It is the fear of having to pay for expensive medical conditions that now drives individuals to accumulate substantial cash reserves. And focusing the favorable tax treatment on such major risk insurance would reduce the wasteful distortion to spend more on minor health conditions that do not stimulate household saving and do not need insurance protection.
如果中国政府果真使用这一方法刺激购买保险，应该将税收优惠限于对昂贵医疗情况（如手术或糖尿病治疗）的保险上。换句话说，能获得税收优惠的健康保险应该自付比例较高。目前，害怕昂贵医疗情况让个人不得不积累巨额现金储备。将有利税收待遇集中于这类重大风险保险能减少浪费性扭曲，以免将更多的钱花在并非家庭储蓄刺激因素、也不需要保险的次要健康状况上。
