Abstract:

The development intensity of construction land is a comprehensive reflection of the regional construction land development degree and its carrying capacity of regional population, economy and society. We construct a theoretical framework and measurement model for the development intensity of construction land. Taking 179 counties in Northeast China as the research object, we use the spatial autocorrelation and spatial variogram to explore the evolution of spatial-temporal differentiation of the development intensity of construction land. We also use the ordinary least square (OLS) model and the geographically weighted regression (GWR) model to analyze the influencing factors and the spatial differentiation mechanisms of the construction land development intensity. The research reveals the following points: (1) The development intensity of construction land shows an increasing tendency from 2000 to 2015 and its spatial variance is significant. The interactions and linkage effects of the development intensity of construction land among different counties are obvious, but the spatial distribution of the development intensity of construction land tends to be unbalanced, and the distribution pattern of the cold-hot spots is basically consistent with the global variation and spatial heterogeneity. (2) The spatial variance of the development intensity of construction land is mainly influenced by the intensity of government financial investment, the investment intensity of land use and the structure of industry development in 2000, while the level of economic development has become a new factor during 2005-2015. (3) There is a correlation between the four influencing factors and the spatial pattern of the development intensity of construction land, but the influence of the four influencing factors in different counties varies greatly.
