中文摘要：

以安徽省16地市连续6年的数据，运用分解后的TW指数进行测算，开创性提出“区域创新极化效应的城市贡献度”．并进行空间计量研究。结论认为：安徽省各地市创新能力呈“双核”分布，各城市对区域创新极化贡献度呈“工”字形分布，区域内创新能力高或低的城市并不一定对整体区域的创新极化有重要推动或拉低作用，缓解极化效应以创新能力居中的城市为重点，城市贡献度能更为精确地甄别区域创新极化效应的产生原因；此外，安徽省各城市的创新极化贡献度具有空间负相关特征，空间格局相对稳定，合肥、芜湖、池州组成了安徽省的创新极化中心，皖南创新极化贡献度分布具有交错性，皖北缺少创新增长极，安徽省创新极化贡献度由空间离散向空间集聚演变。

英文摘要：

Based on the data of 16 cities in Anhui Province for six years, we used the decomposed TW index, proposed the ＂urban contribution to regional innovation polarization＂ and carried out the spatial econometrics research. The results showed that the number of the innovation ability of cities in Anhui province was ＂dicaryon＂ distribution, and the urban contribution to regional innovation polari- zation was ＂I-section＂ distribution. The urban innovation ability in this region did not necessarily promote or push down the innovation polarization of the whole region. The remission of polarization effect should focus on the cities with medium innovation ability. The urban contribution to regional innovation polarization could accurately identify the internal reasons of polarization. In addition, the urban con- tribution to regional innovation polarization in Anhui Province had spatial negative correlation characteristics, and the spatial pattern was relatively stable. For instance, Hefei, Wuhu and Chizhou formed the center of innovation polarization in Anhui Province. The urban contribution to regional innovation polarization in south of Anhui Province was staggered, however the innovation polarization pole in Anhui Province was shortage. The urban contribution to regional innovation polarization in Anhui was evolved from Spatial Discrete to Spatial Agglomeration.
