摘　　要：经济政策的频繁变动,将对银行微观经营环境产生负面作用,进而影响银行发展资产证券化的动机。文章基于经济政策不确定性—银行微观行为变化—资产证券化发展的关联链条,考察经济政策不确定性对银行资产证券化发展的影响。研究发现:经济政策不确定性上升显著促进了银行资产证券化发展。进一步探讨该正向影响的内在机理后发现,经济政策不确定性对银行期限错配、风险承担及盈利水平等产生的负面影响,是推动银行发展资产证券化的重要动机,说明银行发展资产证券化的主要目的在于缓解政策频繁调整带来的负向冲击。文章为科学制定资产证券化发展策略,以及在新冠肺炎疫情导致政策频繁调整的背景下,通过资产证券化的发展来稳定银行行为提供了有益启示。Frequent changes in economic policies will bring negative effects on the microoperating environment of banks. In this context,the functional effects of asset securitization createconditions for banks to effectively resist the adverse impact of economic policy uncertainty. Inview of this,this paper examines the impact of economic policy uncertainty on the developmentof asset securitization of banks based on the related chain of “economic policy uncertainty—bankmicro behavior change—asset securitization development”. It is found that the increase ofeconomic policy uncertainty significantly promotes the development of bank asset securitization.Further,this paper discusses the internal mechanism of the positive impact,and finds that theadverse impact of economic policy uncertainty on the term mismatch,risk-taking and profitabilityof banks is an important motivation for banks to develop asset securitization,which confirms theoriginal logic of the article,that is,the adverse impact of economic policy uncertainty on themicro operating environment of banks constitutes a series of motives for the development of bankasset securitization,and fully explains that the functional system of asset securitization can be aneffective way for banks to cope with frequent policy changes. Finally,this paper studies thecorresponding heterogeneity characteristics,and finds that economic policy uncertainty promotesthe development of bank asset securitization,which is more significant in non-listed banks andsmall and medium-sized banks,because these banks lack sufficient adjustment means to adapt tothe unstable political environment,and they need to use the functional system of assetsecuritization to deal with economic policy uncertainty. Therefore,it has a stronger impetus forthe development of asset securitization.This paper holds that the main purpose of developing asset securitization is to deal with theuncertain external environment and its adverse impact on its own microstructure. Under thebackground that the outbreak of the C
