Research on Kuznets Curve in Hubei and Gansu Provinces

Abstract

Due to the differences in geographical location, industrial structure and economic development in China, the level of economic development and pollution emission levels in different regions vary widely. Using the environmental Kuznets curve theory, this paper conducts an empirical study with Hubei and Gansu provinces as examples, and analyzes the relationship between wastewater, carbon dioxide and sulfur dioxide emissions and per capita GDP in the two provinces during 2005-2015. The research shows that the total amount of carbon dioxide emissions and per capita GDP in Hubei presents a classic Kuznets curve "n" curve, while the three indicators in Gansu cannot form a reasonable Kuznets curve relationship with per capita GDP. Combining the two provinces According to the specific conditions of different industrial development stages, relevant policy suggestions are put forward to promote energy conservation and emission reduction in the two provinces while promoting economic development, so as to achieve a reasonable development trend of the Kuznets curve and usher in a decline in pollutant emissions.
