Abstract
The purpose of this paper is to understand business ethics through a Corporate Social
Responsibility（ CSR） of electric equipment manufacturers in the nuclear power industry
before and after the Great East Japan Earthquake and using text mining analysis. We
critically review previous research on the definition of CSR, and on strategic corporate
social responsibility （CSR） and creating shared value by Porter and Kramer （2006,
2011）, and find that these studies were based on theoretical normativism （Clegg,
2007）. There are certain difficulties in describing and analyzing practices derived from
the a priori norms established by environmental business ventures. For this theoretical
problem, we use text mining analysis to examine the practice of corporate business
ethics. Consequently, we find pathdependence in corporate behavior.
