为此，较为实际的做法是加大不同档次划分比例的差距，例如，确定30岁以下记入比例为5%或10%，30~40岁为10%或15%，40~50岁为25%或30%，50岁以上职工为35%。

• For this, relatively effective way is to increase different class to differentiate proportional difference, for example, decide 30 years old write down scale to be below 5%25 or 10%25 , 30~40 year old for 10%25 or 15%25 , 40~50 year old for 25%25 or 30%25 , worker of 50 years old of above is 35%25 .
