We have systematically explored the patterns, trends, and main characteristics of China’s ecommerce by relying on data on JingDong’s online sales. One of the most interesting findings is that China’s online consumer spending is positively correlated with regional income. In addition, people’s online consumer spending behavior exhibits regional heterogeneity and age cohort heterogeneity. People in the east region exhibit the strongest online consumer spending capacity. Finally, the most popular products sold online at JD are cell phones, followed by food and beverages, makeup and cosmetics, digital products, and lifestyle and travel goods.

How does the media help hold politicians accountable in countries with competitive elections has been well studied. However, whether and how media could discipline non- elected officials remain unclear. In this paper, I examine the effect of negative news coverage on political selection in China. To be specific, I evaluate how news reports on fatal coal mine accidents influence prefectural party secretaries’ likelihood of promotion. I find media coverage, rather than the coal mine accident itself, decreases the possibility of politicians’ promotion. This effect is more substantial when the media is non-local. Our results suggest that even with serious media control, there is publicity-induced accountability in China. The accountability-enhancing effect of media is driven by informing the public rather than informing the principle. I also propose that the M-form hierarchy of bureaucracy and economic decentralization create considerable discretion for media, which although limited, can hold politicians accountable.
