Art museum，as an important part of public cultural service system，is a crucial vehicle to protect people’s basic cultural rights and interests. At present，art museums in our country have outstanding performance in venues environment and service contents，as well as highlighted advantages of eastern and provincial venues，but there are issues such as low opinions of several factors in infrastructure，“polarization” distribution exposed in service level，eastern，central and western venues advantages stepped decline，and relatively behindhand service content of central galleries. In the future，free opening of galleries should innovate the mechanism of public input，increase social forces to participate in infrastructure construction，improve the performance evaluation system，improve the level of the peripheral extension of services，promote the “supply-side reform”，achieve equalization of public cultural services，pay attention to the special nature of the central region，ensure the synchronous development of services and hardware facilities and enhance the performance evaluation standards of galleries opening for free.
