北宋中后期四川铁钱币值和流通地区的变化

Change of Currency Value and Circulation Area of Sichuan Iron Coin in Mid and Late Bei Song

北宋中后期四川铁钱币值的变化 ,主要受到两个因素的影响 :即铁钱成为交子的准备金及陕西地区铸造铁钱的冲击。由于交子发行额度的变化以及陕西铁钱的不断贬值 ,四川铁钱的币值不断波动 ,宋政府采用暂停铸造铁钱、禁止陕西铁钱进入四川流通以及稳定交子发行数额的措施 ,使四川铁钱的币值在北宋中后期仍然基本得到稳定。

The currency value change of Sichuan iron coin in the mid and late Bei Song is affected by two factors: iron coin becoming the reserve fund of paper currency 'jiao zi', and the impact of Shanxi's iron coinage. It constantly fluctuates because of the issuing amount change of jiao zi and constant devaluation of Shanxi iron coin. The Song government basically stablizes it by suspending iron coinage, fobidding Shanxi iron coin's circulation in Sichuan, and stablizing the issuing amount of jiao zi.
