The study describes the development of health production functions and their application in the evaluation of the health impacts of investments in safe water and sanitation. For this purpose, data on the morbidity of waterborne diseases and diarrhoea were collected from medical records in the province of Central Java, Indonesia. A reciprocal production function was found to fit the data best. The health production functions exhibit constant return to scale, i.e., a simultaneous m-fold increase in both safe water and sanitation coverage produces a 1-1/m decrease in morbidity. Safe water was found to be more important for health than the sanitary disposal of excreta.
该研究描述了健康生产函数的发展及其在评估安全饮用水和卫生设施投资对健康影响方面的应用。为此,从印度尼西亚中爪哇省的医疗记录中收集了水源性疾病和腹泻发病率的数据。发现倒数生产函数最适合这些数据。健康生产函数呈现规模报酬不变,即安全饮用水覆盖率和卫生设施覆盖率同时提高m倍,发病率会降低1 - 1/m。研究发现,安全饮用水对健康比排泄物的卫生处理更为重要。
