文章以郑州市为例,主要研究了区域性中心城市辐射力指标体系,采用层次分析法对所研究指标进行了赋值。以此为基础,用裂点法对郑州与周边相邻、相关城市的不同城市要素相互作用的范围进行了分析。找出了郑州作为区域性中心城市的影响区域、发展优势和不足,并就提高郑州辐射力的途径、措施进行了研究。

Taking Zhengzhou as a case, this paper studies index system of radiant ability of regional central city and gives weights to indexes by AHP(analytical hierarchy process) method.Accordingly, the radiant scopes of different factors between Zhengzhou and other cities concerned are analyzed by using the theory of breaking point.As a regional central city, Zhengzhou's influential areas, advantages and disadvantage of developments are studied in this paper.Finally, the author gives the approaches and measures to strengthen the radiant ability of Zhengzhou.The conclusions are: 1) the comprehensive radiant ability of Zhengzhou shows stronger in the direction of SE-NW, and weaker N-S, which means that Zhengzhou is in a strong position in competiting with Hefei and Taiyuan, but in a weak position with Wuhan and Beijing-Tianjin areas.2) Zhengzhou is still a provincial central city, and its radiant ability as well as its influence is rather weak.The attractive ability to cities near the provincial boundary, such as Sanmenxia westwards, Xinyang, Nanyang, and Zhumadian southwards, is insufficient.Efforts should be made to realize the change from provincial central city to regional central city and central city of the big region.3) all factors of urban radiant ability is in the same level except that opening level is lower than provincial cities around Henan Province.The low level of opening not only restrains modulation and optimization of industrial structure and innovation of science and technology, but also influences cultural innovation, radiant ability, and especially, development of economy.4) Urban radiant ability includes other factors, such as politics and culture, besides factors mentioned above.Quantitive analysis and comparison have not been made due to difficulties of quantification of politics and culture.Urban political radiant ability can generally reach city's boundary of administration in current political system.At present, it is difficult to confirm the boundary of cultural radiant ability.This will be the goal of our near future.
