两个市场均衡的价格与产出弹性的理论分析

摘要

According to the common equilibrium theory of two markets and Cobb-Douglas model,output and price function of product and monetary markets were applied respectively,and the relation between price level and output was discussed by means of elasticity theory. The analysis showed,at product markets,price and output were related directly in short period,and if the increase of disposable personal income could not keep pace with output growth and the rising of price would reduce economic growth rate in long period. At the monetary market,if output growth could increase the interest rate and price level was promoted,on the other hand,if macro-control targets focused on increasing total demand and reducing the interest rate,and economic growth would decrease prices level and curb inflation.%基于两个市场的一般均衡理论，运用柯布道格拉斯生产函数形式在产品市场建立国民收入决定函数，在货币市场建立价格函数，进一步通过弹性研究价格水平与产出的关系。通过分析，产品市场上，短期内价格与产出同方向变化，长期时若居民个人可支配收入的增加跟不上价格水平的上涨，则价格的提高会降低产出增长率；货币市场上，若产出的增加引起利率水平的上升，则会引起价格水平的上涨，若采取控制利率水平的政策，产出的增加则会抑制价格上涨，从而起到降低通胀的作用。
