Abstract
Business sustainable competitiveness is a very complex concept. This complexity generates a variety of possibilities to define, to measure and to test it. The purpose of the paper is to develop the concept of businessness (for business sustainable competitiveness) by leveraging productivity, profitability, effectiveness and sustainability, at firm level. The interrelations between them, in terms of revenues per employee, return on assets, total assets turnover and Dow Jones Sustainability Index, were integrated into models/functions in order to develop, test and apply businessness. The article is about proposing functions (by using multiple discriminant analysis) in order to measure business sustainable competitiveness (businessness). The hypotheses and functions were tested using a sample of 500 companies (2000 observations) from Global Fortune 500. The results showed that there are direct and positive interrelations between the following items: number of employees, revenues, net income and total assets, but with different degree of correlations between groups. Therefore, it is very important to consider industry/group when conducting an analysis on business sustainable competitiveness.
