當前的經濟活動中，經營者從謀求最大化經濟效益的角度出發，以具有獨立經濟價值的權利為抵押物設定抵押的情形並不鮮見，但因為法律對該類權利抵押並未加以明確的、列舉式的規定，法院多將其認定為無效，從而使正當權益得不到應有的保護，使正常的經濟活動受到不合理的束縛，使作為最完善、最典型的擔保形式的抵押不能充分發揮其應有的作用。The payments for capital and labor are totally set by market power and capital ( labor ) suppliers of any firm have no power to alter the transaction terms with its labor ( capital ) suppliers to their advantage and thus every firm generate zero economic profit. every firm ' s value is equal to the sum of the market prices of the human assets and physical assets that it use and thus the formation and disbandment of a firm have no influence on the interest of any of its members. through an efficient comparison of production within the firm and the scattered individual production coordinated through markets, the dissertation reveals that the origin of the power relationship phenomenon within the firm is that the suppliers of the resources to the firm in real world are unable to enter into legally binding complete contracts as walras assumed
在一般均衡範式中，企業是一個追求利潤最大化的原子；企業的生產過程被描述為一個「黑箱」 ，它自動地、無摩擦地把任何一組投入轉化為既定的技術約束下所能生產的最高產出；資本和勞動僅僅是生產過程中不同類別的投入，它們之間的關系是對稱的，它們各自的報酬都是完全由市場整體的力量決定的，任何一個企業的資本（勞動）提供者都不可能為了增進其自身的利益而改變與勞動（資本）提供者的交易條件，從而任何一個企業產生的經濟利潤都為零；任何一個企業的價值都等於該企業使用的人力資產和非人力資產的市場價格之和，組成一個企業不會增進任何參與人的收益，解散一個企業也不會降低任何參與人的收益。Under the budget of the survival ability, reducing survival and breeding cost will be the economic selection for varied forms of animal marriage
