International tourism and global biodiversity risks
研究了2001-2019年155个国家的数据，发现国际旅游增长显著提升目的地及邻国的生物多样性风险，且影响有滞后和累积效应，政府监管和国际援助可缓解风险。
The impact of international tourism on biodiversity risks has received considerable attention, yet quantitative research in this field remains relatively limited. This study constructs a biodiversity risk index for 155 countries and regions spanning the years 2001 to 2019, analyzing how international tourism influences biodiversity risks in destination countries. The results indicate that the growth of international tourism significantly elevates biodiversity risks, with these effects displaying both lagged and cumulative characteristics. Furthermore, spatial analysis shows that international tourism also intensifies biodiversity risks in neighboring countries. The extent of its impact varies according to the tourism model and destination. In addition, government regulations and international financial assistance play a crucial role in mitigating the biodiversity risks associated with international tourism.
