Resource productivity in tianjin based on ecological footprint

Abstract

This paper regards the ecological footprint as the comprehensive indicator of natural resource to Calculation and analysis the resource productivity in Tianjin from 2000 to 2010. The results indicated that the resource productivity generally represented the trend of escalation in Tianjin. The resource productivity increased 1.66 times from1128.778 yuan per hectare in 2000-3005.613 yuan per hectare in 2010, the average annual increase value was 187.68 yuan per hectare. The GDP growth rate of Tianjin exceeded the growth rate of ecological footprint, but the growth rate of resource productivity is less thanGDP growth rate. So the pressure on the environment in Tianjin still increases gradually. The growth rate gap between resource productivity and GDP has narrowed since 2003. This is consistent with the fact of more pollution disposal investment, higher resource productivity and better environmental quality. © Springer-Verlag Berlin Heidelberg 2013.
