Over the last 15 years, digitalization has changed and is changing the basic approach to the sustainable development of China’s cultural industry, which is undergoing a fundamental transformation process. However, a holistic analysis of this important process is still lacking. Mainly based on the relevant representative literature (2006-2020) in SCI/SSCI, CSCD, CSSCI databases and the latest statistics released by the National Bureau of Statistics of China (NBS) and China Internet Network Information Center (CNNIC), a systematic theoretical analysis and literature study of this process have been conducted. It is found that this process mainly takes place at the three levels of “Basic Technology - Industrial Structure - Spatial Distribution”. It first originated in the field of the basic technology of cultural content production, and then led to a dramatic change in the industrial structure, promoting the formation of a new spatial distribution pattern. At the level of basic technology, digitalization has become the main trend. At the level of industrial structure, industrial integration has become the main trend. At the level of spatial distribution, the spatial agglomeration has become the main trend. “Digitalization – Industrial Integration – Spatial Agglomeration” together constitute the core driving force for the sustainable development of China’s cultural industry. Due to the complexity of this issue, subsequent research should focus on developing an interdisciplinary analytical framework.
