中部四大城市群（圈）外商直接投资的时空演化与竞争格局

采用熵指数与偏移一分享分析方法，对中部四大城市群近10年来外商直接投资（FDI）的时空演化与竞争格局进行了定量分析。结果表明，中部城市群FDI在不断增长过程中有分散化的总趋势，但城市群之间差异显著，具有阶段性特征；中部城市群FDI偏移增长量逐年增加，城市群之间的偏移增长量远大于城市群内部；高正偏增长城市前期主要集中在武汉城市圈、长株潭城市群，近期转向皖江城市带、东部沿江地带和中原城市群内沿京广、陇海线交汇一带。

Spatio - temporal Evolution and Competition Pattern of Foreign Direct Investment of Four Urban Agglomerations in Central China

In this paper, entropy index and shift-share analysis were used to measure spatiotemporal evolution and competition pattern of FDI of the four urban agglomerations in central China from 2000 to 2009. According to the survey, FDI in urban agglomerations was increasing with the over-all trend of decentralizing. The differences between four urban agglomerations were significant and phased. The growth shift of FDI in urban agglomerations was increasing annually, and the growth between urban agglomerations was much higher than that inside urban agglomerations. Cities which had positive and high growth shift of FDI at the early stage were mainly concentrated in Wuhan Urban Agglomeration and Cbangzhutan Urban Agglomeration, now shifting into Wanjiang City Belt, eastern region along the Changjing River and Zhongyuan Urban Agglomeration, along intersection region of Jingguang and Longhai Line.
