基于交易成本理论和社会交换理论,分析了在不确定性和复杂性的外部环境的背景下机会主义和信任对工程项目成功影响的路径,并运用结构方程模型进行实证研究。结果发现:①外部环境不确定性对机会主义有显著的正影响,对信任有显著的负影响,但复杂性对机会主义和信任的影响并不显著;②机会主义与信任之间存在着显著的负影响;机会主义对项目成功有显著的负影响,信任对项目成功有显著的正影响;在低机会主义和高信任下项目成功取得最大值;③项目合作期限正向调节信任对项目成功的正影响。研究表明抑制机会主义和提高信任对项目成功有重要意义,这对提高工程建筑项目的效率有较好的启示。
Based on the transaction cost theory and social exchange theory, this paper analyzes the path of opportunism and trust on the success of the project in the context of uncertainty and complexity of the external environment, and uses the structural equation model for empirical research. The results show that: (1) The uncertainty of external environment has a significant positive impact on opportunism and a negative impact on trust. However, complexity has no significant effect on opportunism and trust. (2) There is significant difference between opportunism and trust The negative impact of opportunism has a significant negative impact on the success of the project, trust has a significant positive impact on the success of the project; under the conditions of low opportunism and high confidence to maximize the success of the project; ③ project deadline for positive adjustment trust the success of the project Positive impact. Research shows that restraining opportunism and improving trust are of great significance to project success, which has a good enlightenment on improving the efficiency of engineering construction projects.
