Meanwhile, from the angle of system change, it is proved that the change of factors centering on productive forces, causes the existence of the external profit, which is not available under household responsibility system, thus leading to the need for a new system. this shows that the balance of the previous farmland property rights system has been broken, and there is necessity and inevitability to innovate and perfect the current farmland, property rights. moreover, the reduction of system innovation cost and the increase of anticipated profit add to t
從制度變遷的角度論證了：由於以生產力為中心的諸項因素發生了變化，導致了家庭承包制下無法取得的「外部利潤」的客觀存在，從而引致了新的制度需求，說明了農地產權制度的原有均衡已被打破，對現行農地產權制度進行創新完善具有了必要性和客觀必然性；而由於制度創新的成本下降、預期收益提高 -
