全球科学体系中的层级结构与开放结构——基于我国学术人才国际流动与知识生产的分析

The Hierarchy and Openness of the Global Science System:An Analysis Based on Chinese Scholars'International Mobility and Knowledge Production

通过对全球科学体系相关理论进行梳理,全球科学体系可被视为一个层级结构与开放结构并存的双重结构体系。基于这一理论,提出国际流动以及流动到位于全球科学体系核心位置的国家对我国学者知识生产的影响逐渐减弱的研究假设。基于我国四所“双一流”建设高等学校的学术人才国际流动与发表数据,通过在回归模型中加入流动类型、地域与世代的交互项,从时间与空间两个维度验证假设。这预示着,全球科学体系中的核心—外围层级结构对我国学者知识生产的影响呈减弱趋势;随着全球科学体系开放性的增强,我国在全球科学体系中崛起、向核心位置转移的可能性逐渐增大。

A review of the theoretical research into the global science system shows that the global science system can be viewed as a dual-structure system where hierarchy and openness coexist.Based on this theory,this study proposes a hypothesis that international mobility and those countries flowing to the core of the global science system have a weakening influence on the knowledge production of Chinese scholars.Based on the data on the international mobility and publications of academic talents from China's four"double world-class"universities,and the flowing generation and its interactions with the types and areas of mobility added to the regression model,the authors verify the aforesaid hypothesis in the dimensions of time and space.This reveals that the core-periphery hierarchical structure in the global science system exerts a decreasing influence on the knowledge production of Chinese scholars;with the openness of the global science system,China tends to be likely to rise in the global science system and shift to the core position.
