| In the context of the "14th Five-Year Plan",the goal of building a digital China is proposed,and the digital economy is frequently mentioned in China’s government work reports,indicating the arrival of the era of big data.The changes triggered by the digital economy are in the midst of vigorous development,and give rise to new industries,develop new markets,optimize the industrial structure and promote industrial development.In the report of the 18th Party Congress,the development goal of "cultural industry becoming a pillar industry of the national economy" was proposed,and in the report of the 19th Party Congress,the basic strategy of cultural construction in the new era was elaborated in greater depth,and the fundamental position of cultural confidence was highlighted.increased.The vigorous development of digital economy has become a key force to make the development of cultural industries high quality,and digital empowerment has enabled the development of cultural industry to realize the comprehensive integration and development of culture and technology.Therefore,it is of great importance to study the role of digital economy in the high-quality development of cultural industry.Firstly,based on the available literature,this paper systematically composes the relevant domestic and foreign studies on digital economy and high-quality development of cultural industry,including concept definition,measurement methods and influencing factors;on this basis,the influence mechanism of digital economy on high-quality development of cultural industry is analyzed theoretically.Secondly,based on the in-depth understanding of the research related to digital economy and cultural industry,a multi-indicator evaluation system is constructed,suitable measurement indicators are selected,and the entropy value method is applied to measure the development level of digital economy and the high quality development level of cultural industry in 30 Chinese provinces(excluding Tibet and Hong Kong,Macao and Taiwan)from 2012 to 2020,and the development status and development characteristics of both are analyzed.Finally,a panel regression model is constructed and empirically validated by fixed-effects model,mechanism analysis model and spatial Durbin model.The study finds that:first,the indicators of the digital economy and the high quality development level of cultural industry are both on the rise,and there is an imbalance in the development between regions,and the spatial characteristics of the gradient from east to west.Second,the digital economy can significantly make the development of cultural industries high quality,and it passes the robustness test.The heterogeneity test shows that the promotion effect is strongest for the eastern region,and the digitalization of the industry has a stronger promotion effect on the cultural industry.Third,the mechanism test shows that technological innovation plays a mechanism role and the digital economy can have a positive impact on the high-quality development of China’s cultural industry by promoting technological innovation.Fourth,there is a significant positive correlation between the digital economy and the indicators of high-quality development of cultural industries in terms of spatial characteristics,i.e.,they show spatial aggregation in geographic space.Fifth,after considering spatial factors,the digital economy still has a significant role in promoting the high-quality development of cultural industries,but the development of digital economy has a "siphon effect" on the high-quality development of cultural industries in neighboring regions.Therefore,corresponding policy recommendations are proposed:optimize the environment for the development of the digital economy,promote the digital transformation of the cultural industry,tap the innovation potential of the cultural industry,increase financial investment,and develop digital and cultural industries in each region according to local conditions. |
