Abstract
Sustainable management and corporate sustainability communication (CSC) have become central themes in both research and practice. Within sustainability reports, CEO messages serve as strategic communication channels that reveal how firms construct legitimacy and align with environmental, social, and governance (ESG) imperatives. Despite their importance, limited research has compared these messages across institutional contexts. This study aims to uncover institutional differences in CEO messages within sustainability reports of Korean and global firms. For this purpose, this study analyzes CEO messages from 343 Korean and 323 global sustainability reports (from Fortune Global 500 firms following GRI standards) using text mining techniques (e.g., semantic network analysis, word embedding, and topic modeling). Results of semantic network analysis show that Korean firms emphasize management (centrality = 0.345922), growth (0.32013), and market (0.152733), while global firms highlight community (0.362553), customer (0.331332), and commitment (0.182617). Word embedding indicates that the terms “sustainability” and “stakeholder” are linked to symbolic gratitude and external recognition in Korean messages, but to citizenship and responsibility in global ones. Topic modeling reveals four performance- and evaluation-oriented themes in Korean firms versus three execution- and long-term value-oriented themes in global firms. These findings show how different levels of institutionalization shape CEO discourse and suggest that Korean firms rely more on symbolic legitimation, while global firms stress substantive sustainability commitments.

Sustainability reporting in the light of corporate social responsibility development: economic and legal issues
Problems and Perspectives in Management Volume 15, 2017 Issue #1 (cont.) pp. 166-174 Views: 2331 Downloads: 1037 TO CITE АНОТАЦІЯIndependent audit assurance of sustainability reporting is the basis for increasing the credibility of the stakeholders, its transparency and reliability; it is a means of implementing legal liability of the company and the evidence of achievement of its legitimacy to the public. The bases for providing such assurance are the standards of implementation of audit tasks in the sphere of sustainable development. Comparative analysis of international practice as for assurance regarding the SR with local realities, based on the reporting database of Ukrainian GRI companies for the 2005-2014 years, witnessed the initial phase of such practices among Ukrainian companies, and the need to strengthen regulatory efforts to determine the legal status of SR auditing standards in Ukraine, ensuring a legal environment and the development of corporate social responsibility initiatives.

Problems and Perspectives in Management Volume 19, 2021 Issue #3 pp. 70-84 Views: 1282 Downloads: 443 TO CITE АНОТАЦІЯThe ambitious goals of environmental sustainability stated in international agreements and national programs require developing strategies to achieve them. At the same time, there is a lack of empirical evidence on the environmental performance factors, which can be purposefully changed to achieve an effective result in the short and medium-term. The paper aims to find the institutional factors of national environmental performance, including financial ones, which might be effectively used as environmental sustainability management tools. For this, the relationships between the Environmental Performance Index (EPI), as the dependent variable, and the indicators of control of corruption, the effectiveness of an anti-monopoly policy, financial opportunities, undue influence, corporate culture, innovation output, GDP, and income growth among the poorest population, using a sample of 81 countries, and the technique for constructing nonlinear regression models based on the normalizing transformations for non-Gaussian data were studied.
The study findings show that environmental performance can be predicted with sufficient accuracy by a linear model of its dependence on corruption control, minority shareholders protection, judicial independence, favoritism in decisions of government officials, tax incentives, ease of access to loans, and innovation output. Adding GDP per capita to the explanatory variables of the EPI model does not significantly affect the result accuracy but changes the model shape from linear to nonlinear. The paper substantiates ways to apply results for institutional reforms and sustainability management, such as inflation targeting, public credit guarantee schemes, performance-based loans, etc. -
Repurposing support tendered youth owned Small, Medium, and Micro-Enterprises in urban agri-business sector in Durban
Problems and Perspectives in Management Volume 18, 2020 Issue #4 pp. 437-447 Views: 929 Downloads: 379 TO CITE АНОТАЦІЯFood security is one of the most fundamental challenges facing many countries, especially in the developing economies, which still has a vast section of its population still trapped in the socio-economic cocoon of poverty, unemployment, and inequality. This paper aims to investigate the institutional support in the facilitation of empowerment and development of youth Small, Medium, and Micro-Enterprises (SMMEs) to be active participants in the agribusiness economic mainstream. The paradigm shift from primary agriculture into urban farming business models in agri-business could accelerate the ascendancy of youth SMMEs in the competitiveness stakes. The theoretical analysis focused on the resource-based view model, institutional theory, and the role of the CSR impact as a conceptual framework for the study. The research design was predicated on the quantitative methodology, which enabled the researchers to statistically test the reliability and validity of the theory. The findings indicated that the CSR interventions had not yielded a fundamental impact on assisting youth SMMEs within the agribusiness sector. The results also identified a lack of tangible and result-driven institutional support from policy-makers and authorities. Overall targeted technological transfer as a strategic and critical resource to youth SMMEs is another constraining factor from empirical findings. The results also revealed the lack of monetary and non-monetary access by youth SMMEs as hampering their competitiveness and profits ability. The findings advocated that the policy-makers could synthesize the theories encapsulated in the study and the empirical evidence as the bedrock for bespoke, customized, and tailor-made youth SMMEs’ bespoke support, empowerment, and development of their entities.
