目前的国际投资法体制面临实体、程序和决策机制等多重挑战,面对彻底废除论、维持现状论和改革完善论等多种主张。尽管存在退出或废除投资条约和拒绝执行仲裁裁决的极端个例,但主流趋势是在实体、程序和决策机制上限制外国投资者保护和增强东道国主权公共规制。国际投资法体制将会继续在实体、程序和决策机制层面平衡外国投资者、东道国以及其他利害相关者的利益、价值和要求,走向包容市场自由、政府干预和社会参与的国际投资法体制。 The current system of international investment law is faced with multiple challenges such as entities, procedures and decision-making mechanisms. In the face of such arguments as the complete abolition of the theory of the status quo and the theory of reform and perfection, the international investment law system is faced with numerous challenges. Despite the existence of extreme cases of the withdrawal or abrogation of investment treaties and the refusal to enforce arbitral awards, the main trend is to limit the protection of foreign investors and the strengthening of public regulation of host country sovereignty over entities, procedures and decision-making mechanisms. The system of international investment law will continue to balance the interests, values ​​and demands of foreign investors, host countries and other stakeholders in the substantive, procedural and decision-making mechanisms and to follow the international investment law regime that embraces market freedom, government intervention and social participation.
