摘 要:文中选取2010—2019年我国沪深A股上市公司为样本,运用固定效应模型,研究经济政策不确定性对企业风险承担的影响以及杠杆率的中介效应,分析经济政策不确定性、杠杆率、企业风险承担三者之间的关系。研究发现:经济政策不确定性会降低导致企业风险承担水平,企业会通过提高杠杆率间接地提升企业风险承担水平。进一步研究发现,相对于国有企业,经济政策不确定性对规模小、成长性差的民营企业风险承担水平影响更为显著。这意味着,去杠杆政策应当考虑不同规模、不同類型企业的特点,在政策制定方面要有一定的灵活性和弹性,避免“一刀切”的去杠杆政策,保持经济政策的连贯性、一致性,最大限度地降低政策改变使民营企业遭受影响,使微观经济主体了解未来政策走向。

Abstract:This paper selects Shanghai and Shenzhen Ashare listed companies from 2010 to 2019 as samples,uses the fixed effect model to study the impact of economic policy uncertainty on enterprise risktaking and the intermediary effect of leverage ratio,and analyzes the relationship among economic policy uncertainty,leverage ratio and enterprise risktaking.The results show that:the uncertainty of economic policy will reduce the level of enterprise risktaking,and enterprises will indirectly improve the level of enterprise risktaking by increasing leverage ratio.Further research shows that compared with stateowned enterprises,economic policy uncertainty has a more significant impact on the risktaking level of smallscale and poor growth private enterprises.This means that the deleveraging policy should consider the characteristics of different sizes and types of enterprises,have certain flexibility and flexibility in policy formulation,avoid “one size fits all” deleveraging policy,maintain the coherence and consistency of economic policies,minimize the impact of policy changes on private enterprises,and make microeconomic subjects understand the future policy trend.
Key words:economic policy uncertainty;leverage ratio;risk taking;risk management;fixed effect

2008年由美国的次贷危机引发的全球性金融危机,对世界各国经济产生了深刻的影响。我国出口业也受到了巨大的影响,农民工失业人数继续上升。2008年金融危机之后,我国政府大规模的投资和实施减税政策拉动经济回暖,也同时埋下了结构性矛盾的隐患,而杠杆率逐年趋势性攀升更是不容忽视。2020年新冠肺炎疫情在全球扩散蔓延,将对世界经济带来严重冲击,全球经济将萎缩3%,其影响程度不亚于2008年国际金融危机。这次疫情对中国和全球的社会和经济结构造成了严重的破坏[1]。……
