Study on the ZSG-DEA Model Considering the Limited Element Carrying Capacity of Each Decision Making Unit——A Case of Total Construction Land Index Allocation in Shanghai in 2035
The classical ZSG-DEA model is widely used in the studies of total carbon emis-sion quota and total pollutant emission quota allocation strategy due to considering the zero sum competition mechanism among decision-making units(DMUs).However,this model doesn't take into account the corresponding limited construction land carrying capacity in each research subareas which is regarded as a DMU,so it performs poorly when it is applied to the studies of total construction land index allocation strategy.Therefore,in this paper,the classical ZSG-DEA model was improved and the ZSG-DEA model considering the limited element carrying capacity of each DMU was proposed.Besides,this optimization mode was used to allocated the total construction land index in Shanghai in 2035.By optimizing the existing allocation scheme,the allocation strategy of making the construction land utilization efficiency of all Shanghai districts in 2035 reaching DEA effective was obtained.The proposal and application of this optimization model is an attempt to expand the application scope of DEA models.Under the principle of efficiency,the total construction land index allocation strategy obtained by using this optimization model is not only conducive to promoting the construction land fine management,promoting the transformation of the construction land management from"incremental control"to"amount control"and"reduced management",but also beneficial to provide a new framework for the studies of the total construction land index allocation strategy.
