difference between accounting profit and economic profit pdf All things in the world are constantly moving. In all attributes of matter, motion is the most basic attribute, and other attributes are specific manifestations of motion attributes. For example, spatial attribute is the broad embodiment of physical activity. Time attribute is the persistence of material movement. Material movement form is varied, for each specific material movement form the corresponding form of energy, such as: and macro mechanical movement of the object corresponding to the form of energy is kinetic energy; The energy form corresponding to the molecular motion is heat energy; The energy form corresponding to the atomic motion is chemical energy; The energy form corresponding to the directional motion of charged particles is electric energy; The energy form corresponding to the photon motion is light energy; And so on. The motion characteristics of two objects can be described and compared by some physical quantity or chemical quantity. For example, two objects that make mechanical motions can be described and compared by physical quantities such as speed, acceleration and momentum. The current can be described and compared with current strength, voltage, power and so on. , but when the movement form phase at the same time, not two material movement characteristics only can describe and compare each other quantities is energy, the energy feature is moving all the common characteristics of material, energy scale is measure all movement in the form of a general. Thus, a new philosophical definition of energy can be made. Today, because all of these reasons, the central bank hit: lost the inflation target, failure to maintain financial stability, not transparent to restore stability, without fully considering the global impact of policy. Politicians are unhappy with their performances and are seeking to regain control. Because economists understand earnings as actual material wealth increase, accounting experts think the output value of more than the difference between the input value is profits, there is a contradiction and two kinds of income concept. The specific performance is: The fund said last year that it would grow 1.1% in 2017 and then increase its forecast to 2%. But in the wake of the global financial crisis, the risks of monetary and fiscal policy have been highlighted and central Banks have been given additional responsibilities. Deciding whether or not to rescue a particular financial institution, whether it guarantees system stability or other reasons, has obvious consequences for individual investors.
