摘要：We build a two-country general equilibrium model to analyze the effects of cross-border data flows and pre-existing development gaps in data economies on each country's production and     international trade. Raw data as byproducts of consumption can be transformed into various types of working data (information) to be used by both domestic and foreign producers. Because data     constitute a new production factor for intermediate goods, a large pre-existing divide in the    developments of    domestic data economies can reduce or even freeze trade. Cross-border data  flow mitigates the    situation  and improves welfare when added to international trade.    Data-light countries where data are less important in production enjoy a ``late mover advantage''  with international trade and data flows, contributing more raw data from which the data-intensive  countries generate knowledge for  production. Furthermore, cross-border data flows can reverse the cyclicity of working data usage  after productivity shocks under small extant data divides; shocks to data privacy or flow costs   have opposite effects on domestic and international data sectors. The insights inform future    research and policy discussions concerning data divide and flow  and their implications for trade  liberalization, the data labor market, among others.
