Abstract: Niche is an important index to measure the social function and status of literature.The niche of literature in a certain period,whether measured as a whole or in terms of a specific writer's works,indicates its social influence.The scientific nature of niche evaluation has been verified in traditional literature.Measuring the niche of network literature,it is found that the value of works,the fame of writers,the state of criticism,the state of reading and the media are not satisfactory.On the one hand,this is caused by traditional prejudice or reading inertia.On the other hand,it is caused by the low quality and large quantity of network literature.The typed routine writing of network literature leads to less masterwork,so the literary niche is not high.Therefore,the network literature should carry on the high-quality IP development,make more industry chain interaction of multi-cultural products such as film and television,games,produce more extensive influence,and enhance the niche in the cultural expansion.At the same time,network literature should enhance the subjective accomplishment of writers,improve the artistic quality of works,respect the active intervention of criticism,enhance the niche in literature itself,and make network literature grow from barbarism to a broad road.
