从技术进步的角度对增长极理论模型化进行了探索和丰富。认为腹地在一定时间内能够承受其与增长极之间的经济发展差距增大所带来的压力，是增长极模式得以运用的一个必要条件，这就要求政府在考虑运用增长极模式时，不能只关注开发效果，更应该首先关注腹地的承爱能力；增长极的选择不是任意的，其规模不能超过某一定值，新增投资比例与采用增长极模式的预期开发效果（扩散效应）、增长极的极化效应强度以及极化效应完成的时间长短之间均呈现正相关关系。

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.
