The public has shown great interest in the data factor and data transactions,but the current attention is overly focused on personal behavioral data and transactions happening at Data Exchanges.To deliver a complete picture of data flaw and transaction,this paper presents a systematic overview of the flow and transaction of personal,corporate and public data on the basis of data factor classification from various perspectives.By utilizing various sources of information,this paper estimates the volume of data generation&storage and the volume&trend of data market transactions for major economies in the world with the following findings:(i)Data classification is diverse due to a broad variety of applying scenarios,and data transaction and profit distribution are complex due to heterogenous entities,ownerships,information density and other attributes of different data types.(ii)Global data transaction has presented with the characteristics of productization,servitization and platform-based mode.(iii)For major economies,there is a commonly observed disequilibrium between data generation scale and storage scale,which is particularly striking for China.(i^v)The global data market is in a nascent stage of rapid development with a transaction volume of about 100 billion US dollars,and China s data market is even more underdeveloped and only accounts for some 10%of the world total.All sectors of the society should be flly aware of the diversity and complexity of data factor classification and data transactions,as well as the arduous and long-term nature of developing and improving relevant institutional systems.Adapting to such features,efforts should be made to improve data classification,enhance computing infrastructure development,foster professional data transaction and development institutions,and perfect the data governance system. 展开更多

Association rule mining methods, as a set of important data mining tools, could be used for mining spatial association rules of spatial data. However, applications of these methods are limited for mining results containing large number of redundant rules. In this paper, a new method named Geo-Filtered Association Rules Mining(GFARM) is proposed to effectively eliminate the redundant rules. An application of GFARM is performed as a case study in which association rules are discovered between building land distribution and potential driving factors in Wuhan, China from 1995 to 2015. Ten sets of regular sampling grids with different sizes are used for detecting the influence of multi-scales on GFARM. Results show that the proposed method can filter 50%–70% of redundant rules. GFARM is also successful in discovering spatial association pattern between building land distribution and driving factors. 展开更多

Data is the primary factor of production in the digital economy,playing a role in promoting the deep integration of the digital economy and the real economy and smoothing the national economic cycle.After entering the circulation system of the real economy,data is rapidly integrated into production,circulation,consumption,distribution,and other links.It optimizes resource allocation,unblocks circulation channels,promotes accurate matching of supply and demand,stimulates emerging demand,and forms a virtuous circle of digital technology application,traditional physical enterprise transformation,and technological innovation.Integrated development is an important feature of the digital economy.Data promotes the integration of factors of production,products,enterprises,industries,and markets,which fosters a circular system with deep integration of the digital economy and the real economy.To promote the deep integration of the digital economy and the real economy,the government and business entities should take measures to improve the circular efficiency of the digital economy and the real economy.These measures include attaching importance to the role of data-driven development,improving data capacity,data development,and utilization in enterprises,exploring diverse circulation models of enterprise data,and creating typical application scenarios and industrial data spaces. 展开更多

Since data services are penetrating into our daily life rapidly, the mobile network becomes more complicated, and the amount of data transmission is more and more increasing. In this case, the traditional statistical methods for anomalous cell detection cannot adapt to the evolution of networks, and data mining becomes the mainstream. In this paper, we propose a novel kernel density-based local outlier factor(KLOF) to assign a degree of being an outlier to each object. Firstly, the notion of KLOF is introduced, which captures exactly the relative degree of isolation. Then, by analyzing its properties, including the tightness of upper and lower bounds, sensitivity of density perturbation, we find that KLOF is much greater than 1 for outliers. Lastly, KLOFis applied on a real-world dataset to detect anomalous cells with abnormal key performance indicators(KPIs) to verify its reliability. The experiment shows that KLOF can find outliers efficiently. It can be a guideline for the operators to perform faster and more efficient trouble shooting. 展开更多

The industrial ecosystem covers the advanced technologies,key industries and core factors in the process of developing new quality productive forces,serving as an important perspective for investigating the development of new quality productive forces.Based on the analytical framework comprising technologies,industries and factors,this study examines the internal logic of the development of new quality productive forces.Firstly,the four industrial revolutions in history demonstrate that the industrial ecosystem has promoted a series of revolutionary technology innovations.Secondly,the industrial ecosystem promotes the formation and development of emerging industries through resource sharing,knowledge spillover,and technology diffusion.Thirdly,the industrial ecosystem achieves an innovative allocation of factors of production through the dynamic feedback loop mechanisms of data-algorithm-traffic and data-network-activity.The industrial ecosystem consists of three subsystems,including the innovation ecosystem,the business ecosystem,and the platform ecosystem.The three subsystems transcend the boundaries of innovation for new quality productive forces,broaden their application scenarios,and enhance the efficiency of factor allocation,respectively.To further advance the development of new quality productive forces,it is necessary to establish a system ensuring the coordinated development of all factors.Additionally,efforts are required to integrate the dual driving forces of technology innovation and institutional innovation,and enhance the integration of four chains,including the innovation chain,the industrial chain,the capital chain,and the talent chain. 展开更多

As a new form of social wealth,digital wealth is becoming an important force in the promotion of common prosperity.In the digital economy era,digital labor and data factors are important sources for creating digital wealth.The creation of digital commodity wealth is reflected in the process of value formation and value appreciation of digital goods,as well as in the expansion and reproduction process of data production factors.The creation of digital non-commodity wealth needs to rely on the coordination of multiple supply systems including government,enterprises,society and platforms.In the distribution of digital wealth in a socialist market economy,it is necessary to adhere to the basic distribution system with remuneration based on work as the main form and the coexistence of multiple distribution methods.It should fully reflect the value contribution of data factors while also addressing and resolving potential polarization effects caused by the distribution of digital wealth.On the basis of the new development stage,China should steadily advance the creation and accumulation of digital wealth on the basis of constantly strengthening,improving and expanding the digital economy,and should pay attention to standardizing the distribution of digital wealth in order to achieve a solid advance in the common prosperity of all the people. 展开更多
