1.引言(Introduction) 1.1局部均衡( Partial Equilibrium)与一般均衡(General Equilibrium) 一、局部均衡(Partial Equilibrium) 只考虑一个市场(single market)的情况(假设其他市场不变),对部门j 而言,当对该部们的产品x,的需求x(p)与该产品的供给x(p)相等时,即 x(p,)=x(p)时,这个市场就达到了均衡; 这种单个市场达到的均衡状态称为“局部均衡”(Partial Equi librium 那么是不是所有的市场能同时达到均衡呢?这就涉及到“一般均衡”(General Equilibrium)的概念了
