Gray Correlation Degree Study on Changsha-Zhuzhou-Xiangtan Urban Construction Land Structure and Economic Development

Abstract

Reasonable construction land structure can provide the material basis and bearing space for economic development, economic development can promote the rational allocation of construction land resources effectively. This paper uses information entropy model to analyze the evolution features of Changsha-Zhuzhou-Xiangtan (CZT) construction land from 2007 to 2013, and uses gray correlation model to explore the relationship between construction land structure changes and economic development. The results show that the change trend of equilibrium degree was consistent with that of the information entropy, but the dominance trend is the opposite. In addition, the study shows that the gray correlation degree of economic development and information entropy are within the range of 0.5–1. The analysis reveals that the most important factors affecting the change of construction land structure are urban resident consumption level, total retail sales of social consumer goods and per capita GDP. On this basis, firstly, it is recommended that the government should accelerate to make experiments on “multiple gauge unification”. Secondly, CZT should break the administrative division barriers and land market segmentation in CZT land market and reduce administrative intervention to achieve land market operation. Thirdly, the government should adjust and optimize the structure and spatial structure of urban land according to the city’s different property and function orientation. What’s more, it is suggested that the government need vigorously guarantee the land for economic development demands and carry out differential land supply policy for construction land. At last, the government should promote green cycle low carbon production mode and green consumption lifestyle for “Two-Oriented Society” construction.
