Hysteresis Quantitative Analysis of Urbanization Based on Gray Correlation Degree Model
用灰色系统分析法计算中国东中西部三省的工业化与城镇化滞后时间，发现全国滞后3年，且东部滞后最长、西部最短，原因与出口导向经济有关。
In this paper,industrialization rate and urbanization rate are chose to measure the level of industrialization and urbanization,selecting Shanghai,Hubei,Inner Mongolia from eastern,central and western,combined with national average level,using the gray system analysis methods to investigate relationship between industrialization and urbanization,calculating the gray absolute correlation degree,to obtain the different provinces' lag time of urbanization to industrialization and analyze its causes.The study showed that:China's lage time of urbanization to industrialization is 3 years;to different provinces,the hysteresis of Shanghai,Hubei and Inner Mongolia weakens successively.The reason is that eastern export-oriented industrial economy is developed,the international system providing market services to Chinese industrial product;while western export-oriented economy is weak,industrialization and urbanization are developing balanced,industrialization drives urbanization.
