自2007年金融危机以来，场外衍生产品再一次成为国际金融界关注的焦点。毫无疑问，场外衍生产品自身所有的特性在高度推动金融市场活力发展的同时也面临着因监管不力或信用支持体系执行不力造成金融市场的动荡。本次金融危机的源头就在于美国金融市场对场外衍生产品交易的监管不严。此外，我国作为新兴的场外衍生产品交易参与国在多次交易过程中多次碰壁，损失较大。究其根源，在于国内法与国际交易惯例的脱节以及国内交易商对国际市场的不了解。因此，针对场外衍生产品信用支持相关安排进行深入研究，特别是结合金融危机以来市场各方对该体系的重新认知与制度改革探索进行更深入的研讨将对场外衍生产品市场的发展有所裨益。文章结合场外衍生产品信用支持现有安排及其弊端的详细分析，提出了通过控制场外衍生产品交易商的自主权同时加强监管各方公权力介入场外交易的模式来保障场外交易的安全与稳定。本文对场外衍生产品信用支持体系的研究分为四个部分。第一部分作为对场外衍生产品信用支持体系的概述，从整体上对场外衍生产品所涉及到的概念性问题作了详细的阐述，分析场外交易公权力介入的必要性与可行性；第二部分是对场外衍生产品信用支持体系现行模式的说明，分别对ISDA协议与附件、美国、欧盟、日本、台湾等多地区的信用支持安排作了陈述和分析，通过分析现有制度来说明信用支持体系变革的必要性；第三部分则是对我国当前场外衍生产品信用支持体系相关制度的分析与评价，指出了我国现行制度的落后与改进之处；第四部分特别结合了金融危机影响给场外衍生产品市场带来的新挑战和国际社会信用支持体系的创新模式，并分析了该类创新模式的适应性和可行性。
