In the latter half of our Pinduoduo series, we explore Pinduoduo's long term future business strategies, including developing Pinduoduo's role as an AgriTech (i.e. agriculture and technology) platform in Part 3, and boosting user trust and satisfaction in this fourth and final installment. Specifically, in this article, we summarize the strategies Pinduoduo has implemented to increase user confidence and spending on the platform, as well as analyze their efficacies.
