To stride forward to the goal of the public cultural enterprise, and to think highly of the museum marketing issues, the purpose of this article is to point out the ultimate goal of museum marketing which are the new ways of thinking as museum brand valuations. Brand valuation is a technique of conducting value assessment of enterprises, and it is also a valuable type of measurement to assist the enterprises in reaching the market, based on the customer focus and therefore lead these tactics effectively. The brand valuation system, which focuses on the museums cultural enterprises, can benefit the value quantification and leading positive development in the correct manner. This article introduces some methods of brand valuation, and gives a model of the Interbrand brand valuation system, which is the mainstream of marketing, and to try to set up a proper musseum brand valuation. The article is based purely upon my own opinions. It will hopefully provide a new direction of thinking for issue discussion, as well as building up and guiding the management and marketing strategy amongst the museums.
