The paper reviews the evolution of the enterprise growth theory, pointing out that its shortcoming lies in its stress only on what the enterprise possesses while ignoring what the customers need. In view of the characteristics of the medical industry, the paper argues that similar problems can also be found in the model for assessing the integrated strength of the hospital. It proposes the use of the model of the hospital's growth capacity in assessing the future development of the hospital. The model is composed of three aspects: material resources, manpower, and brand competitiveness. The paper also discusses the practical values resulting from the use of the hospital's growth capacity as the model for assessing hospital development.
