Research on the spatial evolution of resources and sustainable development of the spatial environment for the development of marine cities

Abstract

The marine economy constitutes a regional economic system centered around a specific marine geographical area, including coastal zones, and is dependent on marine resources and the environment. This study focuses on investigating the developmental spatial environment of marine cities, specifically examining the evolution of economic development capacity and resource spatial structure. Shenzhen is chosen as the research subject. Utilizing a set of comprehensive evaluation indices and a regression method based on the spatially expanded Tobit model, we conduct a thorough assessment of the city's economic development capacity. Additionally, an analysis of the spatial and temporal distribution patterns, as well as the changes in marine economic density and the evolution of marine city resources, unveils the profound alterations in the spatial structure of marine city resources during rapid economic development. This research not only provides a theoretical foundation but also practical insights for the sustainable development of marine cities.
