Literature Review

•Huang and Wang (2010) analysed 116 Chinese firms –

quality of reports has polarized, they need improvement

•Vurro and Perrini (2011) stated that level of disclosure does

not improve firm ability to manage stakeholders

•For Araya et al (2014) disclosing information would help to

reinforce stakeholders´trust.

•Kolk (2014) says there is no unequivocal way to distinguish

greenwash from realistic reporting

•Voluntary sustainability standards such as GRI and the

emergence of IR is a path of no return2015 Academy of Management ConferenceAugust 7-11Vancouver

Use of content analysis to search for specific corporate

information and reduce it into exclusive categories.

Use of GRI pre-defined categories for analyzing information

disclosed.

Each topic/information was assigned a score from 0 to 1

using the wording of the sustainability report in the following

way: no coverage (0); sketchy (0,25); systematic (0,5);

extensive (0,75) and integrated (1,0)

Empirical Dimension Analysis

Moving to hypotheses H2 to H4, correlations between the

report year and each dimension of TBL are significant for

economic and social dimensions.

So H2 and H4 were accepted – consistent improvement from

2008-2012

This improvement was not clear for Environment –

H3 was rejected

2015 Academy of Management ConferenceAugust 7-11Vancouver

Page 15: Academy of management congress 2015

Conclusion

Information disclosed in the reports

has shown consistent improvement

as well as for economic and social

dimensions

Companies are gaining experience

as years go by

2015 Academy of Management ConferenceAugust 7-11Vancouver

Page 16: Academy of management congress 2015

Conclusion

Final message:

They should use the reporting to build a meaningful

relationship with stakeholders as well as a legitimizing tool

for the Society.
