Introduction Modern health care services in Nigeria are provided by the Federal, State and Local Government Areas (LGAs) as well as private non-governmental (profit and non-profit) organizations. The three-tiers of government operates through a network of primary, secondary and tertiary level facilities. The primary health care is largely the responsibility of the LGAs with the support of state ministries of health. Secondary health care is available and provided at the State levels while the Federal Government is responsible for providing tertiary care. The referral system is to help ensure that the primary health care services are appropriately supported. The state and federal ministries of health review the resources allocated to, and the facilities available at the secondary and tertiary levels. The major aim of the referral system is to enable all Nigerians have easy access not only to primary health care but also to both secondary and tertiary health care. Healthcare in Nigeria is paid for on a cash and carry basis while out-of-pocket expenses dominate in households‟ payment for health care services. For instance, Ogunbekun et al (1999) indicated that 85 percent of the respondents in their survey sample reported paying for healthcare directly out-of-pocket, this was also supported by estimates from the Federal Ministry of Health (FMoH) (2003) which shows that over 70 percent of healthcare payments in Nigeria are made out-ofpocket. It is worthy to note that prior to this period, (that is, the 1980s) public sector health care services were virtually provided free of charge in Nigeria. With the introduction of user charges, there was an increase in the cost of care being incurred by the consumers and consequently, huge out-of-pocket payments. But given that consumer may have the willingness but not the ability to pay for these services and with huge out-of-pocket payments, there possibly will be a shift or a change in their demand for public health care services. One vital question in this regard is that of consumers‟ ability and willingness to pay these user charges, especially given the level of poverty that exists in the Nigerian economy. For instance, according to the World Bank, (1996), the severity of poverty as well as the incidence of extreme poverty increased significantly between 1985 and 1992. While, the National Bureau of Statistics (NBS) (2010) reported that the proportion of the core poor increased from 6.2% in 1980 to 29.3% in 1996 and then came down to 21.8% in 2004. The NBS report further shows that the proportion of Nigerians living in poverty is increasing every year as the incidence of poverty increased from 27.2% in 1980 to 46.3%, 42.7%, 65.6%, 54.4% and 69.0% in 1985, 1992, 1996, 2004 and 2010 respectively.

Abstract
Healthcare in Nigeria is paid for on a cash and carry basis while out-of-pocket expenses dominate in households’ payment for health care services as a result of user charges that were introduced in the early 1980s. This coupled with the persistent poverty level in Nigeria raises the question of consumers’ ability and willingness to pay these user charges. Accordingly, using primary data, this study examined the possible trade-off between user charges and demand for Public Health Care Services in Nigeria. The analysis showed that increasing user fees substantially reduced the use of government health facility by low-income earners. Thus, it was recommended, among others, that government should introduce price discrimination into user fees, to be set at marginal cost. This would help avoid the adverse distribution effects of user-fees, especially, on the lower income group.

尼日利亚的医疗保健是以现收现付的方式支付的,而自付费用在家庭支付医疗保健服务费用中占主导地位,这是1980年代初实行的用户收费制度的结果。这与尼日利亚持续的贫困水平相结合,提出了消费者支付这些用户费用的能力和意愿的问题。因此,本研究利用原始数据考察了尼日利亚用户收费与公共卫生保健服务需求之间可能存在的权衡关系。分析表明,增加用户费用大大减少了低收入者对政府保健设施的使用。因此,除其他外,有人建议政府对用户收费实行价格歧视,以边际成本确定。这将有助于避免用户费用对分配的不利影响,特别是对低收入群体的不利影响。尼日利亚的现代保健服务由联邦、州和地方政府区以及私营非政府组织(营利和非营利)提供。三级政府通过一级、二级和三级设施网络运作。在国家卫生部的支持下,初级保健主要由地方政府负责。二级保健由州一级提供,而联邦政府负责提供三级保健。转诊制度是为了帮助确保初级卫生保健服务得到适当支持。州和联邦卫生部审查划拨给二级和三级的资源和现有设施。转诊制度的主要目的是使所有尼日利亚人不仅能方便地获得初级保健,而且能方便地获得二级和三级保健。尼日利亚的医疗保健是以现收现付的方式支付的,而自付费用在家庭支付医疗保健服务费用中占主导地位。例如,Ogunbekun等人(1999年)指出,在他们的调查样本中,85%的受访者报告直接自付医疗保健费用,这也得到了联邦卫生部(FMoH)(2003年)估计的支持,该估计表明,尼日利亚70%以上的医疗保健费用是自付的。值得注意的是,在此之前(即1980年代),尼日利亚的公共部门保健服务几乎是免费的。随着用户收费的引入,消费者承担的医疗费用增加了,因此需要支付巨额的自付费用。但考虑到消费者可能有意愿但没有能力支付这些服务,并且需要支付巨额自付费用,他们对公共卫生保健服务的需求可能会发生转变或变化。在这方面,一个至关重要的问题是消费者支付这些用户费用的能力和意愿,特别是考虑到尼日利亚经济中存在的贫困程度。例如,根据世界银行1996年的报告,贫穷的严重程度和极端贫穷的发生率在1985年至1992年期间显著增加。而国家统计局(2010)报告称,核心贫困人口的比例从1980年的6.2%上升到1996年的29.3%,然后下降到2004年的21.8%。国家统计局的报告进一步显示,尼日利亚的贫困人口比例每年都在增加,贫困发生率从1980年的27.2%上升到1985年、1992年、1996年、2004年和2010年的46.3%、42.7%、65.6%、54.4%和69.0%。第七届国际商业和经济发展会议(ICBED), 2018年4月9日至10日,纽约,美国368贫困率的持续上升确实对尼日利亚消费医疗保健服务时支付这些费用的能力和意愿产生影响。支付能力和意愿(可能不会直接共变),因此决定了民众可获得的医疗保健的数量和质量。家庭可能都有支付的意愿,但却缺乏支付的能力,尤其是穷人。Yoder(1989)试图区分支付意愿和支付能力,他认为尽管它们可能不直接共变,但它们都受到一些因素的影响,其中收入和医疗保健质量是非常重要的。这被Gertler和Van dar Gaag(1988)等一些研究称为分配效应,因为征收用户费用增加了收入阶梯上半部分个人的福利和医疗保健利用,同时减少了收入阶梯下半部分个人的福利和医疗保健利用。 因此,该研究审查了在公共部门医疗保健设施中征收用户费用是否会导致该部门服务的使用量大幅减少,或者是否会导致所使用的医疗类型发生变化。本文的其余部分结构如下。紧跟着这个介绍性的部分是在第二节中包含的文献的简要回顾。第三节概述了方法和数据分析,而第四节讨论了研究结果。第五部分是对本研究的总结。2.1:文献简要回顾采用用户收费作为缓解保健筹资危机的一项战略,除其他外,由于其对保健利用的影响而受到质疑。Dor, Gertler和Van der Gaag(1987)和Gertler和Van der Gaag(1990)表明,在医疗保健消费方面,穷人对价格的反应是非穷人的两到三倍。因此,如果公共部门医疗设施的价格大幅提高,很大一部分贫困家庭将"移出"这一分部门。他们分别为科特迪瓦和秘鲁进行了研究。支持这一观点的其他研究包括:Litvack和Bodart(1993)对喀麦隆的研究;莱维和日耳曼(1994年)代表加纳;Ngugi(1999)代表肯尼亚,Amaghionyeodiwe(2007)代表尼日利亚。这些研究发现,用户收费的引入减少了对公共保健服务的使用,影响了消费者对保健服务的利用,特别是对穷人而言。Deininger和Mpuga(2003年)还发现,用户费用在决定获得保健服务的机会方面尤其重要,特别是对穷人而言。Alderman和Gertler(1989年)的研究证实了上述结论,该研究侧重于公共和私人保健对巴基斯坦儿童治疗的可替代性。Ching(1995年),其研究考察了用户收费对菲律宾各收入群体儿童保健需求的潜在影响。Moses等人(1992年)和世界银行(1994年b)指出,在肯尼亚内罗毕,在实行收费制度后,到公共性病门诊就诊的女性人数下降了65%,而男性人数下降了40%。在这方面,世界银行(1993)提出,除了富人,自付资金无法支付昂贵的医疗费用。相反,Lacroix和Alilhonou(1982)对贝宁的研究;Akin等人(1998年)对斯里兰卡的研究和世界银行(1987年)对菲律宾的研究表明,价格对医疗保健需求的影响相对较小。Nwabu和Nwangi(1986)断言,改善公共诊所保健服务的净福利效应取决于如何为这些服务提供资金。增加收入为这些服务提供资金的一种方法是对它们的使用收费。Ching(1995)使用医疗保健需求模型的混合/条件logit参数化来研究菲律宾不同收入群体的用户收费、儿童医疗保健需求和可及性,证实穷人比富人对价格变化更敏感。这对支付意愿有影响。因此,正如Mbanefoh, Soyibo和Anyanwu(1996)在估计尼日利亚医疗保健需求的研究中所断言的那样,用户费用是递减的,尽管他们没有对这一问题进行实证调查。Nwabu和Nwangi(1986)模拟了肯尼亚用户收费的福利效应。他们的研究基于另一种假设,即第7届商业和经济发展国际会议(ICBED), 2018年4月9日至10日,美国纽约369收费是对政府卫生服务的“纯税”,所产生的收入用于提高政府诊所的服务质量。它们表明,使用者收费造成的福利损失可以通过同时改善质量来扭转,从而将政府诊所的质量提高到与特派团诊所相同的水平。他们声称,收入足以实现这一壮举。然而,在所有政府保健设施中实行使用者收费所带来的福利收益很可能被随之而来的公平权衡所抵消(McPake, 1993年)。这种公平权衡,被Gertler和Van dar Gaag(1988)等研究称为分配效应,主要发生在穷人和富人之间。他们可能都有支付的意愿,但穷人却缺乏支付的能力。公平权衡被称为分配效应,因为征收用户费用增加了收入阶梯上半部分个人的福利和医疗保健利用,而减少了收入阶梯下半部分个人的福利和医疗保健利用。 Li(1996)在对玻利维亚医疗保健需求的研究中赞同这一论点,他警告说,虽然统一的用户收费可以产生可观的收入,但这可能会减少穷人对医疗保健的利用。因此,
