Build and Strengthen China`s Information Tech-system

Abstract

Self-reliance and self-strengthening at high level does not depend on a single technique, but on the formation of an advantageous national tech-system, so called "country-as-a-platform". Information tech-system refers to the whole one that closely connects devices, components, complete machine, system software, middleware, and application software with a series of technical standards and intellectual property rights. We are entering the IT 3.0 era characterized by integration of human-cyber-physical world. The IT 3.0 era will certainly produce a new tech-system different from the IT 1.0 and IT 2.0 eras, which is a rare opportunity for China to build a self-reliance and self-strengthening tech-system. In the future, the information industry ecology will develop in the direction of domain-specific oriented and China's advantages will be fully reflected in the future competition. The following principles should be paid attention to in the construction of information techsystem:(1) correctly deal with the dialectical and unified relationship between self-reliance and open cooperation. We should actively integrate into the global innovation network and make China a broad stage for global scientific and technological opening and cooperation. (2) Before revolutionary devices enter the market on a large scale, the hope of improving computer performance and energy efficiency mainly lies in the innovation of architecture. We should focus on the development of cross layer vertical optimization technology in various fields, and defeat the once mainstream general-purpose chips with acceleration chips and systems suitable for different scenarios. (3) Develop open source ecology and build a community of technological destiny. Open source is not only an effective way to win the strong with the weak and break the technology monopoly, but also an important way to build a self-reliance and self-strengthening tech-system in China. (4) Mainly develop domain specific industrial ecology. The information field has an important characteristic different from other fields:the new market is much larger than the old market. Large market means many innovation scenarios, and the future market of a subdivided field can form a large enough industrial ecology. Another feature of China is that there are many developers, we therefore have the natural advantage in development of domain-specific architecture (DSA). (5) Vigorously develop agile design and agile manufacturing. The cost of chip design is very high, which cause high professional threshold. In the era of ubiquitous interconnection, there is a sharp contradiction between the high demand for chips and the high cost of chip design. Agile design is the most effective way to deal with fragmented application scenarios. This paper briefly introduces eight articles on this special issue of "Build and Strengthen China's Information Tech-system". These articles focus on the choice of future technology direction and scientific research mode, which to a certain extent reflects the efforts and expectations of Chinese scientific and technological researchers to explore and establish a new information tech-system.
