Based on the 2008-2017 data of 78 listed enterprises in Henan province, the relationship between corporate social responsibility and economic performance in 7 industries is measured by 8 indexes through Arellano-Bond dynamic panel data model. The research shows that the social responsibility of listed enterprises in Henan Province has a lagging impact on the economic performance of enterprises, which has a negative impact on the short-term and a positive impact on the long-term. The common point is that the responsibility of the investor has a positive impact on the economic performance of the enterprise, and other aspects vary greatly due to industry categories. In general, the degree of corporate social responsibility of listed enterprises in Henan Province is relatively low.展开更多

Based on data for the damage caused by four recent major earthquakes in Japan, we investigate the trends in the number of evacuees and evacuation centres after these disasters as well as the restoration processes for public utilities such as electricity, gas, water, and communication lines. We compare the restoration speeds and trends of the damaged infrastructure systems. We also propose various mathematical models to approximate the recovery trends using both evacuee-related data and damage recovery process data. These results can be used to design natural disaster mitigation policies not only in Japan, but also in other countries. The results of various statistical data analyses and mathematical modelling techniques are applied to provide policy suggestions.展开更多
