Does environmental pollution inhibit urbanization in China? A new perspective through residents’ medical and health costs

Health problems caused by environmental pollution may affect the process of urbanization in China. Therefore, this study, against the backdrop of promoting new-type urbanization, evaluates the level of China's urbanization comprehensively using the fully arranged polygon graphical index method. It uses a dynamic threshold panel model to study the potential non-linear relationship between environmental pollution (wastewater, sulfur dioxide, and solid wastes) and urbanization under different health costs of residents. Our findings show that environmental pollution has inhibited the improvement of comprehensive urbanization, population urbanization, economic urbanization, and living conditions urbanization, but promoted living environment urbanization, in China. It is worth noting that with the rise in residents' health costs, the inhibiting effect of environmental pollution on comprehensive urbanization, population urbanization, economic urbanization, and living conditions urbanization in China has gradually increased, but on living environment urbanization, it has decreased.
