    • Research on spatial grid framework and GDS data platform technology of digital twin city
    • CHENG Chengqi, QU Tengteng, LI Lin
    • Information and Communications Technology and Policy. 2020, 46(3): 1-8.
    • Abstract ( 410 ) 　　
    • In view of the bottleneck problems of unified spatial framework and efficient data organization in digital twin ciy, this study, under the guidance of the new earth geospatial subdivision theory and the corresponding national standards such as “Earth􀆳s Surface Spatial Grid and Code” (GJB8896-2017) , “Beidou Grid Code (BGC)” and “Geospatial Grid Encoding Rule”, proposes to develop an spatial grid framework for the digital twin city and the GDS (Grid Data System) data platform technology. The multi-scale 3D urban grid space is an objective existence of theearth space. Everything in the city must fall  into one or several grid bodies at a certain time. The GDS technology developed from this is oriented to unified organization of spatial data, which is conductive to the development of a new type of G-GIS, G-BIM system and is an innovative exploration of the traditional BIM, GIS and other object-oriented modelling systems. This research could help to realize the unified and efficient collection, association and calculation of urban spatial data, and is of theoretical and practical significance for supporting the construction of digital twin city.

    • Innovate the development of Supply Chain Finance and expand financing channels for SMEs
    • ZHU Li
    • Information and Communications Technology and Policy. 2020, 46(3): 66-69.
    • Abstract ( 291 ) 　　
    • At present, China has formed three typical models : Supply Chain Financial model that is dominated by core companies in the supply chain, Supply Chain Financial model that is dominated by e-commerce platform service providers, and Supply Chain Financial model that is dominated by logistics companies. But on the whole, Supply Chain Finance still faces information asymmetry, insufficient risk controlling, and the lack of special laws and regulations. Therefore, increasing the application of emerging technologies such as blockchain technology in the field of Supply Chain Finance, encouraging financial institutions such as commercial banks to strengthen innovation in Supply Chain Financial products and services, and researching and promulgating laws and regulations specific to the characteristics of Supply Chain Finance development are important measures for the healthy development of Supply Chain Finance and the ability to meet the financing needs of SMEs.

    • Influences and suggestions of the COVID-19 on China‘s digital economy investment
    • WANG Mingzhu
    • Information and Communications Technology and Policy. 2020, 46(3): 70-73.
    • Abstract ( 382 ) 　　
    • The COVID-19 spread rapidly to the whole country, which had a great impact on our economic and social development. Digital economy investment plays a key role in the development of economy because of its obvious effects of driving economic growth in a short period. In the short run, the COVID-19 will make an impact on the whole digital economy investment, industrial digital transformation investment, private investment and foreign direct investment. In the long run, the impact of the COVID-19 on digital economy investment is not sustainable. Once the COVID-19 is brought under control, the scale of digital economy investment will continue to expand, and new models and new forms of business, industrial digital transformation and digital governance will become the hot areas of investment. So the government should help enterprises to tide over the difficulties which are greatly affected by the COVID-19 using its financial measures. In the long run, we should strengthen investment guidance in the digital economy, activate private investment in the digital economy, and optimize the investment environment in the digital economy.

    • YUE Yunsong
    • Information and Communications Technology and Policy. 2020, 46(3): 74-77.
    • Abstract ( 361 ) 　　
    • As the WHO has identified the COVID-19 epidemic as an “international public health emergency”, many countries have announced measures to impose immigration controls on China, suspend flights, and restrict import and export goods. China􀆳s foreign trade is under tremendous pressure from both inside and outside. Unlike the SARS outbreak in 2003, China􀆳s digital trade has further developed and matured, and it is playing an important role in
      stabilizing foreign trade and promoting resumption of work. China should further promote the digital transformation of the way trade is conducted, encourage support for the export of digital products and services, and accelerate the improvement of the digital service trade governance system.
