Building "New Towns" from Industrial Zones: An UrbanSim Application in Yizhuang,Beijing
以北京亦庄为例，用UrbanSim模型模拟从开发区向新城转型中不同产业调整方案对土地利用和能源消费的影响，发现政府缺位时住房供需错配会降低安置率，而服务业转型有助于减少总能耗。
This paper takes Yizhuang,one of the three new towns in Beijing,as an example,and explores changes in land use and energy consumptions in different scenarios of industrial restructuring during its transition from the Beijing Economic and Technological Development Area to Yizhuang,the planned new town,using UrbanSim,a large scale urban model based on microsimulation.The results highlight the structural mismatch between supply and demand in the housing market in Yizhuang on condition that the visible hand of the government is absent.That mismatch gives rise to the decrease in the ratio of the number of placed households to that of planned households.Moreover,the restructuring of industries exerts significant impacts on the amount of energy consumptions in the new town;the structural change towards a service economy helps reduce the total energy consumption.
