Research into the Urbanization Levers of 31 Regions and Cities Based on the Developed Methods of Principal Component Analysis

This paper is to build the level of urbanization evaluation index system from the regional economy,population,infrastructure and lifestyle approach.Since traditional principal component analysis method does not consider the differences between original evaluation and the importance of the evaluation,it uses from the improved principal component methods to analysis the urbanization Levers of 31 Regions and Cities and ranks them.The concrete steps : standardized indicators of the original data;weight standardized data;the use of AHP to calculate the index weight;to get implant and eigenvector for the feature matrix;calculation of the composite ranking score;Finally,it can be seen that the level of urbanization in China is a greater difference.Coastal areas,Zhujiang River areas and Changjiang River areas develop better,northwest urbanization is slower.It presents the concrete reasons in objective economic and cultural environment for such differences and discusses the future development direction in those areas and gives some ideas for improvement.
