A certain culture is a reflection of economy and politics under certain historical conditions, which in turn has a dynamic impact on economy and politics. Culture is the most essential feature that distinguishes human beings from other animals. In a sense, culture is the humanization and externalization of people, and the development of culture is the development of people. Man's cultural process is a long and complicated process, which is influenced and restricted by economic, political, social and natural environmental conditions. The development of culture is carried out by gradual accumulation, and the improvement of national quality and the goal of all-round development of people need long-term education, training and edification to achieve. On the one hand, culture, like fire, is the torch of national spirit, the horn of people's endeavor, illuminating the road of national liberation and inspiring people's fighting spirit; On the other hand, culture, like water, moistens all things and moistens them silently. It infiltrates people's hearts, nourishes people's spirits, sublimates people's thoughts, improves people's realm and cultivates people's sentiments in a subtle way. This is the unique function and special law of culture. Only by correctly understanding and grasping this law can we exercise correct and effective leadership over cultural construction, prevent and overcome the idea of quick success and instant benefit, and proceed from the fundamental interests of the party, the state and the people and the basic national conditions of the primary stage of socialism to solidly promote cultural construction. At the same time, China's socialist market economic system has been established and is being improved, and cultural construction is carried out under such a background, which is naturally inseparable from the market economy. What's more, the social and economic benefits of cultural products should be realized through the market. Therefore, to build an advanced culture, we must grasp the inherent requirements and operational characteristics of the socialist market economy, consciously follow objective laws, give full play to the role of the market mechanism, and develop and expand the cultural industry. Cultural construction should not only conform to the laws of spiritual civilization construction, but also conform to the requirements of the laws of socialist market economy. As spiritual products, cultural products have ideological attributes and social-oriented functions. At all times, we should implement the requirements of developing advanced culture and put social benefits first. Under the condition of socialist market economy, most of the production and dissemination of cultural products must enter the market, follow the market rules, and be transformed into mass consumption through commodity exchange, thus realizing its propaganda and education function. For popular cultural products, efforts should be made to organically unify ideological content, artistic quality and ornamental quality, and to unify the two benefits in quality and realize them in the market. However, some cultural products mainly provide public welfare services for the society, and their value cannot be simply measured by the market. To carry out cultural diplomacy, we should pay attention to deepening people's hearts. The essence of cultural diplomacy is spiritual communication and emotional exchange with people all over the world, and only on the basis of communication and understanding can we gain understanding and respect. We strive for a peaceful and good international environment and surrounding environment through cultural diplomacy, win the hearts of the people, safeguard world peace, promote common development, and build a well-off society in an all-round way, and play an irreplaceable role in economic and political diplomacy. In recent years, China has held a series of large-scale cultural activities, which gradually formed a brand. Taking advantage of the National Day, the establishment of diplomatic relations day, the sister city conclusion day, the Spring Festival and other opportunities, various cultural exchange activities were held, which not only publicized contemporary China, but also brought China closer to the world. Cultural exchange has also played a positive role in promoting the spiritual return and cultural identity of compatriots in Hong Kong, Macao and Taiwan. We persist in taking the government as the leading factor, taking non-governmental exchanges as the main body, taking the market mechanism as the lever, giving full play to the enthusiasm of the central and local governments, combining government exchanges with non-governmental exchanges, combining cultural exchanges with cultural trade, vigorously implementing the "going out" strategy, and striving to reverse the serious deficit in cultural trade. In foreign cultural exchanges and foreign cultural trade, we should not only safeguard China's cultural sovereignty, maintain the independence of our ideology and culture, and ensure China's cultural security, but also constantly expand the influence of Chinese culture and expand the export share of our cultural products and services. To carry out cultural diplomacy, we need to always stand at the forefront of world cultural development, grasp the latest trends and trends of international cultural development, carefully analyze and study various cultural phenomena and trends of thought, pay attention to drawing on and absorbing the world's beneficial cultural concepts and ways and means of producing and serving advanced cultural products, promote China's cultural construction, and continuously enhance the overall strength of Socialism with Chinese characteristics's culture.
