Metaverse is a collective term for all economic and social activities in the space where the physical world, digital world, and consciousness world are interactively integrated and mutually empowered. The metaverse is the advanced stage of digital civilization and the future formation of human society. The basis for developing metaverse is general digital technologies such as high-performance network, high-performance storage, high-performance computing, high-performance security, and artificial intelligence. On the basis of the above, the key to developing the metaverse lies in researching core technologies such as digital life technologies, trusted collaborative network technologies, natural interaction technologies, ubiquitous operating system technologies, technologies and methods for computational experiments, and theories and technologies for crowd intelligence science. We should take typical metaverse application scenarios as entry points, such as the key fields of agriculture, industry, service industry, military, social governance, and other economic and social areas, to break through key metaverse technologies and implement pilot demonstration projects of metaverse. Through the demonstration, we can systematically promote the application of metaverse in economy and society from point to line, and continuously iterate and evolve the metaverse technology to advance the metaverse to a higher stage. This paper systematically analyzes the current development status and future directions of metaverse from the concept, key technology, and vision of metaverse, paving the way for the subsequent research of metaverse.

Diminishing the Perception Bias in the Working Environment Using a Network Generation-Based Framework
Tsinghua Science and Technology 2024, 29 (3): 671-683
Published: 04 December 2023

Income inequality is widespread in human society and has important implications for human behavior. People’s perception of the environment bridges income inequality and individual behavioral decisions. Existing research suggests that social income inequality is usually biased, either overestimated or underestimated. However, such phenomena have not been fully explored with quantitive prove, especially in the working environment based on performance data of actual production. In fact, the correct perception of people is the basis of a fair environment for their production decisions. Thus, the perception bias may weaken the adaptability and competitiveness of a company in the market. This paper first confirms the prevalence of individual perception bias of income inequality within the working environment based on actual production data. Our results show that people tend to underestimate income inequity around them, and this underestimation grows with the real unfairness of the working environment. Further, this paper proposes a network generation-based framework with a three-layer structure to correct perception bias using a cooperative network reengineering approach. Within the framework, a homophily-based generative network model is proposed as the key algorithm. Our simulation results show that our proposed framework effectively reduces individuals’ perception bias of income inequality.

Analysis of a Firm’s Optimal Size Based on Accessible Market Capacity
Tsinghua Science and Technology 2020, 25 (5): 659-667

E-commerce has dramatically reduced the limitation of space and time on economic activities, resulting in individuals having access to a huge number of consumers. In this paper, we propose a company’s optimal size decision model containing management costs as a means of investigating the evolution of the company size in e-commerce. Given that production decisions are made based on accessible market capacity, we explain how a company enters the market, and we draw an evolutionary path of the optimal company size. The results show that in the early expansion stage of accessible market capacity, a firm’s optimal size keeps increasing; after reaching a peak, the change in a firm’s optimal size depends on its cost management. When the accessible market capacity reaches a threshold, the firm will no longer be in the market, and may no longer exist. Finally, we construct a simulation framework based on complex adaptive systems to validate our proposed model. A simulation experiment confirms our model and reveals the dynamic co-evolution process of individual producers and firms.

Architecture of Next-Generation E-Commerce Platform
Tsinghua Science and Technology 2019, 24 (1): 18-29

E-commerce, driven by computer and internet technology, has experienced a significant growth in almost all fields during the past two decades. E-commerce has significantly changed the rules of business. Numerous research institutions and enterprises have made e-commerce more intelligent and convenient. Here, we propose a novel prototype of next-generation e-commerce platform with an architecture framework and theoretical models. Each subject, including the individual, enterprise, and administrative department, has his/her personalized portal to complete the subject information synchronization, supply release, demand satisfaction, and social contact. By using the personalized portal, instead of the traditional trading platform, the consumers and suppliers can complete intelligent matching transactions without intermediate traders. Moreover, the overall transaction process can be reviewed, making the transaction safer, more transparent, and more interesting. Moreover, the interconnected personalized portals solve the isolated islands of information, and the counterparts support parallel processing. Thus, this may improve the operating efficiency of the entire society.

Analysis of Specialized Production of Transaction Services Based on Essential Services Quantity
Tsinghua Science and Technology 2017, 22 (5): 529-538
Published: 11 September 2017

The specialized production of e-commerce transaction systems is an important research topic, which is of great significance for evaluating the development level and forecasting the development direction of e-commerce. However, there is a certain disparity between the current mainstream research model and reality, which leads to a deviated result. This paper puts forward a definition of “transaction efficiency” based on essential transaction services and establishes a model of the middleman’s specialized production decision of transaction services. The research result shows that (1) transaction efficiency plays an important role in improving the middleman’s specialized production level, (2) only when the transaction efficiency is higher than a certain threshold will the distribution middleman appear, and (3) the degree of economic specialization, price of commodities and transaction services, and other associated factors also affect the evolution of e-commerce transaction systems.

Purpose

Material conscious and information network (MCIN) is a kind of cyber physics social system. This paper aims to study the MCIN modeling method and design the MCIN-based architecture of smart agriculture (MCIN-ASA) which is different from current vertical architecture and involves production, management and commerce. Architecture is composed of three MCIN-ASA participants which are MCIN-ASA enterprises, individuals and commodity.
