土地开发整理项目投资估算修正系数的研究*

 为了完善全国土地开发整理项目建设标准和指导投资估算，本研究在对基准区（北京）项目划分的基础上采用统一的工程建设标准，通过分析基准区与各省（市、区）人工费、材料费和机械费之间的相互关系来获得修正系数和全国土地开发整理项目估算指标。该成果为解决全国各地由于不同建设标准而出现过大的投资差异提供依据。

Study on the Correction Coefficient of Investment Estimation in Land Exploitation and Reorganization

In order to perfect the construction standards and guide investment estimation of national land exploitation and reorganization, in this paper, the same engineering construction standard were adopted to analyze the relationship among the correlation of labor, materials and machinery, and on the basis of dividing in project of criterion area (Beijing), correction coefficient and estimate index of national land exploitation and reorganization were obtained. It could offer a reference for solving the oversized investment difference at different places because of adopting different construction standard.
