摘要
本文以各省技术市场技术输出、流入量为分析指标,分别利用重心模型和统计地图方法,从动态和静态两种视角探讨1992-2014年中国技术转移流源、汇地空间格局特征及其演化规律,在此基础上利用标准差和变异系数揭示源、汇地内部空间差异的变化特征。结果表明:(1)技术源地重心移动轨迹经历了向西南再向东北再向西的转移过程,而技术汇地重心移动轨迹则呈现出向南再向北再向西南的发展趋势。(2)中国技术输出源地最初主要分布在东部沿海地区,但近年来在中西部形成了陕西、重庆、湖北、安徽等多个较大的输出源地;技术汇地最初同样分布在东部沿海地区,但近年来空间结构呈现向西、向南转移的趋势。(3)技术源地和汇地的绝对差异总体发展趋势为不断扩大,相对差异则在2006年之前均有扩大的趋势,而2006年之后源地开始趋于平稳,汇地不断减小。
This paper takes the output and input of technology markets as analytical indicators,and uses gravity center model and statistics map to study the spatial pattern and evolution trends of technology transfer source regions and sink regions from 1992 to 2014 in China from the dynamic and static perspective. And on basis of it,the paper uses standard deviation and variation coefficient to investigate the different degrees and development trends of source regions and sink regions. The results show as folows：firstly,the movement trajectory of gravity centers of technology source regions is first towards southwest,and then towards northeast,and finally towards west,while movement trajectory of gravity centers of technology sink regions is first towards south,and then towards north,finally towards southwest. Secondly,the technology source regions in China initially mainly locate in the eastern coastal areas,but in recent years form formed a number of large source regions in the central and western areas,Such as Shanxi,Chongqing,Hubei,Anhui; the technology sink regions in China also initially locate in the eastern areas,while the space stucture shows a trend moving towards west and south in in recent years. Thirdly,the absolute differences of technology source regions and sink regions are growing,the relative difference of technology source regions and sink regions are growing before 2006,while after 2006 the relative difference of technology source regions begins to become stable,and the relative difference of sink regions continues to decrease.
