At present, network literary creation and criticism can be said to present a landscape of flying together. Some scholars pointed out that network literature has formed three critical forces, namely academic criticism, media criticism and online criticism. The author believes that the "industrial economic review" from the field of industrial economy can be regarded as the fourth critical force. The emergence of this comment dimension is based on the significant contribution of network literature in the field of Pan entertainment industry and the cross-border empowerment and linkage adaptation of high-quality network literature IP. Network literature is not only independent in the vertical field, but also has become an important means of production in the pan entertainment field. Network literature is not just literature. As one of the important contemporary literary landscapes, network literature has been dissociated inside and outside literature with its virtuality, interactivity and cross-border derivative ability. It is obviously difficult for classical theoretical discourse such as Chinese classical literary theory and Western literary theory to interpret and evaluate network literature satisfactorily. Is it possible to find some new methods to evaluate network literature outside literature? In fact, no matter which dimension of comments, they are inseparable from the identity of online literature users and the value of works. I want to talk about the critical standards of network literature from the four value dimensions of "interesting, dramatic, informative and reasonable", and try to construct a relatively rough, but perhaps simpler and more effective evaluation system. "Interesting" is also the reading value of network literature. This is the basic creation requirement and basic value of webwriting. On the premise of correct values, if you are "good-looking" and "interesting", online works can basically enter the house. How can it be "interesting"? I think it provides readers with pleasure and satisfaction in character setting, plot compilation, vivid language and so on. User clicks, traffic and interactive comments are the most direct evaluation of whether an online work is "interesting". "Interesting" online articles satisfy the leisure desire of a certain audience with a sense of comfort, which is the basis for the prosperity of the big family of online literature. "Youxi" refers to the IP value of network literature. On the premise of "fun", if you can "play", this is IP in the conventional sense. IP value refers to the value potential of online text in the associated and derivative industrial chain such as film and television animation, game adaptation and peripheral development, in addition to online reading, audio works and offline publishing. This value is based on the integration and innovation of the type story of the online text and the type of story, relying on big data and ultimately relying on industry judgment, that is, industrial and economic value evaluation. Generally speaking, on the basis of "fun" and on the premise of accumulating a large number of fans, if there is a breakthrough in theme expression, characterization, story structure and type innovation, that is, the adaptation in cross text production has potential adaptation and interpretation space, that is, it has IP value in the general sense. Good IP is the treasure of multi part narration. American playwright Robert Mackey said that a wonderful story is like a symphony, in which structure, background, characters, types and ideas are integrated into a seamless unity. To find their harmony, a writer must study the elements of the story as various instruments of an orchestra - practice separately, and then play as a whole. Successful IP creation and operation is a complex integrated system. The network text of "Youxi" is ingenious in the construction of character relationship and the design of plot conflict. "Material" refers to the cognitive value of network literature, which is a higher level value than "drama". With large-scale and complex content, network literature plays an irreplaceable role in many aspects such as history narration, reality reflection, era record, social concern and future imagination. "Material" not only means that network literature can be used as adaptation materials and reproduction materials for the pan entertainment industry, but also that excellent network literature can help unite people's hearts, help the construction of socialist core values, and carry the cross-cultural communication mission of Chinese culture going out through "going to sea". "Youdao" refers to the artistic value or aesthetic value of online writing, which is the highest value of online writing, that is, the classic value. Samuel Johnson, an English critic in the 18th century, said: "Shakespeare's plays, according to the strict meaning and the scope of literary criticism, are neither tragedy nor comedy, but a special type of creation; they show the real state of ordinary human nature, both good and evil, joy and sorrow, complex and infinitely changeable." World famous literary works such as a dream of Red Mansions, war and peace and les miserables, which are highly comparable to the art of Shakespeare's plays, have the energy to surpass "era, race and environment". Good network literary works are the yardstick of type literature, and the significance and value of writers' writing also go beyond the category of type literature. Such works may not have the best commercial results, but they have the most classical direction. Although scholars have disputes about the year of the first year of network literature, the creation of network literature will be "young" and in development for a long time, and the theoretical research, appreciation and criticism of network literature will inevitably need to constantly introduce new methods and concepts. Only in this way can network literature develop across the border on the road of classics and become an important driving force for the construction of a cultural power and cultural output.
