目前，我國大多數建築企業在人力資源管理上存在著：職位分析不到位，分析方法滯后；績效考核效果比較差，基本上是流於形式；薪酬水平長期偏低，內部公平性比較差；對員工的長期激勵不足，在人員的使用上存在重使用、輕開發的問題。如何建立一套完整有效的建築企業人力資源管理模式和激勵機制一直是建築企業改革的核心問題之一，也是解決我國目前建築企業效率低下，企業競爭力較弱的有效途徑之一。本論文運用規范分析和實證研究相結合的方法，針對目前我國建築企業人力資源管理在激勵和評價方面制度不健全的現象，研究如何建立有效的人力資源管理模式和激勵機制的問題。Among these factors, peer relationships have the greatest influence on students " prosocial behavior, and self - esteem has an indirect influence on students " prosocial behavior. according to the results of the regression analysis, the thesis builds a path model of influences of peer relationships, interpersonal trust, social desirability and self - esteem on students " prosocial behavior. based on the above conclusion, some suggestions are mentioned about how to improve the level of students " prosocial behavior in the thesis

在中國旅遊業轉型時期，傳統的點線旅遊方式正向板塊旅遊方式轉變，在這一轉變的過程中，原來組織方式中以旅行社作為經營主體的情況將發生變化，而旅行社始終處于旅遊消費中直接與旅遊者發生關系的末端，這符合供應鏈理論中核心企業逐漸向消費末端轉移的規律，因此本文仍對旅行社層面的供應鏈狀況進行分析，針對這些變化對轉型時期我國旅遊供應鏈的現狀、特點、規律、存在的問題和解決途徑以及優化機製作一初步探討。Sustainable development is the aim all the city planning experts pursued, in this paper a few advanced overseas planning principles are introduced, the process of the city development is studied and the utilization of urban underground space to promote the multi - center compact city mode is suggested
