40 samples are selected from the collected China’s strategic emerging industry (SEI) policies on the level of central government from 2010 to 2013, and policy content analysis is applied to conduct a textual and quantitative research on them. Through constructing a two-dimensional analytical framework of “industry development dimension” and “policy support dimension”, this paper makes a statistical analysis on the frequency of certain words counts in China's SEI policies. The results show that China's SEI policies are characterized as focused keywords, innovation as the first key element, excessive planning and insufficiency of demand-based policy.
