In order to study the structural change of the electronic publishing industry in Beijing, the prediction techniques of Markov and multiple regression analysis are applied to conduct research on the prediction problem of the product structure of the electronic publishing industry in Beijing, and the estimation model of Markov matrix of state transition probability is provided as well. The conclusion shows that the prediction accuracy of the prediction technique is quite high as the error of simulated result has been tested. The prediction technique is applied to forecast the product structure of the electronic publishing industry in Beijing from 2013 to 2017. The application of Markov prediction model in forecasting the product structure of the electronic publishing industry in Beijing has greatly expanded the fields where the prediction technique of Markov can be put into practice, and the data about the product structure of the electronic publishing industry in Beijing can hopefully offer reference for the development of industrial planning of publishing industry in Beijing.
