不同解释水平下工程变更决策的沉没成本效应分析
Sunk cost effects analysis of engineering change decision under different construal levels
摘要
Abstract
When construction enterprises face influence from market economy,natural environment,engineering condition,and policy adjustments,they would usually choose to change engineering to avoid risks and interference.However,changing frequently in engineering might cause sunk cost effect,which will influence decision makers' rational choice.As a result,both theoretieians and engineers in construction business pay attention to how to improve the decision level for sunk cost effect.Recently,most researchers have focused on two aspects:main effect on decision-making and negative influence on sunk cost effect.Few systematic theories can explain the sunk cost effect of engineering change decisions.The paper adopts the construal level theory to explain the sunk cost effect of level and situation by constructing a four table chi-square model,which discusses the decision criterion by decision-makers from the perspective of psychological distance in an experiment.It analyzes the consequences of different decisions to reveal the law of sunk cost effect in engineering change decision,which can provide theoretical guidance for engineering change management and avoid unreasonable sunk cost effect.The paper involves two parts.In the first part,the paper mainly builds a four table chi-sqnare model.Firstly,some theories,application status and engineering significance about construal level will be introduced.Secondly,the author designs an experiment to understand the sunk cost effect of decision makers in different situations (life situations and engineering situations) and different construal levels (self-decision and help others decide).Finally,the basic steps of four table chi-square test will be displayed.In the second part,the paper mainly discusses chi-square tests in four aspects (different construal level sunk cost effect in life situations,different constrnal level sunk cost effect in engineering situations,the relationship between construal level and sunk cost effect arisen from decision-makers,the relationship between situations and sunk cost effect arisen from decision-makers),and also analyzes the results.To sum up,construal level theory may reveal the law of engineering change sunk cost effect,and it can provide theoretical support for decision-makers to make reasonable engineering change decisions.Under low level construal,sunk cost effects will be generated when decision-makers face sunk cost in life or project situations.Under high level construal,sunk cost effect is generated easily in project situations but seldom in life situations.When decision makers face the same situation,sunk cost effect is generated more easily under low level construal than high level construal.When decision makers adopt the same construal level,sunk cost effect is generated more easily in project situations than in real life situations.关键词
