跨境数据流动限制对自然灾害经济损失的影响

The Impact of Cross-border Data Flow Restrictions on Economic Losses from Natural Disasters

进入数字化时代,跨境数据交互共享已成为自然灾害治理的核心影响因素。利用2004—2019年世界主要经济体的跨境数据流动限制数据和自然灾害损失数据进行实证分析,结果表明跨境数据流动限制程度与自然灾害经济损失之间存在显著正相关性。进一步研究表明,跨境数据流动限制是通过阻碍信息技术交流共享这一机制来影响自然灾害经济损失的。此外,跨境数据流动限制对自然灾害经济损失的影响存在一定异质性,在灾害类型层面,气象灾害与地球物理灾害中的经济损失受跨境数据流动限制的影响更为显著且强烈;在经济体类型层面,相较于发展中经济体,发达经济体中跨境数据流动限制对自然灾害损失的影响更小。研究结果拓展了跨境数据流动理论在灾害经济领域的运用,为各国在自然灾害防治领域建立更加开放和高效的信息共享机制提供一个参考。

In the digital age,cross-border data interaction and sharing have emerged as pivotal influencing factors in natural disaster governance.An empirical analysis utilizing data on cross-border data flow restrictions and natural disaster losses from major economies worldwide between 2004 and 2019 reveals a significant positive correlation between the degree of these restrictions and the economic losses incurred from natural disasters.Further investigation indicates that cross-border data flow restrictions impact the economic losses of natural disasters primarily by hindering the exchange and sharing of information technology.Additionally,there exists heterogeneity in the influence of these restrictions.Specifically,their impact is more pronounced and intense in meteorological and geophysical disasters compared to other types of natural disasters.Furthermore,the influence of cross-border data flow restrictions on natural disaster losses is less significant in advanced economies than in developing economies.The results broadened the application of cross-border data flow theory in the field of disaster economics,providing a reference for countries to establish more open and efficient information sharing mechanism in the field of natural disaster prevention and control.
