5. The emergence and development of virtual economy virtual economy is a new word in recent years, which has three categories. First, it refers to the trading activities of virtual capital such as securities, futures and options; Second, it refers to the economic activities (Virtual Economy) with information technology as the tool. Some people also call it digital economy or information economy; The third is the visual economy simulated by computer. There are some relations among these three categories. This paper mainly discusses the first category. The concept of virtual capital was first put forward by Marx. In the fifth chapter of the third volume of capital, as well as in the 25th chapter of credit and virtual capital, he made a detailed analysis of virtual capital. He believes that virtual capital is generated on the basis of loan capital (interest bearing capital) and bank credit system, including stocks, bonds, real estate mortgage, etc. Virtual capital itself does not have value, which is different from real capital, but it can generate profit (some form of surplus value) through circular movement, which is the same with real capital. Although more than 100 years later, with the development of the world economy, there are many new things (such as futures, options and various financial derivatives) and new situations (such as money departing from the gold standard, economic globalization, etc.), Marx's analysis of virtual capital still has important guiding significance in the current study of virtual economy. According to the author's personal understanding, the so-called virtual economy refers to the economic activities related to the circular movement of virtual capital mainly relying on the financial system, which is simply the activities of directly making money from money. Its earliest origin can be traced back to private business lending. For example, Party A urgently needs to buy some raw materials or goods, but he does not have enough funds, and Party B just has a sum of money idle, so Party A borrows a certain amount of money from Party B and promises to repay the principal and interest within a certain period of time. Through this activity, Party A obtains the right to use the money, which can be used as a means of payment to make profits through actual economic activities, while Party B maintains the ownership of the money and the right to recover the principal and interest from party a when e. At this time, the IOU in a certain B's hand is a kind of rudiment of virtual capital, which gains value through circulation of borrowing and repayment. At this time, Party B did not engage in actual economic activities, but made money through a virtual economic activity. Thus, the first stage of the development of virtual economy is the capitalization of idle money, that is, idle money in people's hands can be turned into capital that can generate interest. The second stage is the convergence of interest bearing capital, that is, the bank acts as an intermediary to borrow the idle money in people's hands and then lend it out to earn interest. People can also use the idle money in their hands to buy various securities to earn interest. At this time, the deposit certificates and securities in people's hands are also virtual capital. The meeting of interest bearing capital can lead the capital to be transferred from people who can't use it in proction, circulation and other actual economic activities to people who can use it in actual economic activities. It can also concentrate the capital scattered in people's hands to carry out large-scale economic activities, so as to improve the efficiency of capital use. The third stage of the development of virtual economy is the marketization of securities, that is, securities can be bought and sold freely according to their expected returns, resulting in financial markets (such as stock market, bond market, etc.) for virtual capital transactions. The marketization of marketable securities can guide the capital flow to instries with better expected returns, thus further improving the efficiency of capital use. In 1898, the futures trading mode of agricultural procts also appeared, and then graally extended to nonferrous metals, petroleum and other instrial raw materials, which is a new form of virtual capital. The fourth stage of the development of virtual economy is the internationalization of financial market, that is, virtual capital can be traded across countries. Although this process can be traced back to the mid-19th century when debtor countries and railway companies issued fixed rate bonds in the financial markets of Britain, France and Germany, there was relatively large-scale cross-border securities investment since the 1920s, and it was not until after the Second World War, under the promotion of the Bretton Woods Agreement and the general agreement on Tariffs and trade, Only then graally formed the scale huge international financial market. The internationalization of financial market can lead the capital flow to the instries with better income in the international scope, which can greatly improve the utilization efficiency of capital. At the same time, it also forms a new financial market foreign exchange market. Futures trading is becoming more and more virtual, which means buying futures as a means of speculation. Since the 1960s, futures trading has appeared in the trading of stocks, bonds, foreign exchange and other financial commodities, and options trading also appeared in 1973. The fifth stage of the development of virtual economy is the integration of international finance, that is, the relationship between domestic financial markets and international financial markets is closer, and the mutual influence is also increasing. With the formation of floating exchange rate system, the enhancement of financial innovation, the rapid progress of information technology, the increase of financial liberalization, and the development of economic globalization, the flow of virtual capital in the financial market is faster and faster, and the flow is also larger and larger, which makes the scale of virtual economy increasing. It is reported that since the 1980s, the average annual growth rate of the world economy and international trade has been around 3% and 5%, respectively. However, the international capital flow has increased by 25% and the total price of global stocks has increased by 250%. In 1997, the total amount of virtual economy in the world reached 140 trillion US dollars, which is about four times of the total GDP of all countries in the world (28.2 trillion US dollars). The average daily flow of virtual capital in the world has reached more than US $1.5 trillion, which is about 50 times of the world's average daily real trade volume. It can be predicted that with the development of e-commerce and e-money, the scale of virtual economy will expand. According to the viewpoint of system science, the characteristics of virtual economy system can be regarded as a system, so the characteristics of the system can be investigated from the internal structure of the system and the interaction between the system and the environment, so as to reveal the law of system evolution. The author thinks that the virtual economic system has the following main characteristics. 1. Complexity: the general characteristics of complex system are large scale, high coupling, low transparency, dynamic and open, but its most essential characteristic is that its components have a certain degree of intelligence, that is, the ability to understand its environment, predict its changes, and take actions according to the predetermined goals. This is the internal reason for biological evolution, technological innovation, economic development and progress. Virtual economic system is a complex system, its main components are natural persons and legal persons (investors, investors, and financial intermediaries). They carry out virtual economic activities in the financial market according to certain rules. Although everyone has the freedom to make decisions independently in accordance with his own understanding of the environment and its development prospects, as well as his predetermined goals, everyone's decisions can not but be affected by the decisions of others. Although the system is prone to chaos e to the nonlinear interaction between components, it can show a certain order and stability e to the self-organization of the system. 2. Metastability: metastable system is a system which is far away from equilibrium, but can maintain relative stability through the exchange of material and energy with the outside world. It is called a system with dissipative structure in system science. Although the system can achieve stability through self-organization, its stability is easily destroyed by external small disturbance. When the stability of the system is destroyed, it may move in a certain range and enter the state of stability and motion alternately. From the macroscopic point of view, it can be considered that the system is stable in a certain range, that is, it has regional stability. But sometimes the system may change dramatically after instability, and even cause the system to collapse. After the system collapses, it may return to the metastable state through deep structural adjustment, or it may die out. Generally speaking, the greater the inertia of the system, the less likely it is to collapse. The virtual economic system is a kind of metastable system, which must rely on the exchange of funds with the outside world to maintain relative stability. There are many reasons for its metastability, but the most fundamental reason is the inherent instability of virtual capital. The inherent instability of virtual capital comes from its own virtuality. For example, the securities itself does not have real value, but represents the right to obtain income. It is a kind of ownership certificate, which makes the holder legally have the right to claim the part of the resial value that should be obtained by the capital he paid when purchasing the securities. When the securities can be traded in the securities market, because it has no value, its price is determined not according to the objective law of value, but according to people's subjective prediction of its future price, and also affected by its supply and demand, which makes its price more divorced from the actual economic activities. When the price of virtual capital is far away from its reasonable expectation, it will form & quot; Economic bubble " It depends on the continuous injection of funds from the outside world to maintain its stability, but this is only a kind of false and easily broken stability. The instability of virtual capital also comes from the virtualization of money, that is, money does not really have value. Since the decoupling of currency from gold standard and gold exchange standard, although it still has the use value as a means of payment, it no longer has the real value that can be measured by some kind of material object. At this time, the value of money can only be measured by its purchasing power, and the purchasing power of money is also affected by currency circulation, interest rate, exchange rate, people's consumption behavior and other factors, so the virtualization of money will enhance the instability of virtual economy. The instability of virtual capital also comes from the positive feedback in the virtual economic system. For example, the more people buy a certain stock, the more people will be prompted to buy it. This kind of interaction between people is positive feedback, which will cause amplification effect and make the price of virtual capital fluctuate greatly. 3. High risk: in economic activities, the so-called risk refers to the difference between people's expected income and actual income, which comes from the uncertainty of the objective world and the limitation of people's ability to understand the objective world. The fictitious economy has the possibility of bringing high income as well as high risk. The high risk of virtual economy system comes from its complexity and metastability. Firstly, the inherent instability of virtual capital leads to its price volatility, and the increase of financial market transaction scale and variety makes it more complex; Secondly, people's ability to predict the market and environmental changes is insufficient, and they have not found a good method to predict the expected return so far, which is easy to lead to mistakes in decision-making; Thirdly, many people have limited ability to bear risks, so they are at a loss when facing huge risks, and even magnify the risks e to positive feedback; In the end, a lot of people are chasing after each other
