留学生流动视角下中国跨境人才培养的时空演化研究

In order to seize the commanding heights in the new round of technological and industrial revolution, the competition for talents is becoming increasingly fierce. Talents who master international rules and have the ability to communicate across cultures have become the focus of competition among countries. In the process of opening up and promoting the construction of the Belt and Road, China's demand for international talents has risen sharply. Sending students to study abroad is the best way for countries to cultivate international talents. Under the strategic background of accelerating the construction of the world's important talent center, the cultivation and flow of talents has become the focus and frontier of the government and academia. Based on the flow data of international students, this paper constructs a judgment model for the dependence of cross- border talent cultivation, and studies the spatiotemporal evolution of China's cross- border talent cultivation from the perspective of international student flow. The results show that: (1) The growth rate of Chinese students studying abroad is rapidly slowing down, and the spatial agglomeration trend of the global flow of Chinese students is constantly strengthening, mainly concentrated in the four major regions of North America, Western Europe, East Asia and Australia. (2) The growth rate of international students to China is gradually slowing down, and the sources of international students in China are primarily based on geographical proximity, with a high degree of spatial agglomeration, mainly concentrated in the surrounding areas of China such as East Asia, Southeast Asia, South Asia and Central Asia. At the same time, the number of international students from sub- Saharan Africa has gradually increased, and the source of international students in China has been significantly expanded in spatial scope. (3) The cross-border talent cultivation relationship between China and other countries has shifted from a situation dominated by symmetric dependence to a situation dominated by negative dependence. The positive dependence areas are steadily decreasing, mainly concentrated in North America and Western Europe, while the negative dependence areas are growing rapidly, gradually expanding from Southeast Asia and East Asia to Central Asia, South Asia and sub-Saharan Africa. This study enriches and expands on the theoretical and methodological integration of talent geography.
