网络演化视角下科研人员国际流动对个体科研绩效的影响机制研究

Globalization is becoming more extensive and deeper. More and more researchers are moving around the world, and scientific mobility has become a research hotspot in recent years. The previous research on scientific mobility focuses on the factors affecting the scientific mobility from the perspective of social-cognitive, analysis on scientific mobility trends from the perspective of scientific collaboration, and impact of scientific mobility from scientific and technical human capital. For researchers in the academic network, the transnational flow is closely related to the evolution of the research cooperation network. However, the influencing mechanisms of scientific mobility on the scientific network’s evolution and individual scientific performance are not clear. This study will aim to solve this problem based on the network evolution perspective. First, this study will redefine the connotation of the concept of scientific and technical human capital based on evolutionary economics, as well as propose a theoretical framework of the influencing mechanisms of scientific mobility on scientific network’s evolution and scientific performance from the social network and human capital theories. Second, the ABM network simulation are used to investigate the impact of scientific mobility on scientific networks. Third, collect relevant data and further test the theoretical model by multivariate regression analysis and the structural equation model. Finally, the strategic choices and policy implications from both micro and macro levels are proposed to individual scientists and nations.

随着全球化日趋广泛和深入，越来越多的科研人员在全球范围流动，科研人员的国际流动问题已成为近年研究热点。针对该问题，已有研究从社会-认知角度探讨了科研人员流动的原因，从科研合作的视角测度了科研人员流动的现状和趋势，从人力资本角度解释了科研人员流动对绩效的影响等。对于处于学术网络中的科研人员来说，其跨国流动与科研合作网络的演化有着密切的关联，然而，从网络演化角度理解科研流动对个体科研绩效的影响机理仍不清。本研究基于网络演化的思想，研究科研人员国际流动对个体科研绩效的影响机理。首先，利用社会网络和经济学模型提出科研人员国际流动对个体科研绩效影响机理的理论模型;其次，利用ABM网络仿真方法模拟科研人员国际流动对科研网络演化和个体科研绩效的影响；第三，收集相关数据，用多元回归和结构方程模型进一步检验理论模型的有效性。最后，从个体微观和国家宏观两个层面提出科研人员流动相关问题的策略选择和政策建议。
