Although an enterprise's internal trade fair eliminates or reduces some of the market transaction costs, it also brings with it the specific transaction costs of the enterprise. The main reason for this defect is also the incompleteness of information. Specifically, first, there are various contractual relationships among enterprises, including contractual relationship between enterprises and workers, contractual relationship between enterprises and managers, etc. The enterprise should supervise the work of the workers and products that it employs, as well as the managers and other personnel, and induces them to work hard for the enterprise. So, companies are signing contracts and spending on oversight and incentives. Secondly, on the one hand, corporate decision makers often need to obtain information from subordinates. On the other hand, the decision-making information of the upper level of the enterprise should be realized by passing it to the subordinate. The information transmission of these two different directions will be distorted by the increase of subordination of enterprise scale, resulting in the loss of enterprise efficiency. Once again, the subordinate of the enterprise often conceals or passes the wrong information to the superior for selfish motives, so that the superior can make decisions that benefit the subordinate. Or, the subordinate's decision to the superior only passes or executes the part that is advantageous to oneself. These will result in the loss of enterprise efficiency. Thus, the expansion of enterprises is limited. According to coase's theory, the scale of the enterprise should be expanded to this point, that is at this point to increase the cost of an internal exchange cost equals the cost through the market exchange cost and so on. The essence of economic value is human labor in the process of human economic products and relations. The value of the use value of creating products and the labor value of creating production relationship. The value concept in "das kapital" refers to exchange value, which is the essence of capital relations. Can't be replaced by local value The market can indeed be described as a laissez-faire pricing mechanism. However, this price mechanism does not operate in a vacuum, and does not work effectively in any social system. The basic premise of the efficient operation of the price mechanism is the implicit assumption of Smith: to recognize individual "lusts" and to clear and protect individual property rights. Clear and guaranteed personal property is the basic premise of market existence. It is necessary to recognize the personal "lusts" and to ensure that individual property rights are supported by the corresponding institutions, which are not in our society. But to increase political accountability and to sacrifice the independence of the central bank is to throw the baby out of the bath. Monetary policy is complex and technical. Handing control to politicians is more prudent than handing over keys to the country's nuclear power plants. Although miolo is doing well in China, tiloni also talks about his worries. He believed that the greatest advantage of the Brazilian wine is cost-effective, but compared with wine importing "zero tariff" neighboring Chile, Brazil wines in the Chinese market at present stage, there is no big advantage to speak of. "Our biggest problem right now is the price," he said. "our wine is very competitive when it comes out of the factory." But Chile and China have zero tariff agreements on wine trade, and we don't, which makes our products much more expensive in China. However, I believe that this problem will be solved and the demand for wine in the Chinese market is very high. I believe that the future development of Brazilian wine in China should be good.
