基于复合指标的郑州市域城镇化水平研究

对城镇化水平的测度，从人口、经济、社会文化、地域景观4个方面构建复合指标体系。采用主成分分析法，对郑州市域1990—2011年的城镇化水平进行综合分析，并对各分层指标进行数据标准化处理，研究结果显示郑州市城镇化综合水平保持较快的增长趋势，与人口城镇化水平存在显著的正相关，分层指标体系中首先表现为经济的增长与社会文化水平的提高，其次是地域景观的城市化，最后则是人口的城镇化，在城镇化进程中各分层指标体系所包含的各个指标在不同阶段所呈现的演变特点也是不同的。城镇化是一个复杂的过程，郑州市应调整产业结构，深化经济体制改革，逐步推进优质、高效的城镇化进程。

Research on Urbanization Level of Zhengzhou City Based on the Composite Index System

To measure the level of urbanization, start from these four aspects of the population, economic, so- cial culture and the geographical landscape to build the composite index system. Using the principal component a- nalysis method, make a comprehensive analysis of the level of urbanization of Zhengzhou city from the year 1990 to 2011, and makes a standardization of data processing to the indicators in each layer. The results show that the com- prehensive level of urbanization in Zhengzhou maintains a rapid growth trend, and shows a positive correlation with the urbanization level of population. Firstly, the hierarchical index system shown as the growth of the economic and the improvement of social culture, then is the urbanization of geographical landscape, the last is the urbanization of the population. In the process of urbanization, indicators in every layer present different evolution characteristics at different stages. The urbanization is a complex process; Zhengzhou should adjust the industrial structure, deepen the economic system reform and promote the urbanization process gradually.
