由于市场存在失灵,政府应该对市场进行干预,弥补其失灵。但政府干预成本巨大,且也可能失灵。自2007年初次贷危机浮出水面,到2008年9月金融危机全面爆发,再到危机逐步向实体经济蔓延以来,为应对经济危机,世界大部分国家都出台了经济刺激计划,对于避免震荡、稳定市场、恢复信心、促进增长起了重要作用。 Because of the market failure, the government should intervene in the market to make up for its failure. But government intervention is costly and may fail. Since the first loan crisis surfaced in 2007 and the financial crisis broke out in September 2008 and the crisis gradually spread to the real economy, in order to cope with the economic crisis, most countries in the world have introduced economic stimulus plan to avoid the shock and stability Market, restore confidence and promote growth has played an important role.
