    • Challenges and limitations of smart cities and urban brain construction in the era of AI
    • LIU Tao, FAN Yuting
    • Information and Communications Technology and Policy. 2021, 47(5): 22-25. DOI:10.12267/j.issn.2096-5931.2021.05.005
    • Abstract ( 546 )   
    • Deep learning technology leads a new wave of development of artificial intelligence. As the product of the combination of AI and urban governance, “urban brain” has become the main product that many IT companies are competing to develop and promote. Advanced technology promotes the construction of smart cities, but the limitations of the technology have also brought potential harm to the city. This paper starts with the concept of modern urban governance, analyzes the shortcomings and limitations of the current deep learning technology, and draws the conclusion that it is not feasible to control the city through technology. Excessive monitoring and data collection of various aspects of the city will cause the decline of the city􀆳s vitality and loss of autonomy.

    • Digital economy, tax distribution and coordinated development of urban and rural areas
    • XIAO Rongmei, ZHANG Jin, HUO Peng, YIN Haodong
    • Information and Communications Technology and Policy. 2021, 47(5): 26-31. DOI:10.12267/j.issn.2096-5931.2021.05.006
    • Abstract ( 350 )   
    • The digital economy has brought new opportunities and new challenges to the development of agriculture and rural areas. The dislocation distribution of the supply and demand entities of the digital economy across urban and rural areas and across regions has resulted in the imbalance of tax distribution between urban and rural areas and regions. Digital economic transaction activities have a partial substitution effect on traditional economic activities, eroding the original taxation basis of rural and underdeveloped areas, and then generating a siphon effect on taxation, which damages the tax benefits of rural and underdeveloped areas. Currently, the European Union, the United States and other developed countries and regions are exploring ways to adjust the taxation mechanism to promote the coordinated development of the inter-regional digital economy, providing some lessons for China to learn from. In the future, China needs to build a tax system compatible with the digital economy, establish a sound tax distribution mechanism based on the destination principle, strengthen the digital collection and management capabilities of tax authorities in rural and underdeveloped areas, and ensure the implementation of the destination taxation principle, further play the role of digital platforms in tax allocation, use information technology to promote industrial development, expand the tax base in rural and underdeveloped areas, and promote a more fair and reasonable tax distribution in the digital economy.

    • Information and Communications Technology and Policy. 2021, 47(5): 53-59. DOI:10.12267/j.issn.2096-5931.2021.05.011
    • Abstract ( 360 )   
    • Due to the physical limit of LDMOS devices, 5G(5th generation mobile networks) base stations began to use RF GaN devices to replace LDMOS devices. As a wide band gap semiconductor, gallium nitride can withstand higher operating voltage, which means that its power density and working temperature are higher. Therefore, it has the characteristics of high-power density, low energy consumption, high frequency and wide bandwidth. This paper analyzes the global patent distribution of GaN and GaN power amplifier from the perspectives of annual applications, applicants, geographical distribution, and technology distribution. Based on the characteristics of patent data, this paper gives some suggestions to promote the construction of intellectual property capacity of GaN enterprises in China.
