完善契税征管需要政府相关部门间通力协作。通过部门间信息化系统的联网协同合作、网络数据共享、相互监督制约,可以全面掌控税源,有效避免契税税款流失。本文提出了部门间联网协作、流程控制及数据传递的可行性方案。 Improving the deed collection and administration requires the concerted efforts of relevant government departments. Through inter-departmental information system networking collaboration, network data sharing, mutual supervision and control, we can fully control the tax sources, tax levied effectively to avoid deed. This paper presents the feasibility of inter-departmental networking collaboration, process control and data delivery.
