我国资本市场与实体部门的金融风险溢出,本文通过TVP-VAR模型测度了金融风险动态溢出指数和吸收指数,利用有向网络拓扑结构考察金融风险主要溢出路径和特殊时期演变规律,再基于TVP-FAVAR模型实证研究宏观政策的金融风险溢出调控效果.研究表明,(1)金融风险溢出效应在2015年后增强,各资本市场与实体部门的风险溢出效应呈非线性.(2)在金融系统内,"股票市场→房地产市场"和"政府部门→企业部门"是主要的风险溢出路径,且次贷危机时期风险溢出效应显著增强,尤其是股票市场,新冠病毒感染疫情时期的风险溢出路径更为复杂.(3)从宏观政策调控效果看,次贷危机期间,提高货币市场利率、降低货币增速和提高法定存款准备金率对风险溢出的调控效果更显著,而疫情期间,财政政策和外汇干预政策的调控效果更显著.上述结果为防范化解金融风险和制定宏观政策提供参考依据.
Financial Risk Spillover between Capital Market and Real Sector and the Effect of Macroeconomic Policy Regulation
The report from the 20th National Congress of the Communist Party of China(CPC)underscores the importance of preventing systemic risk.To effectively monitor financial risk transmission within our country's capital market and real sector,this study utilizes the TVP-VAR model to compute dynamic spillover and absorption indices for the financial system's risk.Additionally,it examines the primary transmission pathways and the evolving patterns of financial risk during a specific period through directed network topology analysis.Furthermore,the study empirically assesses the regulatory impact of macroeconomic policies on the financial system's risk transmission using the TVP-FAVAR model.The findings reveal the following:(1)the financial risk transmission has intensified since 2015,and it exhibits nonlinear behavior across various capital markets and real sectors.(2)In the financial system,"the stock market → the real estate market"and"the government sector → the enterprise sector"are the main paths of risk spillover,and the risk spillover effect is significantly enhanced during the subprime crisis,in particular,the stock market,Covid-19 pandemic risk of the main spillover path is more complex.(3)Higher money market interest rates,decelerated money supply growth,and increased statutory reserve requirements have proven more effective in mitigating risk transmission during the subprime crisis.Additionally,fiscal policy adjustments and foreign exchange intervention policies have displayed notable effectiveness during the pandemic.These findings offer valuable insights for preempting financial system risk contagion while shaping macroeconomic policies.
