Abstract: On the basis of the data of the contribution rate of foreign trade to economy in nine cities of Fujian Province from 2009 to 2016，the OWA operator weights method was proposed to allocate the weights of different years, which was combined with the TOPSIS model to make a systematic assessment of trade and economic benefits of the city. The spatial cluster analysis of the foreign trade of Fujian province economy contribution rate was also conducted. The conclusions are: the foreign trade and economic contribution rate of Quanzhou, Zhangzhou Fuzhou and Xiamen is lower than the city of Nanping, Sanming and Longyan.The city foreign trade economic contribution rate of Ningde and Putian is in the middle level. The conclusion after weight correction is consistent with the traditional TOPSIS evaluation. In addition, the contribution rate of the foreign trade to economy in various cities in Fujian shows a large spatial difference, to which the countermeasures are also put forward.
