Abstract [Objective] This paper reveals the evolution and regional differences of E-commerce policies for rural poverty reduction from 2008 to 2017. [Methods] First, we used the ToT (Topic over Time) model to investigate the probability distributions of time-topics and topics-words related to E-commerce policies for rural poverty reduction. Then, we analyzed the evolution of the policy contents by calculating the average intensity of topics in each year and extracted the top n topic words with the highest probabilities. Third, we divided the data from each province into the eastern, central and western regions, and then analyzed the regional differences of policies according to the probability distribution of topics and words. [Results] E-commerce policies for rural poverty reduction had the starting, exploring and developing stages. The eastern, central and western regions have different focuses on logistics, platforms and personnel training. [Limitations] The regional differences of E-commerce policies need more fine-grained analysis. [Conclusions] Compared with the traditional word frequency counting method, the ToT model effectively reveals the policy evolution and their regional differences.
