This paper investigates the management and sharing policy of research data in UK from three levels of government, research funding institutions and universities, and uses content analysis method to analyze the policy from six aspects: policy-making purpose, management content, management requirements, support and guarantee conditions, responsibility attribution and declaration of rights and interests. It is found that the different levels of policy have different emphasis and completeness, but in general constitute a complete policy system. Our government should increase support and guidance for research data sharing, improve and refine data management and sharing policies according to discipline characteristics and data differences, and clarify the rights and responsibilities mechanism, ensure the coordination between policies，and establish a sound supporting facilities to ensure the smooth implementation of the policy.
