In 1979, land prices fluctuated wildly, land speculation was rampant, and there were calls to "let the assessed value approach the market value." In 1987, land once again shot upward, and the government again revised assessed values upward a great deal. This was especially the case in Taoyuan, site of much infrastructure construction: This year assessed values went up almost 50 %.
民國六十八年地價巨幅波動、土地炒作成風，社會上就有「讓公告現值接近市價」的呼籲；七十六年土地又開始另一波飆漲，政府也跟著大幅調漲公告現值；尤其在重大公共建設如北二高經過的桃園，今年公告現值幾乎調整了百分之五十。
