我国建设用地资源错配的测算、因素分解及产出损失研究

Research on the resource misallocation calculation,factor decomposition,and output loss of the construction land in China

将建设用地这一生产要素引入到Hsieh和Klenow的资源错配模型,首先测算了2006-2015年我国工业、商服、住宅三类建设用地的资源错配指数,然后对其进行因素分解以探究错配来源,最后估算了建设用地资源错配所造成的产出损失率.研究发现,工业、商服、住宅三类建设用地均存在不同程度资源错配,工业、住宅用地存在过量配置,而商服用地则存在配置不足;自身价格偏低是工业用地过量配置的主要原因,要素边际产出偏低、用地价格偏高则造成商服用地配置不足,而畸高的边际产出是住宅用地过量错配的主要原因;若消除建设用地资源错配,可使经济产出增长30%左右.基于上述研究,本文收获了纠正建设用地资源错配的一些启发以供参考.

Based on the Cobb-Douglas production function,this paper introduced the construction land as the production factor into the resource misallocation model of Hsieh & Klenow.First,the resource misallocation index of the three types of the construction land,such as industry,commercial and residential,was calculated during 2006-2015.In addition,the factor of the resource misallocation index was decomposed to investigate its sources.Finally,the output loss rate which caused by the resource misallocation of the construction land was estimated.The result shows three types of the construction land all had different levels of the resource misallocation during 2006-2015.Industrial and residential land had excessive allocation,while commercial land had insufficient allocation.The low price of the industrial land was the main cause of its excessive allocation.The high price and the low marginal output of the commercial land were the main reasons of its misallocation.The excessively high profit margin was the main reason for the excessive allocation of the residential land.If the resource misallocation of the construction land was eliminated,the economic output would increase by about 30%.Based on the above research,this paper gained some inspiration to correct the misallocation of the construction for consulting.
