Spatial mismatch between economic development and pollution emission

Pollution was the byproduct of development. In the term of space, there was not a strict positive correlation between economic aggregate and pollution emission because of the difference of technical level, industry structure, and pollution treatment. It was to say, a nonconforming phenomenon could be observed between them spatially. The nonconforming phenomenon was called spatial mismatch. In order to analysis the spatial mismatch quantificationally, the spatial mismatch index(SMI) was established to investigate the spatial mismatches. Then, GDP and SO2emission were used to make empirical analysis. Finally, influence degree of some factors was studied. The results showed that in the year of 2000 to 2010,(1)With the shift of time, SO2emission tended to increase firstly and then decline. The emission increased from 1 965.8×104t in 2000 to 2 588.7×104t in 2006. In the year of 2010, the emission was 2 182.9×104t.(2)The spatial mismatches were founded between GDP and SO2emission to some extent. The SMI was0.25 or so.(3)During 2000—2007, SMI was enlarging, while during 2007—2010 was reducing.(4)Mismatch of a few provinces,such as Guangdong, Guizhou, Shandong, Shanxi, Jiangsu, Zhejiang, Inner Mongolia, contributed most on the mismatch between GDP and SO2emission.(5)The change of SO2emission shrank the mismatch. Nevertheless, unbalanced economic growth in 2000—2006 enlarged the mismatch and economic growth in 2006—2010 shrank the mismatch. The results should be important to economic structure adjustment and pollution reduction.
