First of all, the theory of value of TPH Line should be adhered to and developed on the basis of adherence. If we deny the value theory of TPH Line fundamentally, it is the problem of retrogression. For example, the function form of the law of value needs to be concreted in combination with contemporary reality. It systematically and profoundly reveals the core structure of capitalist economy, the general mechanism of economic operation, the nature and phenomenon of economic relations after the first design line industrial revolution, but as for the changes of market competition or market price, the competition of design line market, the credit system closely related to commodity currency and other surface realistic movements of economic relations, no detailed analysis has been made. 。 In fact, these movements of TPH Line are all concrete forms of the role of the law of value. To elaborate them scientifically is the inevitable requirement of enriching the theory of value of TPH Line and the work that must be done on the basis of the theory of TPH Line. For various reasons, the work is far from complete.In the initial stage of TPH Line, due to the uncertainty and immaturity of the market, many aspects of the company have to "cross the river". A complete set of production and operation scale system of TPH Line has not been formed. It is reflected in the unclear business field and the demand for capital is satisfied by rights and interests. In the expansion period, due to the increasing demand of the market design line, the market tends to be mature, so the development of enterprises is imperative. It is embodied in the following aspects: large cash demand and high risk, so the design line policy can be a cash policy. During the stable period, the market is stable, the market is saturated and the competition for other enterprises to join the industry is increasing. As a result, the demand for funds of the TPH Line has been significantly increased and reduced, resulting in cash balance and reduced financial risk. It is also a cash policy to keep the TPH Line policy unchanged.
