| Abstract: | Based on the analysis framework of spatio-temporal evolution of urban land use structure with the context of shrinkage, this study introduced the Information Entropy Model and the Shift-Share Model to examine the spatio-temporal evolution characteristics of urban land use structure in Northeast China, using panel data from 2000 to 2017. The dynamic mechanism of structural evolution of urban land use in Northeast China was analyzed by econometric model. The results demonstrated that: (1) the total area of urban land in Northeast China increased continuously since 2000, while the information entropy of urban land use structure increased firstly and then decreased. After 2011, with the improvement of diversity and equilibrium degree of urban land use structure, the order of urban land use structure has been enhanced and the leading role of single dominant land type has been significantly reduced. (2) The three types of urban land, i.e., land for public facilities, land for road, street and transportation and land for green space and square were growing, which is the main reason for the rapid increase of the total urban land area in the study region. (3) There exists significant spatial imbalance of competitiveness of different urban land types, which evolve constantly in different regions, and the overall spatial pattern is basically consistent with the distribution pattern of the two major urban agglomerations of central and southern Liaoning city groups and Harbin-Changchun megalopolis. Meanwhile the agglomeration effect of new-added urban land area is increasingly prominent. (4) The dynamic change of urban population, urban economic development, the upgrading and adjustment of industrial structure, and the improvement of urban living conditions all have significant positive impact on the dynamic evolution of urban land use structure in Northeast China. In the context of urban shrinkage, the effect of various factors is gradually weakened, and the binding force of national macro policies is increasing. Meanwhile, the demand for the improvement of urban public services has become the external driving force for the evolution of urban land use structure. To realize the overall revitalization of Northeast China, differentiated measures should be taken to reverse the trend of population loss, and boost the vitality of regional economic development. |
