摘要
提出以关键要素法重新对造价指数进行编制的问题,通过逐步回归分析识别关键要素和建立指数编制方程,并结合北京市房屋建筑工程造价指数进行实证验证。结果表明采用关键要素法编制的工程造价指数具有较高的准确性和合理性,在较大程度上解决了运用典型工程法编制造价指数带来的一系列问题。
This paper proposes the establishment of engineering cost index with the key factor method,and uses stepwise regression analysis to identify the key elements and build the index preparation equation. Finally,carries out the empirical verification in combination with the Beijing housing construction engineering cost index. The results show that the engineering cost index compiled by the key factor method has higher accuracy and rationality,which solves a series of problems caused by the typical engineering method to make the engineering cost index to a large extent.
