This article carries out a study on the possibility of making DP theory into a model from the point of technical development,and makes some further research into this theory. The conclusions include:the necessary condition for applying DP theory is that the surrounding area should have a higher tolerance to the pressure resulting from the development of the Pole. The recognition of this fact requires the government to focus more on the tolerance of the surrounding area rather than the developing effect only. The author also makes a detailed research on the scale limitation of the Pole selection,and finds out there exist positive correlations respectively between the newly_added investment and the dispersing effect,and the polarizing intensity,and the needed time for fulfilling this process.
