摘 要:河北省农村饮水安全工程的供水模式以集中供水工程为主。集中供水工程的费用主要包括折旧费和年运行费;经济效益主要包括医疗费用的减少、副业收入的增加和其它生产性劳动收入。经济合理性分析拟采用项目经济评价指标体系,选用经济净现值、经济内部收益率、效益费用比和动态投资回收期等指标进行分析评价。分析结果表明,各项指标均满足项目合理条件要求,人均投资规模经济合理。The centralized water supply mode is the main mode for the rural drinking water safety projects in Hebei Province.The cost for centralized water supply mode is composed of depreciation charge and annual running cost.The economic benefits include the decline in medical expenses,and the earnings increase from bywork and other physical labor.Economic evaluation index system is adopted for the economic reasonability analysis and the choice of indicators includes the economic net present value,economic internal rate of return,cost-benefit ratio and dynamic investment recovery period.The analysis shows that each index fits the project requirement and the per capita investment is economically reasonable.
