An Analysis of Decoupling of Economic Development and Environmental Pressure Based on the Park Level: A Case of TEDA

Article Preview

Abstract:

Based on the decoupling elasticity model, an analysis is carried out on decoupling relationships between GDP and indicators of resource consumptions and pollutant emissions in Tianjin Economic-Technological Development Area (TEDA). Decoupling elastic coefficients (DECs) of GDP and energy consumption & water usage for nine years (2003-2011) along with the counterparts between GDP and emissions of COD & SO2 for six years (2006-2010), are calculated respectively. The results are as follows: first, the overall trends between development of GDP and intensity of resource consumptions and pollutant emissions per unit of GDP turn out to be almost perfect decoupling relationships. Second, the DECs of GDP and total energy consumption (TEC), along with weak or better decoupling in 6 of 7 years, displays in good condition from 2005 to 2011 and the ones of GDP and total water usage (TWU) improves a lot, compared to the period of 2004-2007, with a more favorable form of strong or weak decoupling during the period of 2008-2011. Third, strong (40%) or weak (60%) decoupling are witnessed among all the DECs between GDP and COD & SO2 for five years from 2006 to 2010. It is concluded that construction of eco-industrial park, the main practice of industrial ecology and theory of circular economy, accompanied with circulating fluidized transformation, is powerful driving force for TEDA to realize decoupling relationships between economic growth and environmental pressures and can contribute to achievement of decoupling at bigger level, country or regions.
