英文文献摘要：
This study discusses the trend in Nigerian saving behaviour and reviews policy options to increase domestic saving. It also examines the determinants of private saving in Nigeria during the 1970-2007 period. It makes an important contribution to literature by evaluating the magnitude and direction of the effects of the following key policy and non-policy variables on private saving: Income growth, interest rate, fiscal policy and financial development. The framework for analysis involves the estimation of a saving rate function derived from the life cycle hypothesis while recognizing the structural characteristics of a developing economy. The study employs the Error-Correction Modelling procedure which minimizes the possibility of estimating spurious relations, while retaining long-run information. The results of the analysis show that the saving rate rises with both the growth rate of disposable income and the real interest rate on bank deposits. Public saving seems not to crowd out private saving, suggesting that government policies aimed at improving the fiscal balance have the potential of bringing about a substantial increase in the national saving rate. Finally, the degree of financial depth has a negative but insignificant impact on saving behaviour in Nigeria.

本研究讨论了尼日利亚储蓄行为的趋势，并回顾了增加国内储蓄的政策选择。它还考察了1970-2007年期间尼日利亚私人储蓄的决定因素。通过评估以下关键政策和非政策变量对私人储蓄的影响程度和方向，它对文献做出了重要贡献:收入增长、利率、财政政策和金融发展。分析的框架包括估计由生命周期假设推导出的储蓄率函数，同时认识到发展中经济体的结构特征。本研究采用误差修正模型程序，最大限度地减少估计虚假关系的可能性，同时保留长期信息。分析结果表明，储蓄率随可支配收入增长率和银行存款实际利率的上升而上升。公共储蓄似乎没有挤占私人储蓄，这表明旨在改善财政平衡的政府政策有可能带来国民储蓄率的大幅提高。最后，财政深度对尼日利亚的储蓄行为有负面但不显著的影响。
