The current cultural industry is an important driver of economic growth and has received widespread attention and emphasis from countries around the world. According to reports from the World Intellectual Property Organization (WIPO) and the United Nations Educational, Scientific and Cultural Organization (UNESCO), the global cultural industry output has reached 12 trillion US dollars, and has been steadily growing since 2000. In this context, exploring the market dynamics and financial investment strategies of the cultural industry has become a popular and intriguing topic. Although countries have different definitions, names, and scopes for the cultural industries, it can generally be divided into sub-industries such as film, broadcasting, cable, music, publishing, professional sports, performing arts, gambling, online games, theme parks, and fashion and luxury. Regardless of any of these cultural industry sub-industries, the supply and demand relationship is the core of market dynamics and directly affects the direction of cultural industry development and market opportunities. At the same time, financial investment strategies are the basis for investors to make investment decisions, and investment objectives are achieved through optimizing investment portfolios and reducing risks. Therefore, this work attempts to explore the market dynamics and financial investment strategies in the cultural industry. Through market supply and demand factors and general economic principles, it proposes differences and suggestions for the market dynamics and financial investment strategies of different cultural industry sub-industries.
