Trends and Challenges of Informatization

In recent years, information and communication technology (ICT) has obtained sustained and rapid development in the world, and has become the main driver of economic growth in a global scope. ICT’s development level is closely linked to GDP. Information and communication industry enters the new stage in which integrated innovation promoting integration development, and in which new features are presenting, such as integration, groups and integrated innovation. Information security and information infrastructure security have become an important part of national security. The informatization construction in China still faces many problems and challenges, such as relatively lag-ging behind of our policies for promoting the development of informatization, the lack of original innovation and core technologies. Barriers in the development need be tackled, Cyberspace strategy research needs to be strengthened and national network and information security situation is severe. The rapid development of Internet put more severe challenges on network governance. So the suggestions to these problems are as follows: to pro-mote the next generation Internet as the core of the information infrastructure, continue to promote the depth of integration of information technology and industrialization, increase R & D investment, develop the core technol-ogy of information industry, improve people's quality of informatization, and focus on promoting the construction of education informatization.     

Economic Fluctuation Mechanism and Macroeconomic Policies under Informatization

Based on the micro-foundation of adverse selection, moral risk and principal-agent models, imperfect information can cause real economic fluctuation through imperfect market, price distortion and/or expectation, especially profoundly impacting microeconomic agents’ expectation, macroeconomic policy making and macroeconomic policy effect through expectation. In international economic relations, imperfect information is exhibited not only in information divide between developed countries and developing countries, but also in developed countries’ comparative advantage in product information. When meeting the needs of information economy and confronting asymmetric structure of international information, China’s macroeconomic management should attach more importance to information infrastructure, and improve formation and conduction mechanism of macroeconomic policies, so as to make full use of information guide to play active role in stabilizing economic fluctuation and preventing possible contagion of international crisis.     

Engineering Construction of Military Supply Chain on the Basis of Informatization Warfare

The modern warfare is more dependent on the war energy. It is not only focus on the use of high-tech, including information technology and other tools, to increase the efficiency in the use of war energy in the battlefield, but also work on the conversion efficiency and quality from the economy energy to the war energy. In this regard, we shall pay particular attention to military acquisition which is acting as a bridge in the process of transition from economy energy to war energy. The acquisition department will be in close contact with other functionalities, e.g.: logistics, technology support and other services departments to display the supporting function of the military supply chain in future battlefield. The modern information warfare is becoming to be more and more stereoscopic with a high speed pattern which is in depth and excluding the line operation. It is driving the war movement into a multi-dimensional area. The original line-operation model, i.e. working on the front line, did not exist any more. The joint service on war is much more preferred. The recent practice showed that the logistics support is expected to play a very special role in the future war. No matter how advanced the weaponry will come to be, as long as there is no immediate, sufficient and precise support from logistics side, the tactical arrangements/operations as well as the combat effectiveness cannot be commenced smoothly. The information technology as a philosophy, which is influencing and infiltrating the various fields of this era, is maturing itself in a dynamic development. In the field of logistics support, the application of information technology is an enhanced technology to develop the resource space, improve the efficiency of allocation and to ensure an effective materials transportation and resource usage. The main focus and further development of information technology is aiming at achieving the optimal efficiency in military economy by constructively settling the complicated relationship between the military supply chain and external environment which are connected to the other in a systematic way to maintain a smooth and well-ordered operation of supply-chain system. To start with the supply chain construction, firstly we shall be clear that the logistics acquisition is playing a crucial role in the military supply chain. Secondly we shall set up an effective operating mechanism for the cooperation between market and military. At the same time, we shall put our efforts in strengthening the organizational functions of the supply chain and its supporting capabili-ties, and demonstrating the forces constitute, work distribution, command system and operational models in the logistics support. As a consequence, everybody will have the same clear understanding on the requirement of the supply chain construction which will be adaptable to the needs of future battlefield.

Impact of Informatization on Economic and Social Development in China

Informatization is the process of information revolution and its impact on economy and society. During the process, traditional labor force, labor tools, labor subject as well as the production mode and structure are changed. Informatization appeared under the background of the Second Industry Revolution and the Third Industry Revolution, when computer, Internet and artificial intelligence technology was introduced. China is undergoing tremendous economic and social transformation. Informatization will influence Chinese economy by transforming its economic mode, boosting long-term economic development, changing economic structure and reforming economic institution. Meanwhile, it will also affect Chinese society by pushing social progress, changing social structure, transforming social development mode and reforming social institution.     

Impact of Informatization on Macro Economy and Finance in China

The process of Informatization will have great impact on both macro economy and finance. In the respect of macro economy, informatization influences short-term economic fluctuation, the growth of total economic scale and economic structure in China. Firstly, it will influence short-term economic fluctuation by affecting labor market, pricing fluctuation, short-term investment and consumption, as well as the implementation of macroeconomic policy. Meanwhile, it will boost long-term economic growth by providing new production factors, upgrading production efficiency and pushing technology innovation. In addition, it will change economic structure by impacting industry structure, demand structure and regional structure. On the perspective of finance, informa-tization has changed the monetary form and function, which is the technological foundation of virtual currency and electronic payment. It exerts an extensive and far-reaching impact on the financial institutions, financial mar-ket, financial supervision and regulation through two ways: decreasing the transaction costs and alleviating the asymmetric information problems.
