This study reveals the potential failure of the decision-making process of the national and public museum. The museum services are supported directly or indirectly by the government sector. this is because the museum produce public goods and merit goods. especially, national or public museums are operated by museum director who has been granted a public authority. so, the museums decision making is not a area of market-decision but a area of public decision. but, according to ‘Principal-Agent Model’ of public decision theory, the public decision can contain potential failure because of the ‘Strategic Thinking’ of decision maker. it will be a measure that resident council that represents stakeholder participate in decision making body of national and public museum. this is because the residents are direct or indirect stake-holders who has relationship with social utility of museum.
