RESILIENCE IN INDUSTRIAL SECTOR UNDER POWER SHORTAGES AFTER THE GREAT EAST JAPAN EARTHQUAKE

Abstract

The power shortages following the Great East Japan Earthquake create persistent impacts on Japanese industries. The firms which are not only located in the severely damaged area but also outside the area had to reduce power usage both at peak and total and spent considerable efforts to achieve the target amount of power consumption. The firms' inherent and adaptive ability to reduce the impacts of power shortages are regarded as “resilience” and the characteristics of resilience under power shortages revealed by the disaster should be immediately learned and even measured as precious lessons. This study quantitatively analyzes the relationship between the production output and power usages in 2011 and 2012 in Kanto and Kansai regions by time series analysis and find the sources of resilience against power shortages.
