Abstract: The shortage of earth-s resources is becoming increasingly prominent, therefore, the moon has been studied and explored for its rich resources and near-earth nature. However, there is still not a comprehensive, uniform and binding legal framework in the international society. The paper cited the existing legal systems for the development of international public resources and moon resources. Moreover, it proposed that in the construction of the new legal system, different emphases in different phases of moon development should be fully considered. In the prophase, the Moon Development Authority should be a choice for the management of moon development activities; during the medium term, "the common heritage of intelligent beings in the universe principle," "the principle of Non-Military" and "the principle of environmental protection" should be consolidated and supported; in the post-development period, a compensation mechanism named Moon Development Fund Committee should be adopted to ensure the risks to be shouldered by space countries together. .
