The Research on the Spatial Governance Tools and Mechanism of Megacity Suburbs Based on Spatial Evolution: A Case of Beijing

Abstract

The research on the spatial governance of the suburbs of megacities is of great significance for coordinating the spatial relationship between the central urban area and the suburbs of megacities, and implementing the regional functional layout of megacities. It is helpful to formulate scientific spatial governance strategies, and coordinate suburban space and central urban areas to achieve coordinated and sustainable development. This paper uses spatial form indicators to study suburban space governance from the spatial evolution characteristics of suburban construction land, constructs the relationship between different spatial evolution characteristics and the utility of spatial governance tools in the suburbs of megacities, and discusses the mechanism of suburban spatial governance tools. The study found that the spatial governance of megacities runs through the whole process of spatial evolution. Together with the three stages of space evolution, “space shaping, space restoration, space reconstruction”, we present three spatial governance mechanism types: “extensive development with positive guidance as the theme”, “exploratory adjustment with transformation practice as the theme”, “fine governance with management and control intervention as the theme”. In addition, the study also found that direct and indirect suburban space governance tools have different action paths and usage characteristics, and there is a synergistic mechanism between the two types of tools.
