The chart shows great changes in the number of museums and their visitors during the period from 2013 to 2015 . Accroding to the data given,what we cannot fail to see is that there is a sharp growth in the amounts of museums from 4165 to 4697 over the period from 2013 to 2015 , while it is also pronounce that the number fo their vistors inscreased sharply from 637.8 million to 718.1 million during this peroid .
At least two fundamental factors could be identified to contribute to this phenomenon . To begin with, it is widely admitted that with the rapid economic development in the whole social climate has been the dramatically upgrated living standard, which result in the common phenomenon that people in growing numbers can afford the once-deemed-expensive experience. In addition, there is no denying that the authorities concerned have issued a series of preferential policies to protect and promote the development of cultural industry , which encourages a widespread extension of visitors.
From what has been discussed above,we may safely draw the conclusion that this trend will certainly maintain for quite a while in the near future, which will be of great benefits to our country.
