| 摘 要： | 本文在构建城市区域创新发展综合指数的基础上,通过极化指数对城市区域的创新极化进行了量化研究,并以1998-2007年的城市数据为基础,考察了我国城市区域创新空间极化的动态变化趋势.研究结果表明:在我国京津冀、长三角、珠三角和成渝四大城市区域内,创新发展综合指数均存在显著的空间极化现象,且尤以成渝地区最为显著,长三角和珠三角次之,京津冀极化度最低.进一步研究极化指数增速的变化发现,变化趋势呈不对称的交替性上升下降运动特征,而且增速逐步趋近于0.

| Abstract: | The paper uses the special polarization index to work on the quantitative research of innovation polarizing trend on the basis of four urban regions. Based on the study of the data in 1998 - 2007, we find that the special innovative polarization has been happening in region of Beijing - Tianjin - Hebei, Yangtze delta, Pearl delta and Chengdu -Chongqing, and their polarization degrees increase one by one. Through the further study on the increasing rate of polarization degree, its change trend is increasing and decreasing alternately and approaching 0 gradually. |
