Evolvement of Spatial Pattern of TDI in Mainland China in Past 20 Years
分析了中国大陆东、西部TDI差异，用莫兰指数和热点分析研究1991年以来TDI空间格局演变，发现TDI从沿海向中西部扩散，空间自相关趋势下降，热点区向北移动但环渤海尚未成为热点。
This article analyzes the disparity of TDI between East China and West China,then uses Moran's Index and Getis-Ord Gi to further study the spatial pattern evolvement of TDI in mainland China since 1991.The results show that: ①There's a significant disparity of TDI in mainland China between East and West China,meanwhile,TDI is transferring and diffusing from coastal to mid-western.②The spatial distribution of TDI presents a significant spatial autocorrelation,however,this trend is dropping.③The spatial distribution pattern of TDI presents a circular structure,while the hotspot areas switching quickly.The hotspots spread towards north during past 20 years,however the Bohai Rim Region hasn't yet become the hotspots of TDI.
