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.
