The Third Plenary Session of the 20th Central Committee of the Communist Party of China, based on the construction of a socialist cultural power, made systematic arrangements for deepening the reform of cultural systems and mechanisms, and pointed out the direction of development. To promote cultural construction in the new era, we must prioritize social benefits and promote the unity of social and economic benefits. Further deepening the reform of cultural system and mechanism through the "dual effect unification" can not only ensure the healthy and orderly development of culture, but also stimulate the vitality of market entities and maximize the vitality of cultural development. Persist in putting social benefits first. The ideological nature of the cultural industry determines that cultural development must attach importance to social benefits and ensure its correct direction. Guided by social benefits, it is required to integrate this principle into all aspects of institutional design, policy implementation, resource allocation, and evaluation standards in the cultural field. It is not only necessary to strengthen the public welfare nature in the reform of basic public cultural services, but also to enhance the guiding power in the reform of the cultural market, avoiding the "flow first" and "excessive entertainment" that lead to the proliferation of vulgarity, vulgarity, and vulgarity. Highlighting the public welfare nature in deepening the reform of cultural system and mechanism can be guided and regulated through supporting mainstream works, strengthening content review, etc., to prevent the erosion of cultural ecology by the disorderly expansion of capital; Encourage social capital to participate more in projects that promote positive energy and achieve a win-win situation between social value and market value. For example, the movies "The Age of Awakening" and "Chosin Reservoir" adopt a multi-party cooperation model, introducing market-oriented operations, social marketing, etc., making the main theme more uplifting and positive energy more surging. Supported by economic benefits. Culture is an important component of a country's soft power and a significant driving force for economic and social development. To deepen the reform of the cultural system and mechanism, it is necessary to remove institutional barriers that restrict the vitality of cultural innovation. Not only should culture play a leading role, but it should also become an important support for economic growth, social progress, and international competition. Further comprehensively deepen reforms to unleash cultural productivity and promote high-quality economic and social development through high-quality cultural development. We should focus on strengthening digital reforms, promoting the integration of traditional cultural industries (publishing, film and television, performing arts) with 5G, AI (artificial intelligence), and metaverse, developing new formats such as digital cultural and creative industries, cloud exhibitions, and virtual performances, promoting the deep integration of "culture+technology", "culture+tourism", and "culture+manufacturing", and cultivating new momentum in the cultural industry. We should highlight the reform of the cultural market, unleash cultural productivity, expand the supply of high-quality culture, and stimulate the innovative and creative vitality of talents, market entities, and even the entire nation. The success of "Ne Zha: The Demonic Children Roar in the Sea" is a vivid example. With its creative transformation and innovative development of excellent traditional Chinese culture, as well as bold and innovative visual effects and breakthrough technology, it has broken multiple records in Chinese film history and become a widely concerned social and cultural phenomenon, demonstrating the thickness and depth of excellent traditional Chinese culture and effectively promoting Chinese culture to the world. At the same time, the diversified and three-dimensional development model of "movies+cultural tourism+derivatives" has successfully created the "Nezha" IP, driving the hot sales around the characters and the tourism boom of the story attractions. We should optimize the guiding mechanism for creative production, encourage creators to go deep into the fertile land of life, be good at drawing essence from the excellent traditional Chinese culture, and actively learn from the outstanding achievements of human civilization, so as to create more cultural masterpieces that integrate the ancient and modern times, connect China and the West, and achieve cultural empowerment, economic and social development. Realize the unity of social and economic benefits. Currently, promoting the "dual effect unity" of social and economic benefits is not only an inherent requirement of the objective law of cultural development, but also an established goal of deepening the reform of cultural system and mechanism. To deepen the reform of the cultural system and mechanism, we should optimize resource allocation and improve incentive mechanisms, open up a virtuous cycle in the cultural field of "winning the market with high-quality products, and then using the market to feed back high-quality creation", and achieve the unity of social and economic benefits. From a practical perspective, high-quality cultural products and services can achieve a win-win situation for both social and economic benefits. Excellent cultural works have profound ideological connotations, excellent production standards, and are favored by audiences and the market. For example, the Palace Museum has transformed its traditional operation mode, actively introduced market-oriented operation mechanisms, vigorously developed cultural and creative products of the Palace Museum, and cleverly used digital technology to enhance the visiting experience, greatly increasing the popularity of cultural relics and enhancing the public's recognition and pride in Chinese culture. At the same time, the cultural and creative products of the Forbidden City are selling well, the number of tourists has significantly increased, and ticket and derivative income has significantly increased, effectively driving the development of related industrial chains such as product design and production.
