| 摘 要： | 城市土地集约利用状态是其宗地利用状态的集合,研究土地利用决策系统中各决策主体的行为特点和相互影响,对于改进土地利用决策,实现土地集约利用具有重要意义.本文通过土地利用决策过程的分析,明确决策主体和决策目的.然后,基于理性人的假设,借助于成本收益分析,分析土地开发商的行为；利用长期生产理论、土地报酬递减规律分析工业企业在土地、资本等生产要素上的投入变化,以及对土地集约利用的影响；同样,借助于成本收益分析和不同市场条件下的均衡,分析地方政府对土地供应总量的选择、对住宅和工业用地的供地策略,以及对土地集约利用的影响.研究表明:在技术条件和市场可接受的范围内,土地开发者的行为决策是尽可能地提高建筑密度和容积率,以提高土地利用强度；并且由于商业、居住用地对区位敏感,土地获取成本较高,表现更为突出.对于工业企业用地,随着土地相对价格的上升,会促使其增加资本、劳动等其他生产要素,并挖掘现有土地的利用潜力,但依据土地报酬递减规律,这种投入增加,以总收益增长为前提.地方政府在土地供应量上有突破用地指标多供应土地的冲动；对于住宅、商业用地的供应可凭借垄断市场条件,以较高的地价获得高额的土地收益；对于工业用地,受到买方市场的影响,会倾向于以较低地价吸引企业落户.为促进土地集约利用,地方政府应通过规划指标的限制和利用监管,规范土地开发行为,通过设定工业项目投资强度门槛,提高工业用地的集约度；同时,也需要通过有关法律、政策制度的完善,规范地方政府的决策行为. |

| Abstract: | The state of intensive urban land use is a collection of its land parcel use state. Research on the characteristics and mutual influence of decision subjects in land use decision-making is needed to improve land-use decisions and intensive land use. Here, we analyze land-use decision-making, the behavior of land developers by cost-benefit analysis, changes in the inputs from industrial enterprises by long-term production theory and law of land diminishing return, land supply choices of the local government, land supply strategies for residential and industrial areas, and the effects of intensive land use. We found that to improve the intensity of land use, the decision of land developers is to increase the building density and floor area ratio as much as possible in the range of acceptable technical conditions and the market. As for industrial land, the rise in relative land price means that capital and labor for production will increase. However, according to the law of land diminishing returns, increased investments take the total revenue growth as a precondition. The local government tends to supply more land: for residential and commercial land, it will obtain land revenue at a higher premium by virtue of monopoly market conditions but lower the price of industrial land to attract enterprises. In order to promote land intensive use, local government should standardize land development by restricting planning targets and regulating land use, and raise the intensity of industrial land by setting an investment intensity threshold. Local government should also regulate its decision-making behavior by improving related laws and policies. |
