中国科协主席钱学森多次对决策科学化发表意见。最近,他在会见民德科普协会代表团时,谈了定量与定性相结合的研究方法。钱学森说,关于数学用于研究社会的问题,美国承认数学经济学的分析是靠不住的。我们也研究了这个问题,认为他们人为地把复杂的经济现象过度简化了。把它放到简单的数字框架里,这不是马列主义的,是主观的,不是客观的。所以我们有些同志走另一条路,采用定性和定量相结合的办法。就是在开始的时候,把熟悉经济的专家找来,让他们发表意见。但是专家的意见也都是局部的,因为他们是根据他自己的经验,受不同的时间、地点的限制,所以这位专家和那位专家的意见不完全一样。把所有 Qian Xuesen, president of China Association for Science and Technology, repeatedly expressed his opinions on the scientific decision-making.
