高速公路后评价是项目建设步入完善、健全阶段的客观要求,后评价的基础和关键是构建一套系统的评价指标体系和方法。文章通过探索性因子分析建立了后评价指标体系,基于结构方程模型的原理和方法,构建了高速公路后评价模型,对评价模型进行了理论分析和实证检验。研究结果表明该模型方法不仅可以系统、定量的评价各个项目指标之间的直接和间接路径系数关系,而且可以明确评价项目、评价指标之间的因果关系,为提高项目的经济社会效益指明改进方向。本文为高速公路后评价提供了一套科学的综合评价体系。
Post-highway evaluation is an objective requirement for the construction of the project to go into a perfect and sound stage. The basis and key of post-evaluation is to construct a systematic evaluation index system and method. The article establishes the index system of post-evaluation through exploratory factor analysis. Based on the principle and method of structural equation model, this paper constructs a post-highway evaluation model and conducts a theoretical analysis and empirical test on the evaluation model. The results show that this model not only can evaluate the relationship between direct and indirect path coefficients systematically and quantitatively, but also can clearly appraise the causal relationship between project and evaluation index and point out the direction of improvement in order to improve the economic and social benefits of the project . This paper provides a set of scientific and comprehensive evaluation system for post-highway evaluation.
