画个edgeworth box 便可以得到答案了 K____________________Y物 | | | | | | | | | | | | l__________________| X物 L 上面这个箱型图 左下角和右上角画一条对角线 根据题目设定，契约线会在对角线之右方呈现弓形 (请原谅我不会用BBS画图QQ) 因此当X物生产产量增加，Y物产量减少，且仍符合生产效率时 (K/L) of X 增加，且(K/L) of Y也增加 (看斜率便可以直观判断了) 大概是这样，如果讲得不详尽或有错误还请各位高手指教~ : Suppose two goods (X and Y) are being produced efficiently and that the : production of X is always more labor intensive than prodction of Y. : Production depends on two factors (capital and labor); these may be : smoothly substituded for each other. The total quantities of these : inputs are fixed. An increase in the production of X and a decrease : in the production of Y will : A) increase the capital-labor ratio in each firm : B) decrease the capital-labor ratio in each firm : 答案为A : 我的想法: : 为什麽不是B呢? 增加生产劳动密集的X，使生产可能线上的生产均衡点下移， : 同时资本劳动比例(K/L)下降，请问答案错了吗? 还是我想错了呢? --
