Decoupling between Construction Land Change and GDP Growth in China

Abstract

In order to analyze the relationship between urban construction land and economic development, and to know the similarities and differences of the relationship in different province in China, decoupling theory was introduced to analysis the relationship between construction land change and GDP growth. Research showed that, during 2003-2008, spatio-temporal difference was existed in every province in China about decoupling and coupling degree between construction land change and GDP changes. At the same time, there was also the leading type or major change trend. (1) During the 2003-2008, from the national scale, the interaction between construction change and GDP growth varied from weak decoupling state to the weak coupling condition. (2) Decoupling degree between construction change and GDP growth has a little difference in each provincial region in China, which showed majority continuous distribution in space. (3) Decoupling process between construction land and GDP growth may be turn into opposite direction, and the process was tortuous.
