An overview of the advantages of virtual currency combined with

1. Some time ago, virtual currency was affected by various factors, showing the phenomenon of price instability, so now many investors in the face of virtual currency are beginning to follow their own cautious mood, action is also very prudent. Even if this delays the expansion progress of virtual currency, in terms of long-term strategy, it can effectively promote fair competition in the virtual currency world, and the rising momentum of blockchain virtual currency is likely to be fully released this year. In the long run, the regions with the most potential and the fastest growth in the world economy will still be concentrated in the Asia Pacific region. This year's development potential is bound to be sufficient and the economic growth is bound to be considerable

2. Joint proction refers to the process in which different procts are proced together in the same enterprise because of their dependence on raw materials< CO proction is originally a concept of natural science, which describes an inevitable phenomenon in the process of chemical transformation and separation. The combination of joint proction and economics began with the concept of joint proct. When Steeman analyzes the proction of joint procts, the process of procing not only one proct but two or more procts is called joint proction. Shi Lei brings the concept of system into joint proction, and believes that a certain investment quality can not only process a certain amount of final procts, but also "process" the corresponding system, which mainly refers to the structure of economic proction. In the theory of public goods, the combination of public and private proction factors is called joint proction. From the point of view of thermodynamics, all proction is joint proction. Joint proction is common in economy and ecosystem. Human economic activities proce two kinds of procts, one is expected proct, and the other is undesirable waste. In proction theory, when different proct combinations are proced under the same proction input and the two procts or proct combinations are technically interdependent, it is called joint proction. In the theory of enterprise management, the problem of cooperative proction in advance and joint participation in distribution afterwards by different economic entities is also understood as a kind of joint proction, which includes two stages of distribution. Ji Yalan's definition of joint proction is probably the most comprehensive. He thinks that joint proction means that the same factor input can proce a variety of procts at the same time. Joint proction includes technical union, economic union and institutional Union< The concept of joint proction has been widely used and developed in public economics, enterprise management, agricultural economics, ecological economics and other fields< Joint proction and public economics < br > arrow and Debreu pointed out that under the condition of joint proction, whether it is good or bad, as long as the indivial proction set is convex and the possibility of free domination is fixed, there is a general equilibrium. Zheng Yisheng pointed out in the theory of public goods that expanding the scope of "public property resources" includes not only natural resources, but also "social" resources. The existence of public property resources and "quasi public property resources" in developing countries should not be ignored. It is necessary to pay for the social cost of public resources< Br > 2. Joint proction and enterprise management < br > the theory of joint proction has also been widely developed in enterprise management. Computer based models and methods have been developed to solve problems related to planning and joint proction cost allocation. From the point of view of the company in the theory of joint proction, the distribution of costs among joint procts is basically arbitrary. In the literature of general equilibrium theory, there is no in-depth study on the economic attributes with the characteristics of joint proction, and its focus is on the existence and maximization of general equilibrium under general assumptions. Ralph Winkler focuses on the choice between new consumption and proction caused by new technology and natural deterioration, and tests whether and to what extent the necessary and sufficient conditions for process innovation are effective in the presence of possible harmful output< Br > 3. Joint proction and ecological economics < br > it is worth noting that the theory of joint proction graally infiltrates into the field of ecological economics and agricultural economics, and has been developed to a certain extent< Br > the nature of the alliance includes technological alliance, biological alliance, economic alliance and institutional alliance, which is the combination of economic goods and non economic goods. O'Connor and perrings pointed out that e to the limited absorption capacity of the natural environment to these pollutants (combined procts), it is difficult to have a stable growth path. The ecological allocation effect of joint procts is also being valued. Gao Jianzhong analyzed the proction of forest procts, and thought that forest cultivation is a common and joint proction process of multiple procts. The most common joint proction among multiple procts is the existence of variable proportion. The fixed proportion of joint proction is rare, it is only a special case of variable proportion of joint proction. Nalle et al. Applied the theory of joint proction to analyze the relationship between wood proction and wildlife protection, and put forward the countermeasures to solve the conflict between market-oriented commodity and natural system, as well as the path of sustainable development of economy and ecosystem. Freshwater et al. Analyzed the close relationship between commodity output and non commodity output from the development process, type and proction function of joint proction theory; Miettinen used the case of "Finnish wheat planting and wild quail chicken" to analyze the joint proction, which once again confirmed that agricultural proction has environmental and social functions in addition to economic functions< The following scholars have made important contributions to the study of major practical issues such as returning farmland to forest< When studying joint proction and private provision of public goods, Vicary strictly distinguishes the concepts of "contribution" and "donation", that is, people's provision of public goods is mainly realized by objective "contribution" and subjective "donation", and introces the concepts of "virtual price" and joint parameters, through the discussion of the existence of general equilibrium, It is pointed out that the provision of public goods can be realized by private provision, as long as the degree of Union and the threshold of "virtual price" are appropriate. This means that as long as there is a suitable degree of Union and reasonable compensation, farmers can willingly provide "ecological procts"< Ji Yalan pointed out that agricultural proction is a typical joint proction with multiple functions. Most of the agricultural procts have the nature of public goods or quasi public goods, while most of the agricultural procts are unique, and there is no non-agricultural supply channel; It is precisely because agriculture is the joint proction of economic procts and non economic procts, private procts and public procts, as well as the multi-functional proction of agriculture, that it is difficult to construct the proction function of a single proct. Even if an approximate joint proction function can be constructed, it is still difficult to avoid the neglect of non economic procts and (quasi) public procts; Although the market is ineffective for most agricultural procts, the market is the only source for farmers to obtain agricultural income, and it is difficult to get compensation for the contribution of the whole externality proced by the combined procts of agricultural proction to the society. Ji Yalan also studied the multi-function of agriculture, clearly pointed out that the core problem of joint proction is whether economic procts and non economic procts can be separated depends on the degree of joint proction, which determines who can provide the most effective non economic procts. Under the condition of joint proction, if the society is willing to pay for non economic goods, the market equilibrium result is not the best one.

The most important proction factors are ( labor, land and capital )

" factors of proction " is a basic category in economics, including human factors, material factors and their combination. Proction factors refer to all kinds of social resources needed for social proction and operation activities, and are the basic factors that must be possessed in the process of maintaining the operation of national economy and the proction and operation of market entities< proction factors include labor, land, capital and information

4. The demand of proction factors is a kind of derived demand, inced demand and combined demand

proction factors refer to all kinds of social resources needed for social proction and operation activities, and are the basic factors that must be possessed in the process of maintaining the operation of the national economy and the proction and operation of market entities
factor of proction is a basic category in economics. According to modern western economics, proction factors include labor force, land, capital and entrepreneur ability. With the development of science and technology and the establishment of intellectual property system, technology and information are put into proction as relatively independent factors. These proction factors are exchanged in the market to form various price systems of proction factors. The demand of proction factors is the direct embodiment of economic life

the influencing factors of the demand for proction factors:
1. The market demand for procts and the price of procts
2. Proction technology
3. The price of proction factors
4. Marginal proctivity refers to the increase in output per unit of proction factor input under other conditions.

5. With the accelerating process of globalization, as well as the continuous promotion of China's reform and opening up and the continuous optimization of instrial structure, the competitiveness of China's multinational companies is constantly enhanced. The integration of the world economy and the progress of modern science and technology have greatly reced the market transaction costs and provided a good external environment for the foreign direct investment (FDI) of China's multinational companies. All kinds of factors at home and abroad stimulate the rapid growth of China's FDI. However, e to subjective and objective reasons, the development of China's multinational companies is relatively backward, the location distribution of China's FDI is too concentrated in some countries or regions, the overall investment efficiency is low, and even causes serious loss of capital. Therefore, how to optimize the location distribution of FDI and improve the efficiency of FDI investment has become an urgent task. Based on the characteristics of location distribution of FDI of China's multinational corporations, this paper deeply analyzes the main problems of location selection of FDI of China's multinational corporations, and puts forward countermeasures and suggestions to optimize the location distribution of FDI of China's multinational corporations and improve the investment efficiency based on the main influencing factors such as domestic and foreign environment, investment subject, instrial structure, domestic and foreign regional advantages. Firstly, this paper makes an empirical analysis on the investment behavior of Chinese multinational corporations from the perspective of FDI location distribution. On the whole, an important feature of FDI of China's multinational corporations is that there is too much false investment and less real investment. The instrial structure of FDI also deviates from China's real comparative advantage, with too much investment in business services and resource instries and too little investment in manufacturing instries with comparative advantage. At the same time, the location distribution of FDI is too concentrated in a few countries or regions, the proportion of investment in developed areas is too high, and the proportion of investment in neighboring countries and other developing countries is too low, which deviates from the normal practice of developing countries. However, from the perspective of development, with the deepening of domestic marketization and privatization, the location distribution of FDI in China will graally approach that of other developing countries. From the regional point of view, the change of domestic regional economy has a direct impact on the investment subject, investment structure, location choice and investment efficiency of China's multinational corporations' FDI. The change of domestic regional economy has a direct impact on the location choice of foreign investment. At the same time, the political, social and economic development and changes of foreign investment places have an important impact on the location choice of FDI. With the transformation of regional economic system, the adjustment of instrial structure and the transformation of development mode, the location distribution of FDI of China's multinational corporations will graally change. Secondly, this study emphasizes the impact of institutional dependence on the location choice of Chinese MNCs' investment. There are various distortions in the FDI of China's multinational corporations. The main reasons lie in the imperfection of the domestic system, the sharp increase of domestic social risks caused by the excessive gap between the rich and the poor, the lack of protection of private property caused by the imperfection of the legal system, and the loss of a large amount of capital; Discriminatory investment, market access and financing policies, as well as excessive tax and fee burden, lead to a large amount of capital escaping from the system and eventually form a huge amount of false investment; However, excessive government intervention, unfair competition environment, long-term suspension of property rights of state-owned enterprises and widespread monopoly all lead to the survival of the poor and the elimination of the excellent, which makes enterprises lack competitiveness, unreasonable instrial structure and encourages false investment. Due to the special property right structure, incentive mechanism and soft restraint mechanism of China's FDI led by state-owned enterprises, it leads to the blindness of investment decision-making, the distortion of investment instry and the irrationality of investment location, which reces the investment efficiency. Therefore, institutional optimization is the key to improve the location distribution of FDI of China's MNCs. Thirdly, based on the expansion of Dunning's theory, this paper summarizes the rules of FDI location selection. With the development of information technology, the further refinement of the international division of labor and the complexity of the international environment of FDI, macro institutional and cultural factors have become the important influencing factors of FDI. The advantages of ownership, internalization and location have become the conditions for FDI. The comparative advantages and the comparative cost advantages of technology development have also become the important factors for the vigorous development of FDI in developing countries. These investment motives, investment objectives and location advantages are combined to form a variety of FDI location selection models. For developing countries, their FDI location choice mainly follows five principles: the principle of proximity, the principle of comparative advantage, the principle of competition and cooperation, the principle of monopoly competition and the principle of transaction cost, among which the principle of proximity and the principle of comparative advantage are the main principles. Due to China's special investment subject structure and distorted investment incentive mechanism, the location selection of China's multinational corporations' FDI mainly follows the principles of monopoly competition and transaction cost, which deviates from the normal practice of general developing countries. However, with the further promotion of China's marketization and the further enhancement of China's multinational corporations' strength, the location selection of China's multinational corporations' FDI mainly follows the principles of monopoly competition and transaction cost, The principle of FDI location selection of China's multinational corporations will be rationalized graally. Finally, this paper puts forward some suggestions to optimize the location distribution of FDI of China's MNCs. It is pointed out that only by fundamentally improving the market economic system, maintaining the market environment of fair competition, promoting the adjustment of regional instrial structure and the upgrading of instrial clusters, changing the traditional economic development mode, and continuously improving the ownership advantage of Chinese multinational companies on the basis of vigorously developing the private economy and promoting free competition, can we realize the goal of promoting the development of China's multinational enterprises, Only in this way can we form the competitive advantage and comparative advantage of China's multinational corporations' FDI, and finally optimize the main structure and instrial structure of China's multinational corporations' FDI, so as to make the location distribution of China's multinational corporations' FDI more reasonable and improve the investment efficiency

8. The era of network economy surpasses the era of instrial economy, which is characterized by ten characteristics and development trends, namely, network time and space surpasses physical time and space, network economic society surpasses instrial economic society, network economy surpasses material economy, new combination and new mechanism of proction factors, new changes in social proction mode and its value orientation, global market surpasses regional market, network economy surpasses material economy From comparative advantage to competitive advantage, from diminishing returns to increasing returns, from intellectual capital to material capital, from sustainable innovation to regulation scale.

9. Take a look at international trade (published by Renmin University of China Press) edited by Thomas pueger. These theories are explained in detail
the theory of absolute advantage emphasizes that a country should specialize in procing and exporting its own procts with absolute advantage. The so-called absolute advantage refers to the absolute high labor proctivity or the absolute low proction cost
the theory of comparative advantage means that a country should specialize in procing and exporting its own procts with comparative advantage. The measure of the so-called comparative advantage is the opportunity cost. The lower the opportunity cost, the stronger the comparative advantage. Opportunity cost is that in the case of limited resources, to increase the proction of a proct, we must give up the quantity of another proct. For example, in the case of limited time, if you play, you can't learn. The opportunity cost of playing is the knowledge increase and utility brought by learning knowledge
the theory of proction factor endowment, three sentences. That is, different countries have different factor endowments; The proportion of factor input of different procts is different; What a country should export is the procts proced intensively with its relatively rich factors
imperfect competition mainly discusses why international trade is concted under monopolistic competition and oligopoly competition Before this theory, absolute advantage theory and comparative advantage theory are based on perfect competition< The theory of scale economy emphasizes that scale economy is the cause of trade. Scale economy can be divided into internal scale economy and external scale economy The theory of proct life cycle explains the time period from the proct entering the market to the final exit from the market. With the change of proct life cycle, the direction of trade changes constantly. It's Raymond Vernon There is also a discussion in pugel's textbook)
