Based on carbon emission data of 17 cities in Shandong Province in 2005-2009, this paper analyzes carbon emission economic efficiency. It conducts weight distribution by the Ordered Weighted Averaging (OWA) method, and takes systematic evaluation on carbon emission economic efficiency using TOPSIS method. In eastern coastal regions, including Dongying, Yantai, Weihai and Qingdao, the carbon emission economic efficiency is generally higher than inland regions of Shandong Province. The conclusion reached after correction of time weight is basically consistent with traditional TOPSIS overall evaluation, further proves validity of the evaluation. Finally, it gives recommendations for improving carbon emission economic efficiency in Shandong Province.
