Building a “sunshine government” （open government） is one of the major tasks of the Third Government of the Macau Special Administrative Region.By means of policy，institutions and tools，the construction of an open government is being attempted that will stimulate the formation of a new type of governance network based on openness，tolerance，rationality and harmony. However，the consciousness of the rule of law and the construction of legal institutions will become a major challenge during the course of building an open government. The realisation of an open government also depends on the joint effort by all members of the community.
