国有企业同时具有公私属性，使得其参与国际经济法的行为性质难以界定；其中，国有企业代替政府实施国家政策和正常投资活动混杂的情况给争端解决机制中的投资仲裁属人管辖权的界定带来了挑战。本文通过分析近些年来的仲裁实践，提出在 ICSID 投资仲裁领域下，应当依据一般国际法关于国家责任的归因规则解决该先决性问题，以明确国有企业争议行为的性质， 帮助确定争议双方的属人管辖权要求是否得到满足。

State-owned enterprises (SOEs) have both public and private attributes, making it difficult to define the nature of their participation in international economic law; among them, the mixture of SOEs implementing state policies in lieu of governments and normal investment activities poses a challenge to the definition of jurisdiction ratione personae in investment arbitration. By analyzing the arbitration practice in recent years, this article proposes that in the field of ICSID investment arbitration, the preliminary issue of jurisdiction should be ascertained in light of the attribution rule of general international law on state responsibility, with the purpose to identify the nature of the disputed conduct of SOEs and help determine the jurisdiction.
