| The importance of cultural industry in the national economy has become increasingly prominent,and its high-quality development has been widely concerned by policies and theories.However,whether industrial policy can effectively promote the high-quality development of cultural industry has always been controversial.This paper takes the film industry as an example to discuss this problem.Firstly,this paper constructs a mathematical model based on oligopoly game,theoretically analyzes the impact of industrial policies on the film industry,and discusses the conditions under which industrial policies can effectively promote the high-quality development of the film industry.The results show that industrial policies can usually increase the number of films produced,increase the total box office of the film industry and expand the industrial scale,but it may not be able to effectively promote the high-quality development of the film industry.In order to increase the proportion of high-quality films and the box office of a single film,industrial policies are required to improve the consumer demand of the film market to a large extent,and at the same time favor the production of high-quality movies in terms of cost reduction effects.Policies that only focus on reducing industrial production costs may reduce the average quality of films and the average box office through the effect of increasing supply.These conclusions also apply to other cultural industries.Further,in order to find out whether China’s film industry policies have effectively promoted the high quality of the film industry,this paper matches and merges multiple micro data sets to form a unified data set at the individual film level,and on this basis conducts a quantitative analysis.The economic benefit of a film is measured by the box office of a single film,and the quality level of a film is measured by the film score.The measurement results show that the film industry promotion act has a significant positive impact on the box office and film score,while the implementation level policies,mainly the economic policies of subsidies and subsidies,have a significant negative impact on the box office and film score.The number of reviewers and the proportion of scores above three stars were used to replace the box office and rating indexes for regression,and the results showed that the above conclusions were strong and robust.The samples were divided according to different criteria,and the results showed that there was some heterogeneity among different subsamples,and the emphasis of industrial policy influence was slightly different,but the overall results were consistent with the baseline regression.These conclusions are of reference value to other cultural industries.Then,we use the number of reviewers and the proportion of scoring above three stars replace box office and film score for regression,and the results showed that the above conclusions have strong robustness.Finally,the samples are divided according to different standards and then the empirical analysis is conducted.The results show that there is a certain degree of heterogeneity among different sub-samples,and the emphases of industrial policy influence are slightly different,but the overall results are consistent with the baseline regression.These conclusions also have reference value for other cultural industries. |
