Study on Endogenous Dynamics and Evaluation of Intensive Use of Construction Land Based on the Perspective of Elements

Based on the perspective of factors, this study used the literature method and comprehensive analysis method to draw on the basic theory, and deeply analyzed the endogenous dynamics and characteristics of the intensive use of construction land, and then discussed and constructed the framework of the construction land intensive evaluation system. An empirical study was conducted in nine cities (autonomous prefectures) in Guizhou Province. The conclusions show that: 1) The intensive use of construction land has its own objective laws. Its endogenous driving force includes population power, natural power and economic power. Policy systems, planning and control, and technological advancement are taken as its exogenous driving force through supply and demand mechanisms and aggregation effects. Mechanisms and factor substitution mechanisms lead to changes in the number and structural changes of endogenous motive elements, thus resulting in different intensive utilization types and intensive utilization levels. 2) The evaluation of construction land intensive degree is a comprehensive evaluation, and its expression is no longer confined to the intensive integration of single land elements, but should be an intensive ensemble of all factors that covers the degree of intensive population factors, the degree of intensive energy components and the degree of intensive economic factors. The evaluation index system should also include the population factor criteria layer, the energy factor criteria layer and the economic factor criteria layer. 3) The process of intensive land use of full element for construction land in Guizhou Province is relatively slow, and the intensive degree of construction land in most cities (autonomous prefectures) is in a fluctuation trend. The spatial pattern of intensive use of construction land in Guizhou Province have been optimized, and the spatial variability shows a trend of decreasing first and then increasing from 2010 to 2016.4) The levels of intensive utilization of nine cities (autonomous prefectures) in the province are dominated by low-level intensive use and low-level extensive utilization, and population factors and economic factors play a major intrinsic impetus. © 2020 Peking University.
