2、求變動(dòng)和供給變動(dòng)對(duì)均衡價(jià)格和均衡數(shù)量的影響.解答:(1)將需求函數(shù)Qd=50-5P和供給函數(shù)Qs=-10+5P代入均衡條件,有:50-5P=-10+5P得:Pe=6以均衡價(jià)格Pe=6代入需求函數(shù)Qd=50-5p,得:Qe=50-5*6=20或者,以均衡價(jià)格Pe=6代入供給函數(shù)Qs=-10+5P,得:personalcreditbusinessprocessmanagement,anddevelopmentofbusinessprocesses,cleartheloanobjectandscope,establishloanoperation
