Research on the Impact of Digital Products and Service Trade on the National Economy
Based on input-output table data,this paper measures the economic effects of digital prod-uct and service exports from a demand perspective and the economic effects of digital product and ser-vice imports from a supply perspective.The research constructs a partial-closed model on the basis of es-tablishing a digital economy input-output table,using an adjusted Leontief model to calculate the nation-al economic output and value-added driven by digital product and service exports,and an adjusted Ghosh model to calculate the national economic output and value-added promoted by digital product and service imports.The results show that trade in both digital products and services has a positive impact on the national economy,with the demand-side effect exceeding the supply-side effect.
