Abstract

Prior studies primarily suggest that the generation of medical wastes maintains a positive relationship with national incomes. In contrast, higher incomes may lead to improved health status, consequently resulting in lower generation of medical wastes. Under this circumstance, an inverted U-shaped curve may be used to describe the generation of medical wastes along with economic growth. Additionally, illegal disposal is believed to have a high impact on human health. Thus, the purpose of this paper is to examine the presence of the environmental Kuznets curve for both the generation and illegal disposal of medical wastes by using a model of the environmental Kuznets curve. The results find the generation of medical wastes is positively affected by incomes, but this paper identifies the existence of the environmental Kuznets curve phenomenon for illegal disposal. Both the generation and illegal disposal of medical wastes are positively affected by medical capacity but negatively affected by medical policy. The primary contributions of this paper are three-fold. First, this paper is the first to focus on the existence of the environmental Kuznets curve phenomenon for both the generation and the illegal disposal of medical wastes. Second, this paper confirms the existence of the environmental Kuznets curve for the illegal disposal of medical wastes. Illegal disposal may be blocked when national incomes reach a specific level, and thus, the government may focus on the formulation of medical policy to encourage reduced demand for medical care. Third, this paper finds that the implementation of medical policy may have an important effect on inhibiting the generation and illegal disposal of medical wastes.
