京津冀区域收入差距与环境质量关系的实证研究

Research on the relationship between income inequality and environmental quality in Beijing-Tianjin-Hebei Region

文中利用京津冀区域1994-2014年间的经济与环境数据,在收入差距视角下扩展EKC假说,对收入差距与环境质量间的关系实证检验。结果发现:1994-2004年间京津冀区域收入差距与污染物排放之间呈现的关系并不一致,且显著性不强;而2005-2014年间京津冀区域收入差距与污染物排放呈现正向驱动关系,表明2005年之后收入差距的影响作用加剧了京津冀区域环境质量的恶化。究其原因,与2004年"廊坊共识"达成以后,京津冀区域产业转移有着密切关系。因此,为保障京津冀协同发展国家重大战略实施,应抑制区域间收入差距扩大,防止"污染转移假说"效应,以实现经济与环境的协调发展。

In order to demonstrate the hypotheses of income inequality and environmental quality, this study ap- plied economic and environmental indicators in Beijing - Tianjin - Hebei Region from 1994 to 2014 to analyze the relationship between income inequality and environmental quality in the perspective of the income inequality according to the extended environmental Kuznets curve （EKC） hypothesis econometric model. It is obtained that the relationships between the three kinds of income inequality index and pollutant emissions were inconsistent and no obvious significance from 1994 to 2004. However, the relationship was positive from 2005 to 2014 in Beijing - Tianjin - Hebei Region. The results demonstrate that the influence of income inequality aggravated the deterio- ration of environmental pollution after 2005 due to industry transfer in this region. Therefore, it is necessary to effectively suppress widening income inequality and prevent pollution haven hypothesis effect to achieve sustained development of the economy.
