我国财政赤字和金融风险有着内在的联系,特别是与其货币供应量之间。本文截取1986-2006年的数据,通过协整和Granger非因果性检验得出财政赤字和M2存在着密切关系,并且通过VAR模型的构造对两者的稳定性进行分析,发现上述两者存在短期和长期的内在联动性。由此提出若干建议以避免财政和金融的共生性风险。 China’s fiscal deficits and financial risks are intrinsically linked, especially with its money supply. This paper intercepts the data of 1986-2006, through the cointegration and Granger non-causality test draws the conclusion that the fiscal deficit and M2 are closely related, and through the VAR model construction to analyze the stability of the two, we find that both exist short-term And long-term internal linkage. As a result, a number of suggestions were made to avoid the symbiotic risks of finance and finance.
