| Abstract: | The suburbs of megacities present a high dependence on the functional radiation of the central city,and there exist high relevance and competitiveness under the coordinated development of regions.A comparative study on the benefits of construction land in the suburbs of megacities is helpful to distinguish the development quality between different regions,so as to provide support for the rational allocation and prediction of regional resources in mega-urban areas.Based on the"core-periphery"theory,and on the basis of the existing construction land benefit evaluation method,this paper constructs a"horizontal-level"model between the same level areas(city suburbs and counties)and a"longitudinal-level"model(city suburbs and counties and central urban areas).On the basis of comparison of the benefits between the suburbs and counties of the city,the dimension of comparison of the benefits between the suburbs and counties and the central urban area has been introduced,and the"population-economy-space"multi-system comprehensive benefit evaluation method to make the quantitative evaluation of the model has been improved.The comparative research model for the benefit of construction land in the suburbs of megacities has optimized in the following two aspects:(1)the construction land benefit of the population-economy-space system replaces the previous method of comparison of the benefits of a single system of population and economy,which focuses more on the comparison of social benefits.(2)To add the vertical dimension compared with the central urban area and based on the judgment of the relative advantages of the suburbs and counties of the city,the changing trend in the regional hierarchy of megacities can be further clarified.This paper takes 11 districts and counties in suburban Tianjin as an empirical study,and obtains the following conclusions:(1)In terms of regional benefit levels,the benefit structure of Tianjin's suburbs has gradually changed from a single node to an axial expansion of the Beijing-Tianjin-Binhai New Area.The expected multi-core and multi-polar network space structure has not been fully established.(2)The benefit polarization in the central city is obvious.And the"flat"structure of benefits in the suburban and outer suburbs is significant.There is a great gap in benefit levels between suburban counties and central urban areas and lack of intermediate gradient levels.This feature is mainly manifested in the relative convergence of the benefits of the suburban and outer suburbs.Therefore,controlling the supply of land resources in the suburbs and optimizing the industrial development model of different benefit regions can effectively enhance the benefits of construction land in the suburbs and optimize the regional spatial development structure. |
