补充资料:地价评估趋势评估法
地价评估趋势评估法
【地价评估趋势评估法】土地价格在一定的时间内由于受诸多因素影响,呈周期性的波动,但总趋势是上升的,因此,利用一定的数学模型,就可以求算出地价,一般要通过回归分析,找出土地价格与时间变量之间的函数关系,画出地价发展变化趋势图形,然后建立数学模型,进而推算出地价。若以Y代表历年地价,X代表时间,丫代表地价,其关系式为:y‘=a+bx(a、b为常数)。采用这一方法,需以长年积累起来的地价变动资料作为分析依据。地价的时间序列最好在ro年以上。因为时间序列愈长,愈能排除偶然因素和短期因素对趋势值的异常干扰。另外,用地价长期趋势图可比较两个地段地价_L涨的强弱程度,如果长期趋线越陡,则表明该地段地价升值性越强;反之,则表明该地价的升值性越弱。
