本文认为对外资国民待遇的含义界定应从内涵和外延两方面结合做出。从内涵上讲,应采纳“不低于”标准;从外延上讲,应限于东道国具体承诺的“不低于”领域。外资国民待遇的含义影响我国对外资法的调整,在外资法的调整中,要准确把握外资国民待遇的含义,充分运用好外资管辖权。 This paper argues that the definition of the meaning of the national treatment of foreign investors should be made both in terms of connotation and extension. In terms of connotation, the “no less than” standard should be adopted; from the perspective of extension, it should be limited to the “not less than” field promised by the host country. The meaning of foreign national treatment affects our country’s adjustment of foreign investment law. In the adjustment of foreign investment law, we must accurately grasp the meaning of national treatment of foreign investment and make full use of foreign investment jurisdiction.
