The rapid development of the Internet has shifted reading from offline to online,and online literature has created a huge volume of works and cultural attention at an astonishing rate.In 2020,online literature plays its source and core role,driving the total output value of downstream industries such as film and television,animation,games,and audio reading to exceed one trillion yuan.At present,the most important direction of adaptation of online novels is film and television works,compared with the original market,film and television works have a greater user base and commercial potential,and further enlarge the source value of online literary IP.As "commercial capital" pays more and more attention to the online literature IP film and television adaptation market,there is a purchasing boom for IP adaptation rights,and the brilliant success of a small number of adapted films and televisions make the pricing of IP’s adaptation rights irrational,some people even believe that there are "bubbles" in the IP trading market.In this environment,how to reasonably price the adaptation rights of IP has become the biggest problem.Therefore,this thesis analyzes the current situation of China’s online literature IP adaptation market,and on the basis of previous research,establishes a value evaluation model for the IP film and television adaptation rights of online literature,hoping to provide a reasonable pricing reference for IP transactions in the industry and make a contribution to the development of the IP industry chain.This thesis first introduces the development status of China’s network literature IP film and television adaptation industry,reviews the researches on the evaluation method of online literature IP’s film and television adaptation rights at home and abroad,clarifies the meaning and value characteristics of the online literature IP’s film and television adaptation rights.After comparing the traditional three evaluation methods,this thesis decides to use the method of combining income method and analytic hierarchy process to evaluate the value of the film and television adaptation rights of online literature IP,first evaluate the value of its adapted film and television works,and then strip out the value of the film and television adaptation rights of online literature IP.Therefore,this thesis selects 9 factors that affect the box office revenue of adapted films,they are namely actors,directors,screenwriters,film genres,novel ratings,number of fans of novels,release schedules,distribution companies and the number of followers of the film,and uses them as dependent variables to construct a random forest model of the film box office to predict the box office revenue of the film.Then,on this basis,the revenue share attributable to the producer can be calculated,and the copyright value of the adapted film can be calculated using the revenue method,and then the hierarchical analysis method can be used to determine the value sharing rate of the network literature IP,so the value of film and television adaptation rights can be separated from the value of copyright in film adaptations.This thesis takes the classic novels "Schemes in Antiques" and "Ten Years of Loving You" adapted into films as examples,and uses the above evaluation model to evaluate the value of their film and television adaptation rights,and verifies the feasibility of the model.Finally,the full text of the research is summarized,and some countermeasures and suggestions are proposed,as well as the prospects for related research.After research and analysis,it was found that for the distribution of film box office,China has formed a complete set of processes,and the final income attributable to the producer is between 33% and 40%;according to the results of the random forest model,among the 9 factors that affect box office income,the number of novel fans and the number of movie followers are the two most important factors,the least important is the distribution company and the type of film,which shows whether consumers are interested in the movie and whether they are willing to watch the movie is crucial;through the evaluation of the case,it shows that it is feasible to predict the box office revenue of the movie with a random forest regression and to evaluate the value of the IP of online literature with a combination of the revenue method and the analytic hierarchy process.The evaluation model constructed in this thesis has certain practical significance.I hope that through the improvement of the evaluation model,I can contribute to the improvement of the evaluation system of film and television adaptation rights of China’s online literature IP. |
