摘要
本文基于“科学家在线”平台数据,运用复杂网络分析方法,按照年份分别构建2010—2017年间全国34个省份之间科研人员流动网络模型,测度并分析8年间科研人员流动的复杂性网络整体特征和随时间变化的趋势。研究发现:(1)8年间科研人员流动呈现整体较为明显的“无标度”特性,即北京、上海、江苏等经济科技发达地区不仅流入科研人员的规模较大,流出科研人员的规模也不小,但是全国大部分省份流动科研人员规模较为有限;(2)除了小部分省份之外其余省份的人员流入流出相对较为均衡,一些经济科技发达省份在一定程度上也是全国或本区域科研人员流动的中心节点;(3)从发展态势来看,8年间全国省级科技人员流动态势相对平稳,但是省份之间科研人员流动规模差距越来越明显,经济科技发达省份与其他省份科研人员流动的规模相比差距越来越大;(4)最为突出的变化是流动人员规模显著增加,人员流动更加便利。
Nowadays,scientific researchers are an important kind of economic resources and critical sources of creative power in the development of economy and society.With the increasing intense competition in science and technology,not only the government of our country has focused on attracting scientific researchers all over the world and puts it at the national strategic level,but most of provinces of China also have make relative policies for attracting scientific researchers in the nationwide and worldwide to improve the ability of scientific and technological innovation.It follows that a great number of scientific researchers move to other provinces in our country.The discussion on these topics is of great significance to optimize the system of scientific researchers policies,guide provinces to make policies for attracting and retaining scientific researchers,and construct a good environment for innovation,so that it must be explored with great conviction.To give a more confident and quantitative result,this paper establishes the networked model of scientific researchers mobility between 34 provinces of China during the years from 2010 to 2017 according to the database of scientist In with the help of complex network.In detail,34 provinces(including Hong Kong,Taiwan,Macao)are noted by nodes,directed scientific researchers flows are viewed as directed edges,and the number of mobile scientific researchers are abstracted into edge weights.According to the scientific researchers mobility network,it is straight-forward that a great number of scientific researchers entering into developed provinces and cities directly under the Center Government in China.From the power fitting functions for the cumulative in-degree probability distribution and the cumulative out-degree probability distribution the mobility network is scale-free from 2010 to 2017.According to the computing results of the entropies,it is obtained that the network of scientific researchers inter-provincial mobility in China is heterogeneous,which means that
