In recent years, cultural and creative industries have broken the constraints of resource and environmental pressure on sustainable economic development, become a new engine of economic growth and drive a new round of economic growth in advanced countries. The cultural industry with ‘knowledge’, ‘culture’ and ‘creativity’ as its main contents relies on Internet technology. Combined with trade, it shows strong economic potential. From the practice of South Korea, the success of cultural industry export trade has overcome the bottleneck of local resources, achieved sustained high-speed economic growth and greatly improved the country’s comprehensive competitiveness. Theoretically, culture has its rich connotation and extension, and its products and services have the characteristics of high permeability, high added value and high radiation. Therefore, the spillover effect of cultural export trade also has more scale, quality and sustainability. From the perspective of the spillover effect caused by the export trade of Korean cultural industry, this paper focuses on the important content of export products, film and television dramas. Through the analysis of ‘point consumption’ to ‘surface consumption’ brought by the export of popular Korean dramas to China, this paper verifies the generation of spillover effect by driving the export growth of tourism, beauty, food, mobile phone, automobile, food, clothing and other industries. At the same time, it examines some problems existing in Chinese film and television dramas, and provides some reasonable suggestions for the ‘going out’ of Chinese film and television dramas in the future.
