问题 单项选择题

如果企业的规模分布越来越不均等,则基尼系数()

A.小于0

B.趋向0

C.等于0

D.趋向1

答案

参考答案:D

解析:基尼系数:一种相对集中度的指标。基尼系数=均等分布线与洛仑兹曲线围成的面积/均等分布线以下的三角形面积基尼系数在0~1之间变动,当基尼系数=0时,表示洛仑兹曲线与均等分布线重合,即所有企业规模完全相等;当基尼系数趋向于1时,表示企业的规模分布越来越不均等。

     My grandfather is eighty years old. He always complains about how fast things have changed, and he

often says that life used to be better.

     "Families aren't what they used to be. A lot of families have broken up. If the husband and wife have

problems with their marriage, they no longer stay together. And mothers used to stay at home and take

care of their children, but now parents are both busy working. No one has time to look after children at

home.

     And the cars! No one walks anymore. More and more people drive. We used to walk five miles to

school on school days, even in winter. But now we don't. And in school, children don't have to think

anymore. In math class, for example, we used to add, subtract, multiply and divide by using our heads.

But now kids don't use their heads anymore. Instead, they use calculators.

     Most families have computers now. In the past we didn't have computers. We didn't even have lights.

My mother used to spend all day cooking in the kitchen. But now we don't often eat home-cooked food.

     And people talk less to each other than before. They are too busy to talk, too busy to eat, too busy to

think...Life used to be simple, but it isn't anymore."
