Media Control and Market Segmentation in China

China has one of the largest media markets in the world. But most media providers in China - including all television stations and cable companies - are state-owned. This raises questions about efficiency of such systems. We take a novel approach to the subject by combining economics theory and a unique data-set on China's media. We address a set of non-traditional questions in the field of China's media: do state-owned media allow too many TV ads? Do they subsidize cable access from their ad revenue? Are there too many channels with duplication of media contents?
