人民幣升值問題

可以按照楼上之算法，如果人民币真系咁样升，好多国家都有严重问题出现；
1/。中国---对美国之大部份出口基本上會消失，中国嘅工厂面临大规模的倒闭，工人失业會形成社会动荡不安。什么暴乱都有可能发生。美国之农产品也会大量的卖到中国，中国的农产品变得没有销路，农民也没有饭吃导致更严重的动乱。
2/。香港---猪肉从1千多港币一担升到6千多港币一担，菜心从HKD8一斤变成HKD32一斤。。。估计将会有超过100万人上街，然后也发生暴乱。。。
3/。美国---虽然农产品可以大量输出到中国，但其他消费品原来大部份在大陆生产的都大幅度涨价，以致美国也被输入性的通货膨胀所影响。到时候美国也暴乱（最近现实生活中都快有暴乱了）。
总结：全世界都受到拖累，齐齐暴乱，甚至战争！

港幣 and 美元 有聯繫匯率.
$1美元 = 大約$7.78港幣
Since there is 聯繫匯率, this rate does not change.

If 人民幣升值4倍, it means
$1美元 = $1.6人民幣
$1人民幣 = $4.8港幣...

Well... HK has to buy so many primary product from mainland China using 人民幣. If 人民幣 rises 4 times, it will mean every thing in HK will cost like 4 times as much. The world will be crazy.

聯繫匯率 is controlled by the HK government. If USD has to drop this much, I don't think HK will want to continue the 聯繫匯率 without change. Also, it is impossible for the rate to change like 4 times in short period. If it is over a period of 30 years, you may not feel much. If it is an overnight change, both US and China will both in huge trouble.

US wants 人民幣 to rise, so US product can be cheaper in China. But it won't be possible for 人民幣 to rise for 4 times in short term.
