Based on the big data index system of Chinese culture and tourism development，this report systematically analyzes the current situation of Chinese culture and tourism development from the perspective of big data. This report constructs a multi-level index system. The whole system consists of 3 first-class indicators，14 second-class indicators，30 third-class indicators，113 fourth-class indicators. The results of the report indicate that the overall development level of China’s culture and tourism industry is constantly improving，and the integration of culture and tourism has become the main trend. The TOP 10 in the overall index are Beijing，Shanghai，Chongqing，Tianjin，Jiangsu，Zhejiang，Guangdong，Fujian，Hainan and Shanxi provinces，while only the four municipalities have higher overall cultural and tourism development indexes than the average，it shows that the overall development of China’s culture and tourism industry is unbalanced and polarized. From the perspective of regional differences，the development of China’s culture and tourism industry in the east is far ahead of that in the west，the development level of the central and western regions is in the middle，while that of the northeast is weak.
