ハイライト:
-
県境を越える移動者の数は、最初の緊急事態宣言(SOE)で最も減少し、その後のSOEではその減少規模は小さかった。
-
Go To トラベルキャンペーン期間中は、県間移動に伴うネットワークの近接性が増加した。
-
パンデミック時、地理的に近い都道府県間の移動よりも遠い都道府県間の移動が減少した。
-
パンデミック時、都道府県間の近接性の増加は、COVID-19感染率の上昇と相関していた 。
Highlights:
-
The number of inter-prefectural travelers decreased most during the first state of emergency (SOE), but less with each subsequent SOE.
-
There was an increase in the number of travelers and inter-prefectural connectedness during the Go To Travel campaign.
-
Travel between distant prefectures decreased more than that between prefectures with geographic proximity during the pandemic.
-
Increased inter-prefectural “connectedness” was correlated with higher rates of COVID-19 infection for the entire pandemic period.
