Abstract
Infrastructure sustainability assessment plays an important part in promoting infrastructures’ achieving sustainable development. The result of sustainability assessment depends not only on indicator system but on indicators’ weight. Predecessors who studied infrastructure sustainability assessment mainly focused their studies on the construction of indicators , while there is few systematic and scientific methods on the determination of the weights of indicators comparatively, which directly affect the accuracy of the assessment result. On the basis of indicators developed by predecessors, project information was collected through Report of Environment Effect of Completed Project as the value of indicators. Then, PLS-PM is applied to verify the reliability of the construct of indicators and to analysis influence characteristic that indicators have on the assessment outcome based on item loadings and path coefficients. In the end, the weights of indicators are determined based on the path coefficients, which can be used as reference of weight to conduct infrastructure sustainability assessment (ISA).
