: The trend of developing lunar natural resources is obvious. Determining the legal attributes of lunar natural resources can meet the dual needs of theory and practice. To clarify the legal attributes of the lunar natu? ral resources by stages will help fill the theoretical gap in the staged transformation of legal attributes and achieve an effective connection between the Outer Space Treaty and the Lunar Agreement. In the undeveloped stage, the natural resources of the moon belong to no owner based on pure natural endowment. In the development stage, the human community takes possession of the natural resources of the moon based on the principle of pre? emption so that it has the legal attributes of human common property.
