Data Flow&Transaction Mode Classification and An Explorative Estimation on Data Storage&Transaction Volume

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.

Green Energy Development System under the Background of Environmental Sustainability

With the continuous advancement of economic globalization,energy demand is expanding and energy consumption is excessive,which leads to energy shortage.Unreasonable energy use also brings great challenges to the environment and affects the balance of the ecosystem seriously.The rise of the third industrial revolution has injected new vitality into energy system.The construction of energy Internet system,which integrates Internet technology and energy technology,has become a new energy system of sustainable development.It has put forward the reform scheme for the mismatch of energy demand points and environmental pollution.The deepening of sustainable development strategy accelerates the promotion of energy Internet system,promotes the large-scale utilization and sharing of renewable energy.It also provides a new idea for realizing green energy structure and efficient energy utilization.Firstly,based on the core concept of energy Internet system,this paper reviews the relevant research on energy Internet system in academic and industrial circles,and gives the preliminary definition of energy Internet system market.On this basis,it puts forward the development goal of energy Internet system market.It compares the new energy Internet system market with the traditional single energy market,highlighting the characteristics of energy Internet system market,it is reflected in the diversified transformation of market trading subjects,the diversification of market trading objects,the increasing dependence of information technology and the improvement of the matching degree of supply and demand.Then,the integrated architecture of of the energy Internet system market is carried out,and the issues related to the transaction mode and operation mechanism of the energy Internet system market are discussed.Finally,the frontier problems of energy Internet system market are summarized,and the research prospect of energy Internet system market is put forward.

Impacts of Corporate Culture on Merger

By studying the cultural background and corporate culture in China, Japan and USA, this paper analyzes the effects of cultural background and corporation culture on the transaction cost and the efficiency of control right, thus shows that cultural backgrounds have great impact on merger. This paper further studies the choice and application of the mode of culture combination of the transnational merger.

An application-semantics-based relaxed transaction model for internetware

An internetware application is composed by existing individual services, while transaction processing is a key mechanism to make the composition reliable. The existing research of transactional composite service （TCS） depends on the analysis to composition structure and exception handling mechanism in order to guarantee the relaxed atomicity. However, this approach cannot handle some application-specific requirements and causes lots of unnecessary failure recoveries or even aborts. In this paper, we propose a relaxed transaction model, including system mode, relaxed atomicity criterion, static checking algorithm and dynamic enforcement algorithm. Users are able to define different relaxed atomicity constraint for different TCS according to application-specific requirements, including acceptable configurations and the preference order. The checking algorithm determines whether the constraint can be guaranteed to be satisfied. The enforcement algorithm monitors the execution and performs transaction management work according to the constraint. Compared to the existing work, our approach can handle complex application requirements, avoid unnecessary failure recoveries and perform the transaction management work automatically.
