摘　　要：基于投入产出表数据,从需求视角出发测算数字产品与服务出口的经济效应,从供给视角出发测算数字产品与服务进口的经济效应。在建立数字经济投入产出表的基础上构建局部闭模型,用调整后的Leontief模型测算数字产品和服务出口拉动的国民经济产出量和增加值,用调整后的Ghosh模型测算数字产品和服务进口推动的国民经济产出量与增加值。测算结果显示,数字产品和数字服务贸易都能对国民经济运行产生积极影响,且两者需求侧拉动作用大于供给侧推动作用。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.
