    Response Patterns of Vegetation Phenology Along Urban-Rural Gradients in Urban Areas of Different Sizes.Xue Luo, Yuqing Zhang & Dongqi Sun - 2020 - Complexity 2020:1-11.
    On the basis of MODIS Enhanced Vegetation Index time series data and multisource data, such as nighttime light data and China City Statistical Yearbook data, we investigated the differences in vegetation phenology along urban-rural gradients in urban areas of different sizes between coastal and inland cities in Liaoning Province, China. The results showed that the following: the iterative extraction of urban built-up areas using the threshold method based on nighttime light data combined with the definition of urban built-up areas had (...)

    Industrial Composition and Agglomeration Shadow: Evidence From China’s Large Urban Systems.Jiaming Li & Dongqi Sun - 2020 - Complexity 2020:1-11.
    New economic geography raises the question why the “agglomeration shadow” effect is significant in some urban regions but not others. This study attempts to answer this question in the context of China by examining the impact of industrial composition of core cities on regional urban systems. Based on the model of urban location from NEG, this study attempts to examine the population growth of six core cities and their urban systems in China. We find services exert a significantly negative effect (...)

    Evaluation of Urban Spatial Equality Based on Accessibility to Economic Activities: Beijing as a Case Study.Xinyu Yang, Fangqu Niu & Dongqi Sun - 2020 - Complexity 2020:1-12.
    Urban space is the spatial projection of various social and economic activities. Given the complexity of urban functions and the ongoing expansion of urban areas, the spatial differentiation of various economic activities within cities tends to become more and more clear; moreover, there tends to be spatial inequalities in resource allocation. Taking Beijing as an example, this study develops a spatial accessibility model at the town level by integrating the spatial distribution of economic activities with the transport system and evaluating (...)
