There are different deformations in the implementation of different policies in county-level converged media center, such as symbolic policy implementation, selective policy implementation, copying policy implementation and wait-and-see policy implementation. Based on the analysis framework of three-level bureaucratic organization model, the reasons of such policy deformations lie in the attention allocation dilemma of county-level converged media center, which leads to the localization of policy implementation under multitask principal-agent; the incentive dilemma of the county publicity department, which leads to the path dependence and lack of innovation; the dilemma of control rights distribution of the provincial publicity department, which leads to the elasticity of policy implementation in vague goals and easy examination standards. The correction of policy implementation deviation needs to redistribute attention, establish a working mechanism and evaluation system that adapts to multitask; redistribute salary performance to stimulate innovation vitality; redistribute control rights to encourage positive policy innovation.
