金融衍生品经济无限制膨胀是美国次贷危机、环球金融震荡的直接祸根

美国“次贷”危机的核心特徵是：“次贷”转为“次债”CDOs；从间接融资领域追入直接融资的资本市场领域；从美国金融市场跨越到国际金融市场；骨牌效应前所未有，皆归因于近年来美国金融衍生品经济的无限制膨胀。金融衍生品不断创新与发展基于上世纪70年代金汇兑本位货币制度的崩溃，是自由市场经济为解决自身矛盾在金融领域高度发展的必然结果。金融衍生品经济为发达市场经济运行带来了正效应，但其本质是虚拟经济运行，对实体经济必然呈现反向“锋刃”。近15年的环球金融风暴，无处不见发达市场经济金融衍生品泛滥的身影；规避的根本途径是：第一，约束发达市场经济国家金融衍生品经济的发展规模，其实体经济总规模应是“虚拟经济”交易总规模的理论最高值；第二，重建环球市场经济体系中的货币稳定机制与汇率稳定机制，建议建立环球中央银行，并构建环球中央银行的“基础货币”即国际通行储备货币与国际金融平衡调节货币。
