本文依据住宅建筑不同楼层效用比的特性,构建投资报酬评估模式,选取12个位于郑州市的个案,分成楼层高低不同的A、B两组进行容积转移前后各种投资成本报酬率的变动分析,透过实质的成本效益分析,结论为:投资报酬率将随转移容积的增加而递减,风险则递增,且转移比率愈高,报酬率下降愈大。由本文评估模式的影响因子敏感度分析,经实证结果显示,房价对于投资报酬率的影响最大,其次为:容积加成奖励,降低融资贷款利率,免计法定停车空间。
Based on the utility ratio of different floors of residential buildings, this paper constructs the evaluation model of investment returns, selects 12 cases located in Zhengzhou city and divides into two groups of different levels of A, B before and after volume transfer, Through a substantial cost-benefit analysis, the conclusion is that the ROI will decrease as the transfer volume increases, the risk increases, and the higher the transfer rate, the greater the decrease in the rate of return. According to the sensitivity analysis of the impact factor of the evaluation model in this paper, the empirical results show that the housing prices have the greatest impact on the return on investment, followed by the volume bonus, reducing the interest rate on financing loans and exempting statutory parking space.
