The present study aims to explore the co-movement between urbanization and environmental sustainability for the period 1950 to 2014 using the wavelet coherence technique within the global framework. The wavelet coherence technique allows us to investigate both the long-run and short-term causal relationships between urbanization and environmental sustainability within the global framework. The findings reveal that (i) wavelet correlation from the global perspectives indicates a significant wavelet relationship between urbanization and environmental sustainability for medium- and long-term horizons; however, the correlations are not significant for the short-term horizons; (ii) significant vulnerabilities in urbanization and environmental sustainability are observed at different periods and different frequency levels; (iii) urbanization has reliable power for explaining environmental sustainability at different periods between 1970 and 2000. Based on our study, we suggest that global urban planners and policymakers should support modern environment-friendly technologies and renewable energies to control global CO emissions and pollutions created by industrialization; policy action to fight climate change is as well recommended as evidence supports to compact city theory.
本研究旨在利用全球框架中的小波相干技术，探讨 1950 年至 2014 年期间城市化与环境可持续性之间的共同演变。小波相干技术使我们能够在全球框架内研究城市化和环境可持续性之间的长期和短期因果关系。研究结果表明：（i）从全球视角来看，城市化与环境可持续性之间的小波相关表明在中长期存在显著的小波关系，但是短期则不显著；（ii）城市化和环境可持续性在不同时期和不同频率水平上存在显著的脆弱性；（iii）城市化在 1970 年至 2000 年期间的不同时期具有可靠的解释环境可持续性的能力。基于我们的研究，我们建议全球城市规划者和政策制定者应支持现代环保技术和可再生能源，以控制全球 CO 排放和工业化带来的污染；建议采取政策行动应对气候变化，因为证据支持紧凑型城市理论。
