缩小贫富、城乡之间的差距是各国各地区的基本奋斗目标。各国各地区在寻求加快经济增长速度措施中都遇到了经济增长快与社会收入不相平衡的问题。例如 ,在巴西 1 96 6年 2 0 %最富裕户的平均收入与 2 0 %最贫困户的平均收入之比为 1 7:1。而到 1 980年 ,这个比例扩大到 33:1 1? The goal of narrowing the gap between rich and poor and between urban and rural areas is the fundamental goal of all countries and regions. All countries and regions in the quest to speed up economic growth measures have encountered rapid economic growth and social income is not balanced. For example, in Brazil, the ratio of the average income of 20% of the wealthiest households in 1960 to the average income of 20% of the poorest households is 17: 1. And by 1980, this proportion expanded to 33: 1 1?
