Abstract

A rational evaluation of the current impacts of urban industries is a prerequisite for their transformation and upgradation. Integrating the classical pressure-state-response (PSR) framework with the technology-resource-environment (TRE) perspective, we constructed a PSR-TRE urban ecological security index system for this study. Using the weights of different indicators for information entropy, we applied the weighted sum method to calculate a comprehensive urban ecological security index for Dongguan. We subsequently formulated five categories for assessing the security levels of the urban ecology. We also established a learning vector quantization neural network model to predict levels of urban ecological security in Dongguan under different scenarios. The results indicated that the urban ecological security level for Dongguan gradually increased during the period 1999–2015, showing the following progression: critically safe à relatively safe à safe. To a certain extent, this transformation indirectly reflects a successful process of industrial transformation and upgradation in Dongguan. We recommend a continued managerial emphasis on industrial transformation and upgradation within urban development planning. Moreover, reasonable guarantees should be provided to ensure the smooth progress of industrial upgrading.
