The most central part of the industrial transfer between Beijing, Tianjin and Hebei is the choice of the transfer industry and the overall layout and regulation of the industrial transfer of Beijing, Tianjin and Hebei. For the moment, the industry choice we adopt is to use industry gradient coefficients to figure out whether various industries in a region have advantages or where their strengths can be maximized. Through calculation, we can make more rational and rational planning arrangements for the industry selection and layout of the industrial transfer in Beijing, Tianjin and Hebei.
