The newly added quota of construction land is very vital to the regional economic development.With the rapid growth of economy,the contradiction between construction land supply and demands has become further sharpened due to the scarcity of land resources. Therefore rational allocation of construction land is becoming more and more urgent. In order to allocate the newly added regional construction land rationally and scientifically, taking Jiangsu as an example,this paper first selects 13 factors as original indexes.Then principal components analysis method is applied to integrate these factors into three indexes,which are population resource, economic society,and urban development. Based on these indexes, the study applies AHP-GEM model to allocate the newly increased quota of construction land in Jiangsu Province.Result shows that the proportions of the allocation could be divided into four levels.In all of the three first level cities,Suzhou has the maximum allocated proportion (18.80%), followed by Wuxi and Nanjing with the percentages of 16.78 and 11.20 respectively.The second level consists of Nantong (7.93%) and Changzhou (7.81%).At the third level,Yangzhou, Zhenjiang, Yancheng,Taizhou and Xuzhou are allocated 6.03%,5.91%,5.51%,5.33%,and 5.00% respectively. Finally,Huaian,Lianyungang and Suqian belong to the forth level with the percentages of 3.65, 3.03 and 3.01 respectively. At the end of this paper,conclusions and suggestions for the newly added construction land allocation are presented.(1) The result basically reflects the increased construction land demand in a region.(2)AHP-GEMmodel combines the advantages of both AHP method and GEM method. Hence,it is more objective to allocate the newly added construction land quota using AHP-GEM model.(3)Choosing an appropriate index is important to apply this model.This index should better be a forecast value.(4)With minor modifications, this model can be adopted to allocate the newly added construction land at all levels, such as state, provincial,and county levels etc.
