影响一国贸易条件的因素很多。除了熟知的供求层面因素外,货币及宏观经济运行特点等因素也可能引发价格贸易条件的长短期效应。运用新开放宏观一般均衡模型发现:(1)“货币的投放速度”可能引发一国价格贸易条件的短期波动,但不会影响长期价格贸易条件。而“货币供给的波动性”能够对一国长期价格贸易条件产生实质性影响,且跨期替代弹性的大小对传导程度和方向的作用不可忽视。(2)当外国的货币供给波动性加剧时,本国的长期贸易条件将得到改善。只是针对不同跨期替代弹性的经济体,其改善的程度有显著不同。(3)工资粘性不仅影响一国价格贸易条件的波动幅度,还影响调整周期的长短。一国的价格运行机制越接近弹性化,在面临货币冲击时,其价格贸易条件的波动幅度越小,完成动态调整所需的时间越短,表现出较强的抗冲击能力。
影響一國貿易條件的因素很多。除瞭熟知的供求層麵因素外,貨幣及宏觀經濟運行特點等因素也可能引髮價格貿易條件的長短期效應。運用新開放宏觀一般均衡模型髮現:(1)“貨幣的投放速度”可能引髮一國價格貿易條件的短期波動,但不會影響長期價格貿易條件。而“貨幣供給的波動性”能夠對一國長期價格貿易條件產生實質性影響,且跨期替代彈性的大小對傳導程度和方嚮的作用不可忽視。(2)噹外國的貨幣供給波動性加劇時,本國的長期貿易條件將得到改善。隻是針對不同跨期替代彈性的經濟體,其改善的程度有顯著不同。(3)工資粘性不僅影響一國價格貿易條件的波動幅度,還影響調整週期的長短。一國的價格運行機製越接近彈性化,在麵臨貨幣遲擊時,其價格貿易條件的波動幅度越小,完成動態調整所需的時間越短,錶現齣較彊的抗遲擊能力。

There are many factors that affect a country' s terms of trade( TOT). In addition to the familiarly known factors from supply side and demand side, macroeconomic environment and operation features may also trigger the adjustments for price terms of trade in the short and long run. Applying the dynamic stochastic general equilibrium model, we found that: ( 1 ) the speed of money supply may cause short-term fluctuations for TOT, but does not have influence on TOT in the longterm. The volatility of money supply does have substantial impacts on TOT in the long-term and the role of inter-temporal elasticity of substitution is important. (2) when the volatility of foreign money supply increases, the country' s long-term TOT will be improved with different degree due to inter-temporal elasticity of substitution. (3) wage stickiness not only affects the fluctuation extent for TOT, but also affects the adjustment cycle length. In the face of monetary shocks, the closer to flexibility for price adjustment mechanism, the smaller the fluctuation extent for TOT and the shorter the complete dynamic adjustment cycle. Elastic price mechanism is conducive to a country' s TOT stability.
