中文摘要：

法定财富标志在货币形态从“真金白银”到“大象无形”的演化过程中消失。信用货币时代，货币发行量由中央银行根据物价稳定、经济增长、充分就业等货币政策最终目标来决定，并不以任何法定财富标志为支撑。1990年日本泡沫经济和2008年美国次贷危机的演绎结果表明，正是上述最终目标的内在矛盾性和基于此的宏观调控政策导致经济在萧条与过热之间循环。在广义虚拟经济时代，法定财富标志实乃社会经济的定海神针。我国可考虑将公租房确定为法定财富标志之一，通过合理运作，一可满足客观存在的投资需求、抑制房地产泡沫；二可促成居者有其屋的实现；三可使中央银行对货币的调控更加科学。而全面解决财富标志缺失的问题，则是从根本上破解所谓“经济周期”的必由之路。

英文摘要：

supply is targeting the final goals of monetary policy, such as, stable price, economic growth and full employment, not influenced by any fiat wealth identifications. After analysis of 1990 bubble economy of Japan and 2008 subprime crisis of USA, this paper analyzes the inherent contradictions of the final goals of monetary policies and the fluctuations of economy from depression to over-heat due to the macro-economy policies. Finally, based on four principles of choosing fiat wealth identifications, it is suggested that public rental houses should be considered to be fiat wealth identifications, while the housing demands and investment demands can be divided, and public rental housing exchange market should be established, and central bank can increase or soak up liquidities through buying or selling public rental houses.
