On Dealing With Openness And Self-Reliance In Development Of Science And Technology, Yungang Bao, Ninghui Sun
Bulletin of Chinese Academy of Sciences (Chinese Version)
China leaders have been always emphasizing both openness and self-reliance over the past decades. However, it is challenging for institutes and researchers to properly deal with the two requirements which are considered to be unachievable at the same time. In this study, we propose four openness modes as well as two principles for handling openness and self-reliance in the development of science and technology. This paper presents the case study on how Chinese computer pioneers made strategical decisions on the openness and self-reliance in the very early age of Chinese computer history. We also retrospect the practice of openness in …
