This study took live stream policy network for example and explored the mutual interaction of ministries and commissions，local governments，Web self-discipline Alliance，live video platform，media organization and the public in this policy progress，by comprehensively applying research methods such as text analysis，policy process trace and depth interview.Consequently，we analyzed the integration and gambling between the thought of the party leading the media and the logic of platform governance and development of cultural industries under the background of media convergence.During the advanced stage of media convergence in the field of live video，we found that new media policy was confronted with big stress of regulation convergence in our country.Related policies excessively emphasized the limitation on new media platform without enough protection for the rights and interests.Furthermore，the common public and live video users were impeded in the participation of policies to some extend.Although the country integrated new media platform to regulation system，it also needed the new media platform to initiatively shoulder the regulatory responsibility and avoid the sole orientation of economic benefit.
