采用实地调研所得一手数据,运用净现值法分析了村委会或村民组出资钻建机井由农户承包经营、农户个体自建自营和村委会出资钻建但雇人管理3种经营模式下机井的投资效益。得出农户承包经营机井能获得一定的利润;农户个体自建并经营和村委会钻井并经营这2种投资模式只有在每次灌溉收费较高的情况下,经营者才可能盈利或不亏损。建议提高政府对钻建机井的投资补助力度,引导农村因地制宜地推进机井的产权制度改革,提高机井的建管水平。
Based on the first-hand data obtained from the field research, the net present value method was used to analyze the three operating modes of the village committee or villager group funded by the contractual management of farmer households, the self-construction of farmers and the investment and construction of village committees, Under the benefit of investment in wells. It can be concluded that farmers can get some profit by contracting and managing machine wells; farmers’ self-construction and operation and village committee drilling and operating these two modes of investment can only be profitable or non-loss with each irrigation charge higher . It is suggested that the government should increase investment subsidies for drilling and construction of wells and guide rural areas to promote the reform of the property rights system of the shaft according to the local conditions so as to improve the construction management level of the wells.
