中国工业用地利用的数理分析与实证研究

中国工业用地利用效率低下,低成本过度扩张问题日益突出.文章通过构建新古典土地利用模型对最优工业用地出让数量、影响工业用地过度扩张的因素及工业用地过度扩张的工资效应进行了数理分析,并利用1986-2003年的面板数据进行了实证检验.数理分析和实证研究结果表明:地方政府追求工业总产出最大化导致工业用地低成本过度扩张.在土地收益被企业和政府攫取的情况下,工业用地出让数量的增长将导致居民边际工资收入下降.解决工业用地低成本扩张的根源在于调整土地收益分配格局并明确土地收益用途.政府通过提高工业用地出让价格来抑制工业用地扩张具有较长的政策时滞,暂停审批短期有效,但会招致剧烈反弹.

Mathematical and Empirical Research on Industrial Land in China

The use of industrial land in China is inefficient and the over-expansion of low-cost land is increasingly prominent.This paper examines the optimal grant amount of industrial land,the factors that lead to the extensive expansion of industrial land,and the wage effect caused by industrial land expansion,by establishing a new classical land-use model with a mathematical method,using the panel data from 1986 to 2003.The result shows that the maximum pursuit of industrial output of local government results in the extensive expansion of industrial land.If industrial enterprise and government obtain the profit of land,the marginal wage of residents will decrease with the increasing of the grant amount of industrial land.In order to harness the low cost and expansion of industrial land,the pattern of benefit allocation must be adjusted and the way to utilize the land must be clarified.There is long delay if the government raises the industrial land price in order to curb land expansion.The approval suspension might be effective in short term,but it will result in a dramatic rebound.
