This paper mainly discusses the sales of welfare lottery tickets at the provincial level in 2020，including total sales，sales proportion，GDP proportion，lottery development index，lottery deviation index，per capita lottery and other related dimensions. By focusing on the analysis of the sales and other factors of China’s welfare lottery at the provincial level，we can understand the specific situation of the total sales，per capita sales，sales proportion and GDP proportion of welfare lottery in 2020，conduct comparative analysis in combination with the data of previous years，and find valuable conclusions based on the same established conditions. In addition，according to the “lottery deviation index” set in this paper，we can more intuitively see the relationship between welfare lottery sales and GDP in each province according to the calculation method of deviation index，and come to the conclusion that “in the western and northern provinces，the proportion of lottery sales in most provinces is higher than that in their provinces’GDP”，“in the southeast coastal and central provinces，The proportion of Fucai sales in most provinces is lower than or basically equal to the proportion of provincial GDP”，and points out the special situation of Zhejiang and Hainan in recent years.
