摘要
容积政策是影响城市更新收益分配的重要政策。以深圳为例,对城市更新中容积政策进行分析,指出在市场机制下,基于技术理性的容积规则可能产生激励不相容,带来城市更新中发展权益不平衡、改造利润差异大、容积率提高与城市功能结构失衡等问题,影响城市更新配置资源的效率和公平。为此,对城市更新合作改造模式进行分析,通过拆建比、拆赔比、可售房价单价、利润率等四项指标的城市更新收益分析模型,解析不同改造类型项目中各项指标的数学关系,分析城市更新中政府、市场主体、原权利人的经济关系。最后,从推进容积技术指标与经济指标分离、建立以拆建比为核心的权益建筑面积核算规则、加强拆赔比的统筹和引导等方面提出完善城市更新容积规则的政策建议。
Floor area is vital influencing factor of urban regeneration development gains.The article,based on Shenzhen experience analyzing the rule of floor area determination in urban regeneration,presents the evidence for the strong conflict between market-oriented and planning technology-oriented floor area determination,which brings the unequal development right among the subjects,the huge profit gap among different projects,the higher floor area ratio,and the subordinate functional type of urban construction,etc.The conflict has been proved not good for improving the quality and efficiency of floor area allocation.Therefore,this article analyzes the cooperative transformation mode of urban renewal,and uses an economic benefit analysis model based on four indicators:demolition and construction ratio,demolition and compensation ratio,saleable housing price unit price,and profit margin.It analyzes the mathematical relationship between various indicators in different types of renovation projects and examines the economic relationship between the government,market entities,and original rights holders in urban renewal.As a result of these investigations,suggestions,for instance,separating the market-oriented floor area and planning technology-oriented floor area,developing the demolition and construction ratio-based rule of floor area determination,enhancing the guidance of the demolition and compensation negotiation,are identified for improving the rule of floor area determination in urban regeneration at the end of this article.
