It establishes the three-dimensional model for these relations and points out that a good relationship between the construction enterprise and the construction employees in this crucial time of construction industry is a very crucial link of the achievements, as well as the well-being of the construction enterprises.展开更多
文摘Based on the theory that the management is about dynamic ＂relations＂, this paper analyzes the relationship between the construction industry and the ＂peasant laborer＂ in different stages, different contents and different aspects. It establishes the three-dimensional model for these relations and points out that a good relationship between the construction enterprise and the construction employees in this crucial time of construction industry is a very crucial link of the achievements, as well as the well-being of the construction enterprises.
