First, seeking profit-what is an enterprise driven by the internal factors of enterprise economic behavior? Why do enterprises exist? This is the logical premise of studying all economic behaviors of enterprises. According to modern enterprise theory, there are two different definitions of what an enterprise is. One is the definition of Coase. He believes that "the distinctive symbol of an enterprise is a substitute for the price mechanism". "Outside the enterprise, the price movement regulates production, and the coordination of production is achieved through a series of market transactions. Within the enterprise, these market transactions no longer exist, and the complex market structure related to these transactions gives way to the entrepreneur coordinator who regulates production. In other words, the enterprise is a means and mechanism to coordinate production that can replace the market mechanism. The second is the definition of Zhan Sen and McLean. They think that enterprise is an organization that acts as a connection point for "a set of contractual relations" between individuals, and it is a kind of legal fiction. As far as enterprises are concerned, this "contractual relationship" is the contractual relationship between labor owners, providers of material and capital inputs, and consumers who produce products. Looking at the two definitions, we might as well make the following preliminary interpretation of the enterprise: the so-called enterprise refers to an individual cooperative organization that can coordinate the contractual relationship between internal members and stakeholders and replace the market mechanism. Since enterprises are individual cooperative organizations, why do individual small producers who can spontaneously adjust their mutual interests by relying on market mechanisms cooperate to organize enterprises? In this respect, Marx's social forces are essentially different. " Compared with the sum of the same number of individual work purposes, combined with working days, it can produce more use value, thus reducing the labor time necessary to produce certain effects. "Unlike Marx, modern western economists analyze the causes of enterprises from the perspective of combining production costs with measurement costs. For example, the famous American economists Aqin and Demsetz once pointed out in an article: "If the output produced by the cooperative group is large enough to offset the cost of organizing and restraining the members of the cooperative group compared with the total output of inseparable production, the cooperative group will be used for production. On the other hand, western economists discuss the formation of enterprises from the perspective of transaction cost. For example, Williamson believes that "environmental uncertainty and the relationship between a few participants in the transaction are environmental factors that lead to market failure, coupled with human factors of bounded rationality and opportunism, people will pay a huge price when formulating, fulfilling and executing market contracts, which will eventually lead to transactions within enterprises rather than in the market, so replacing market transactions with enterprise organizations is conducive to saving transaction costs. From the above analysis, we can draw the following logical inferences: No matter Marx's analysis of the causes of classical enterprises or modern western economists' exposition of the formation of modern enterprises, one thing is the same, that is, enterprises, as individual cooperative organizations, are produced in order to save production costs and measure costs, reduce transaction costs, improve production efficiency, and create economies of scale by means of "team production", thus realizing production and business activities that individuals cannot engage in.

Second, seeking morality-external adjustment of enterprise economic behavior Since enterprises exist because of "seeking profit", how can they seek profit? How can we benefit in many ways and for a long time in order to maintain our own survival and development? In other words, in what ways and through what channels can enterprises maximize their own interests and utility and improve long-term welfare? First of all, the realization conditions for enterprises to seek profits depend on whether there are things that benefit others. We know that under the market economy, enterprises are engaged in the production of goods and the provision of services, not to meet their own needs, but to exchange, and to achieve their own profit pursuit by meeting their own exchange needs. To achieve this goal, enterprises must have two conditions: first, they must be able to produce a certain number of products or provide a certain number of labor; Second, the products or services they produce must be useful to others and can satisfy others. If an enterprise can neither produce a certain number of products nor provide a certain number of services, but only wants to get something from other economic entities, then in a freely exchanged market, other economic entities have legitimate reasons not to contact them-first of all, because every enterprise will pursue and protect its due interests. Enterprises come first, because enterprises exist in society, and the normal operation of their profit-making activities depends on the recognition and protection of society. According to the theory of modern property rights economics, "the essence of market exchange is the exchange of a group of rights". In order to make the price mechanism work, the participants in the transaction must have clear, exclusive and freely transferable property rights to the goods to be exchanged. Without independent property rights, enterprises allowed to enter the exchange market cannot have independent status, and it is impossible to truly become an independent, self-financing, self-restraint, self-developing economic entity and competition subject. If enterprises want to obtain independent property rights of their products for exchange, it depends not only on whether they have worked hard to produce these products, but also on the recognition and guarantee of product ownership by society. If there is no system in society to recognize and guarantee the legitimate pursuit of enterprises' own interests and the ownership of such interests, then even if enterprises have paid great efforts to produce a certain product, they cannot guarantee that they have absolute property rights and continue to make profits. Second, because the profit-seeking activities of enterprises will have external effects, the smooth progress of their profit-seeking activities needs to rely on the strong regulation of social forces. The so-called external effect, according to the explanation of North, a representative figure of western new institutional economics, is that "when the personal cost caused by someone's behavior is not equal to the social cost and the personal benefit is not equal to the social benefit, there is externality", that is to say, the influence of an economic activity is not necessarily reflected in its own cost or benefit, but it will bring benefits or disadvantages to other economic entities and even the whole society.
