中文摘要：
运用ROXY模型实证分析了1996--2010年中原城市群城市人口、第二产业和第三产业的空间发展态势演变特征。结果发现：城市人口与第二产业均呈收敛-加速极化-加速收敛一加速极化的空间演变特征，第三产业呈现逐渐减速极化的空间发展态势。由此判断中原城市群大城市在城市化进程中有其先天优势，可以引领其他城市加快城市化进程，但辐射能力非常有限，仍为弱核牵引。
英文摘要：
With the ROXY index, this paper analyzed the spatial evolving characteristics of the population, secondary and tertiary industries in Zhongyuan Urban Agglomeration during 1996--2010. The results indicate that both the urban population and the secondary industry demonstrated a convergence--accelerating polarization--ac- celerating convergence--accelerating polarization trend, and the tertiary industry showed a gradually decelerating polarization trend. On this basis, we can judge that the advanced city in Zhongyuan Urban Agglomeration has the innate gift in the urbanizing process, which can lead the less-advanced cities accelerate their urbanizing process. However, the radiating capacity of large cities is very limited as a weak core.
