Analysis of Industrial Economic Growth and Environmental Pollution in Tianjin Based on Tapio Decoupling Model

In order to accelerate the construction of a resource-saving and environmentally-friendly industrial ecosystem, this paper uses the Tapio decoupling analysis model to calculate the decoupling index of Tianjin’s industrial economic growth and the major environmental pollutants of the industry from 2005 to 2015 and analyze the decoupling status. The results show that the decoupling state of Tianjin’s economic growth and environmental pollution from 2005 to 2015 is generally in a strong positive decoupling and a weak growth decoupling, but the decoupling state of some environmental pollution factors has temporarily deteriorated. The relationship between industrial economic growth and industrial pollutant emissions has eased in the 12th Five-Year Plan.
