    • Abstract ( 4474 ) 　　
    • Digital economy has become a new driving force for global economic development and a major strategy of China. During the “ 13th Five-Year Plan ” period, China's digital economy has continued to expand and its contributions have continued to increase. The support for digital industrialization has become more solid, the pace of industrial digitization has accelerated, and digital governance has advanced. The pragmatic advancement of international cooperation has played an important role in fighting the impact of the epidemic. It should also be noted that compared with the high-quality development requirements of the digital economy, and compared with the international advanced level, China's digital economy still has many gaps in terms of technological foundation, digital transformation degree, and digital governance level. Looking forward to the 14th Five-Year Plan, the new development pattern will provide broad space for the development of the digital economy. After a brief decline in the impact of the epidemic on the digital transformation of enterprises, it will enter a new stage of accelerated development of comprehensive expansion and in-depth expansion. The digital transformation of government governance will be accelerated in terms of application fields, technical capabilities, data capabilities, collaboration capabilities, and service capabilities. The legal construction of the digital economy will be further supplemented and improved, and legislation exploration in key areas, emerging areas, and foreign-related fields will continue to be strengthened.

    • Problems of digital economic governance fragmentation and countermeasures
    • LI Yongjian
    • Information and Communications Technology and Policy. 2021, 47(2): 8-14. DOI:10.12267/j.issn.2096-5931.2021.02.002
    • Abstract ( 455 ) 　　
    • In recent years, with the rapid development of China􀆳s digital economy, digital technology has penetrated into all aspects of social economy, playing a significant role in promoting economic growth. The application of digital technology to various industries produces a large number of policy problems, and the resource fragmentation of digital economy governance is serious. Therefore, many think tanks proposes the establishment of a “unified digital economy supervision department ” . From the current management system of digital economy in China, the government departments are too fragmented in the supervision and promotion of digital economy, which has brought some adverse effects on the development of digital economy. This paper suggests that China should establish a “National Digital Economy Promotion Committee” to be responsible for the formulation, implementation and supervision of digital economy promotion policies.

    • Research on Japan's digital transformation policy in the post COVID-19 era
    • HUA Jinling
    • Information and Communications Technology and Policy. 2021, 47(2): 22-31. DOI:10.12267/j.issn.2096-5931.2021.02.004
    • Abstract ( 570 ) 　　
    • This paper reviews Japanese government's digital transformation policies and systems after 2000, including 20-years digital government implementation plan. Problems faced by the unique identification card and living allowance payment during the COVID-19 have exposed the shortcomings and challenges of Japan's past digital policies. Lessons from this constitute the starting point for the new Japanese government to promote its digital transformation policy in the post COVID-19 era. This article also clarifies three major directions of Japan's digital transformation policy in the post COVID-19 era: reducing mobile communication tariffs, implementing 5G promotion plans, and setting up an independent digital agency. Based on the findings of a series of mobile communication industry's reform measures introduced by the Japanese government in the post COVID-19 era, this article further considers the necessity and significance of Japan's digital transformation policy and addresses the structural problems of the Japanese mobile phone industry hidden behind the system.

    • Research on the ethical risk and governance system of Artificial Intelligence in the digital economy era
    • WANG Yifei, HAN Kaifeng
    • Information and Communications Technology and Policy. 2021, 47(2): 32-36. DOI:10.12267/j.issn.2096-5931.2021.02.005
    • Abstract ( 795 ) 　　
    • With the innovation of machine learning algorithms, the accumulation of massive data, and the improvement of calculate ability, the new round of Artificial Intelligence ( AI) development is coming. While AI technology improves people's lives, it also triggers a series of social ethical risks and brings new social governance challenges. The paper combs and analyzes the progress and characteristics of AI governance in important countries around the world.The paper also suggests building a complete AI governance system from three aspects of governance models,governance methods, and governance evaluation. At last, the paper makes several relevant policy recommendations on how to construct AI governance system.

    • Information and Communications Technology and Policy. 2021, 47(2): 56-62. DOI:10.12267/j.issn.2096-5931.2021.02.010
    • Abstract ( 344 ) 　　
    • New technologies such as big data, artificial intelligence and blockchain are emerging one after another,which have a significant impact on the industry's innovation, productivity and competitiveness. They are widely integrated with traditional industries and spawn new industries, new formats, and new models constantly. In order to measure the development status and economic contribution of these new technologies and fields, the paper proposed to measure the industrial scale of emerging fields through value-added measures and split the industrial scale into core and integrated parts. Based on the mapping relationship between emerging fields and national economy classification, authoritative data and industry research data, the paper established an industrial scale measurement method in emerging fields by using the combination of value-added multiplier method and input-output method or proportional inference algorithm. In the end, practice was carried out in the fields of artificial intelligence and blockchain, respectively, to further verify the scientificity and practicability of the method.

    • Nonreciprocal filter based on spatiotemporal modulation with frequency reconfigurability
    • ZANG Jiawei, WANG Shouyuan, AN Shaogeng, MENG Meng
    • Information and Communications Technology and Policy. 2021, 47(2): 74-78. DOI:10.12267/j.issn.2096-5931.2021.02.013
    • Abstract ( 260 ) 　　
    • Nonreciprocal components are exclusively achieved today through magnetic materials to break time-reversal symmetry. These components suffer from the drawbacks inherent to ferrite media, namely bulkiness, high cost,incompatibility with integrated circuit fabrication processes, difficulty in circuit integration. With regard to the issues associated with the nonreciprocal components, the aim of this paper is to break time-reversal symmetry, achieve nonreciprocal electromagnetic wave propagation and realize magnetic-free integrated nonreciprocal filter based on spatiotemporal modulation. Frequency reconfigurability can be achieved by controlling the DC voltages loaded to the time-modulated resonators. The proposed nonreciprocal filter integrates the property of filter and oscillator, which permits the directional propagation of in-band signals and suppresses out-band interference, showing exotic
      functionality.
