得到主要結論如下:當橫向並購產生優勢企業時,原先市場的領導層企業數目不等於零時,橫向並購動機存在,而且在一定條件下,這種橫向並購會使社會福利增加,這正是橫向並購得到支持的原因所在;當橫向並購不產生上優勢企業時,動機存在的條件極為苛刻,基本上與不產生優勢企業的假設相違背,可以認為這種並購的動機不存在,而且這種並購導致產品價格上升,社會總福利降低;如果市場近似古諾競爭市場,並購后並購方生產能力不能滿足理論上的最優產量,只要其生產能力超過並購前參與並購各方的最優產量之和,那麼並購動機就會存在,而且橫向並購會導致產品價格下降,社會總福利上升;當處于高層次的企業並購低層次企業時,由於並購者不能獲利或者未參與並購者獲利增加比並購方多,並購動機不存在或者很微弱。Our factory has accumulated abundant practical experience through the untiring efforts for many years, always with " loyal to cooperate in, mutual benefit and reciprocity, high - quality practical, the price is rational " as the aim, insist that the brand was developed, market - oriented, have gained the good style of work in the field of business with the sincere cooperative attitude, favor by the masses of customers and approval, according to " quality seek survival ", in order to " prestige wins the customer ", welcome with open arms chinese and foreign travelling trader, come kind come electric machining customize the products of various kinds, " quality is the life ", our factory offer most high quality products and service to you, welcome all kinds of product the above come kind have made to order
