潘建伟曾经在一次演讲中讲道:回顾历史,我们可以深刻理解,科学技术对一个国家的重要意义,感受到科技工作者所肩负的责任。据统计,清代我国的国民总产值占世界经济总量的30%以上,但由于长期科技落后等诸多原因,使得中国遭受西方列强近百年的侵略,社会经济也一再衰落,到建国伊 Pan Jianwei once said in a speech: Looking back on history, we can profoundly understand the importance of science and technology to a country and feel the responsibility of science and technology workers. According to statistics, in the Qing Dynasty, the gross national product of our country accounted for more than 30% of the total world economy. However, due to many reasons such as the long-term backward technology, China suffered from the aggression of the Western powers for nearly a hundred years and the social economy declined again and again.
